An air duct for hoods in the kitchen: types of products in shape and size, installation features, installation tips

Paying attention to the little things can go a long way toward keeping our homes comfortable and effective. The ventilation system is one element that is frequently disregarded, especially in the kitchen where cooking can produce a lot of heat, steam, and smells. The hood air duct is a crucial part of this system because it helps to purge the air of cooking fumes, grease, and smoke. This post will discuss the various kinds of air ducts that are available, their sizes and shapes, as well as important installation features and advice.

Let’s start by discussing the different kinds of air ducts that are frequently found in kitchen hoods. To accommodate varied kitchen layouts and hood designs, these ducts are available in a variety of sizes and shapes. There are various options to suit varying needs, ranging from small to large and rectangular to round in shape. The size of the kitchen, the kind of hood being installed, and the design of the house all influence the shape and size of the duct that is chosen.

There are a few important things to think about when installing an air duct for your kitchen hood. Maintaining a healthy indoor environment and the effective functioning of the ventilation system depend on proper installation. The duct’s material is one crucial consideration. Numerous materials, such as flexible plastic, aluminum, and galvanized steel, can be used to make ducts. Regarding cost, ease of installation, and durability, each material has advantages and disadvantages.

Making sure the duct is appropriately sized and positioned to allow for optimal airflow is another crucial installation step. Reduced ventilation efficiency can be caused by ducts that are too short or too long, and cooking fumes and odors may not be adequately captured by ducts that are placed incorrectly. Additionally, it’s critical to make sure the duct is correctly sealed to avoid leaks, which could compromise the ventilation system’s efficiency and result in problems with indoor air quality.

Let’s talk about some useful advice for installing an air duct for your kitchen hood now. To guarantee that the duct is installed correctly and safely, it is crucial to pay close attention to the manufacturer’s installation instructions. If you’re unfamiliar with ductwork installation, you may need to speak with a qualified HVAC technician or contractor. In order to keep your ductwork in good shape and continue to function effectively over time, it’s also a good idea to regularly inspect and maintain it.

Types of Products	Shape and Size
Rectangular Ducts	Commonly used for range hood installations, available in various sizes to fit different kitchen configurations.
Round Ducts	Efficient for air ventilation, especially in tight spaces where rectangular ducts might not fit.
Flexible Ducts	Perfect for situations where space is limited or when a more flexible installation is required.
Installation Features
Proper Sizing	Ensure the duct size matches the hood"s exhaust capacity to maximize efficiency.
Route Planning	Plan the duct route carefully to avoid obstacles and maximize airflow.
Sealing	Properly seal all joints and connections to prevent air leaks, ensuring efficient ventilation.
Installation Tips
Professional Installation	Consider hiring a professional for complex installations to ensure safety and optimal performance.
Cleanliness	Regularly clean and maintain the duct system to prevent grease buildup and maintain airflow.
No Sharp Bends	Avoid sharp bends in the ductwork as they can restrict airflow and increase noise.

Noisiness

If the device produces little noise while in use, particularly if it is not operating at maximum speed, it won’t cause any discomfort. When operating at maximum power, the loudest models can produce sounds as high as 72 dB, which is obviously very loud and uncomfortable to listen to. In contrast, the sound of a sewing machine produces noise of 70 dB, a traditional vacuum cleaner produces noise of 72 dB, and a two-person conversation produces noise of 50 dB. Some businesses incorporate mufflers into their products, which greatly lowers operating noise.

What to look for when choosing

The hood’s primary function is to purify the air. You must accurately calculate power and performance in order to accomplish this. The room’s area and volume are its primary parameters. Power calculations will be aided by the table.

Materials

Enameled hood

During use, the hood’s construction material is also crucial. It’s not always convenient to take care of an attractively designed device. To get rid of fat droplets from the body, the hood needs to be cleaned two or three times a week.

• made of cheap heat -resistant plastic;
• enameled;
• Metal.

The option made of plastic is not the best. Abrasive chemical detergents rapidly remove paint. Surfaces with enamel are stronger. The most useful cases are made of metal.

A glass hood for the kitchen is a pricey but inconvenient fix. It gets scratched up over time, and the appearance gets worse. Glass needs to be cleaned every day to remove any stuck-on fat.

Form and size

The devices’ good size fit into the kitchen’s interior is what matters most. particularly if the hood is bought after the furniture is installed. The most crucial dimensions are both width and depth at the same time.

For angular models, it is imperative to ensure that the case does not obstruct the nearby cabinets’ doors from opening.

Installing a fireplace hood is possible if the vertical space permits. In terms of cost, style, and features, this is the greatest choice.

Technical specifications

When making a decision, you should take into account factors such as power and performance.

• noise level;
• control method;
• fan system;
• The presence of backlight.

Selecting electronics with noise levels under 40 dB is advised. Although the unit will cost more, productivity won’t be lost while it operates silently.

There are three possible control methods: mechanical, sensory, and liquid crystal display. The buttons on the device’s front panel can be costly for someone who dislikes new technologies. His work does not deteriorate as a result.

Single-axis motors with a single or double impeller and dioecious motors with two fans are also available. Manufacturers install two engines with dual impellers to increase absorption power. A single-moving engine with two fans is the ideal choice.

These days, all hood types have backlights installed. Halogen lamps are the most robust and provide a powerful stream of light. In the kitchen, they can function even with minimal lighting.

Filters

It is advised that you consider the kind of filter that the model you like has. Selecting a multi-stage air purification system is advised.

The fat filter can remove dirt and soot from the air while also removing small fat particles from the air. The gadget will last longer without needing repairs because none of this settles on the duct’s interior walls or the equipment’s specifics.

The most resilient fat holders are those composed of multiple layers of perforated aluminum. Every two weeks, they are cleaned in a degreasing solution. It is safe to use until the part’s color changes.

Coal filter delay is carried by smell. This is the primary feature of running and desirable in recirculation hoods.

You’ll need an extractor grate in the kitchen to go along with the device. This component is essential to the wall’s aesthetic appeal where the unit will be installed. It is chosen based on the color of the equipment, tiles, or whitewashing.

Aluminum

Although they are also available, aluminum ducts have a number of drawbacks.

The following characteristics of a material that is frequently used in the production of corrugated pipes for ducts:

• Low price.
• It has different sections per calculating various air exchange intensity.
• The presence of numerous folds contributes to the settlement in the walls of the corrugation of hard -to -tribute fat deposits.
• Installation ease: corrugation is stretched to the required length, easily cut with ordinary scissors, the output can be given any shape.
• Not afraid of high temperatures, but with increased humidity in the kitchen, condensate can accumulate.
• It has a non -aesthetic appearance, so corrugated aluminum ducts often have to be hidden in the box.
• Low strength, often break during installation and external mechanical effects during operation.

Gypsum card

Unattractive communications are usually concealed behind the exquisite kitchen set’s facades, under a coat of paint, or inside a decorative square box made of drywall, plywood, or lining. The latter requires some basic GKL handling knowledge to assemble. A decorative box for a domestic duct air duct can be gathered by anyone who knows how to hold the tool in their hands. It is preferable to complete this while also fixing the room and installing the duct.

Preparation

Gather the supplies and instruments needed to assemble the box:

• knife for drywall;
• construction pencil (or marker);
• mounting level;
• scissors for metal;
• yardstick;
• recitting thread;
• screwdriver;
• electric drill;
• milling cutter (in case of installation of spotlights in the box).

Any cutting tool up to the blade can be used to cut drywall sheets. Novice masters, however, ought not to dabble.

Apart from the ceiling drywall, the following materials are required:

• metal profile or wooden rails for the frame;
• self -tapping screws and suspensions;
• universal putty;
• Material for decorative decoration.

Installation

Select the location for the exhaust unit and plate installation before putting together a drywall box for extract. Usually, the box covering the duct is located next to the wall or ceiling. Seldom does it go on the ceiling alone (for island hoods). To install the frame, make sure you mark the wall.

1. We make a duct as it will run.
2. Marking for rails.
3. Remove the pipeline and fasten the guides according to the markings. The profile is attached to the wall using self-tapping screws, which are twisted with a step of 300-400 mm.
4. When the guides for the box are fixed, we proceed to the assembly of the frame. First, the crossbars connecting the guide profile with the suspended elements of the structure are attached. Step between transverse rails – from 300 to 500 mm.
5. Next, we fasten the longitudinal elements. If the box is planned in the corner, then the suspended bar will be only one.
6. When the frame is ready, install the duct, firmly fixing and sealing all the joints. If the box is with illumination, at this stage the table summarizes the necessary communications.
7. Cut fragments of drywall of the desired size and fasten the elements to the frame using self -tapping screws.

It will be necessary to cover the hood box with putty and apply a decorative finish once it is fully assembled. The box can be designed to blend in with the surrounding area or stand out as a distinct feature of the room.

Flexible and hard products

The ducts for kitchen hoods come in a wide variety of styles. All products, for instance, can be categorized based on the materials they are constructed of. This quality directly affects a product’s ultimate cost as well as its operational features. But there are many other factors that also contribute to the division of the air pipelines.

There are two categories into which all structure types fall:

1. Flexible – can be placed at different angles. If necessary, it is permissible to compress or stretch them (of course, within a reasonable one). However, it should be borne in mind that the weakly elongated duct is much better resisting air flows. This helps to reduce the efficiency of the ventilation system as a whole. Such designs are often made from aluminum. The main drawback is that experts do not advise making a corrugated rosor with a length of more than 3 m. This is due to the fact that each extra meter will reduce the performance of the system by 10%.
2. Strong constructions are characterized by simplicity of assembly. In addition, the inner surface of such products is smooth and even. The price of these models is much higher, but their positive properties justify the cost.

Types in form

Form is one way to categorize air ducts. There are various options for products available today:

1. Rounded – are less universal compared to square. They can be installed in rooms with high ceilings. This requirement is explained by large dimensions of structures. If the output is made in the form of a rectangle, the use of special adapters of the desired section will be required.
2. Square and rectangular ducts for hoods in the kitchen are most often used. Many owners prefer this form due to the fact that such designs can be placed directly behind the cabinets in the kitchen. Because of this properties, it is possible to lay the system from the ventilation shaft to the hood along any trajectory. Rectangular structures will perfectly fit into the room of any height. In addition, models are characterized by a presentable appearance. Such units often have less performance compared to other types.
3. Oval products are characterized by the advantages and disadvantages of rounded structures.
4. Flat air ducts are one of the types of rectangular products. In view of small sizes, they are almost invisible.

A different item should be used to distinguish rectangular structures. Manufacturers create these items in various sizes:

• 110×55 mm – used for exhaust systems with a capacity of not more than 300 m3/h;
• 120×60 mm – used for hoods with a capacity of up to 350 m3/h;
• 240×60 mm – the ideal option for working in combination with high -performance devices, withstand a power of not more than 1000 m3/h.

Installation

How to install a corrugation on an extract in the kitchen yourself and why? For the air to be updated regardless of whether the hood is turned on or not, it is worth attaching the corrugation through the grille to the ventilation hole. Because in the hole there is a compartment for the duct and for air removal. When installing, it is also necessary to take into account the technical characteristics – the size and length of the pipe, otherwise the whole work done will be inappropriate. Remember the quality and reliability of the material you have chosen. In addition, it is better when everything is done in the same style, under the interior. It should be understood that the cost does not guarantee the proper installation, so study the poll. It also says how to install a duct for hoods in the kitchen.

How to choose the size

A roulette must be used to measure the entire length. Additionally, consider the path that the duct will follow. It could travel through the cabinet, along the walls, or even on the ceiling. It should be added to the overall length by roughly 10 to 15 percent after computations. Prior to attaching the hood to the corrugation, this is a crucial point.

On the other hand, if there is insufficient material, you can use tape to secure the missing piece; however, this will narrow the air duct’s path. This should only be used in dire circumstances. The hood is capable of much more coordinated operation with the fewest angles possible, but with a greater degree.

How to fix the corrugation on the hood

To attach the corrugation to the hood in any way, you’ll need:

• corrugated tube
• Self -tapping screws
• Clamps for fixing the sleeve or soft wire
• grate for ventilation or adapter
• silicone sealant
• adapters, there was no corrugation corrugation

When all the tools are prepared, here’s how to attach the corrugation to the hood:

1. Before work, the ventilation in the apartment should be cleaned
2. First, stretch the corrugation along its length, check the constituent elements. Avoid bending, then air traction will remain good.
3. With the help of sealant, lubricate the neck of the hood
4. Put on the corrugation and fix it with a clamp, if it is not, then wrap it with wire.
5. It is necessary to lay this to the end of the ventilation hole
6. Fix the grate for ventilation with self -tapping screws
7. Then put on the corrugation with sealant
8. Fasten the work with a clamp
9. Check the exhaust system by connecting the hood to the network. This is done as follows: turn on the hood for maximum power, now take a sheet of paper and bring it from the bottom to the grate. A sign of proper mount is the retention of the leaf – it means that the air is absorbed. Everything, the problem of how to put a corrugation on the hood, solved.

MENTIONED Refrain from wiping the exterior; this will protect you from unpleasant odors.

You must be aware that the ventilation hole is required. The shaft cannot be fully closed.

If you do not want the corrugation to be on public review, that is, the opportunity to hide it. How to insert the corrugation into the hood inward so that it is imperceptible? This is easy to do with the doors of hinged cabinets, a decorative box or other elements. To mask it, you need to choose the color of the furniture. To give harmony, try to arrange everything based on the style of the kitchen. Another option is to establish a lining. It can be formed along the contour of the cabinet, thereby will ensure the secrecy of ventilation. It will not be difficult and lay inside the kitchen sets. However, this will be lost a lot of the necessary space, as well as the holes that need to be cut out.

You can just order a professional installation if you don’t want to know how the corrugation is fastened to the hood. particularly if the hood was ordered along with the kitchen. Then, the conventional plan may not be followed when installing corrugation for hoods.

Why is the installation of corrugation on the hood

Utilizing corrugated pipes is beneficial due to their numerous benefits. For instance, the majority can afford to have them installed, and it turns out that installation is not too difficult. They also come in a wide variety of shapes and sizes, and when compressed, they weigh little. able to withstand high temperatures without burning. The fact that it can be installed both indoors and outdoors speaks to its functionality. are employed in various system domains and positioned on various planes. When the room will always be fresh, it only makes sense to take care of it once.

The specifics of the arrangement of kitchen hoods

A kitchen hood installation will require additional materials in addition to the equipment itself, such as an air duct and fasteners to it, a box, and fasteners for its installation.

It is advisable to purchase the additional supplies required for connecting right away. It is more practical if every part belongs to a single trademark because color and size will match exactly.

Subtleties of choosing and installing air ducts

The following types of air ducts are available in construction supply stores:

• corrugated polymer;
• aluminum corrugation;
• corrugation made of stainless or galvanized steel;
• plastic round pipe;
• Plastic rectangular duct.

Plastic pipes with round and rectangular sections and aluminum corrugation are the most commonly used materials for home ventilation arrangements.

This is because the installation process is so easy that even a novice home master can handle it.

The least desirable option for a duct is a plastic corrugated pipe. Purchasing an aluminum analog is preferable.

Plastic corrugation is added to a few of the kit’s less expensive hood models. Whether or not to use it depends on the kind and dimensions of the plate that must hold the exhaust equipment.

In the event that a gas stove is present in the kitchen, the masters would rather purchase high-quality metal corrugation from a reputable supplier than the plastic kit.

You should select a high-quality product when setting up a home ventilation system. Ignoring treatment can lead to the burst of too-thin and fragile foil corrugation.

In certain interior designs, a metal corrugated pipe blends in harmoniously without requiring creative solutions for its masking. However, in order to maintain the harmony of the kitchen area, it must typically be hidden in every way.

When paired with a pricey natural wood kitchen set, aluminum corrugation appears at least absurd.

Installing the corrugation is easy: just attach one end to the hood’s pipe and place the other end into the ventilation shaft’s grate.

Sealant, clamps, and aluminum adhesive tape are used as fasteners.

With careful cutting with scissors, the corrugation can be easily stretched and bent in any direction. This enables you to create complex, lengthy channels without making abrupt turns.

Plastic pipes that are rounded or rectangular have a more attractive appearance. They don’t flex in various directions. Since every detail is connected to every other detail as a constructor, installing them won’t be too tough either.

They purchase specialized adapters in order to join. The fact that the turns are not as smooth as they would be in a corrugated pipe makes them uncomfortable.

The geometric clarity of the lines is without a doubt the benefit of such air ducts. This gives you the ability to look naturally among other kitchen furniture that has rigid geometry.

The option you choose for your kitchen should be the one that blends in with the interior design more naturally. If purchasing an air duct will only cost a very small sum of money, you can purchase cheap aluminum corrugation and cleverly conceal it.

It is important to note that a corrugated pipe’s desired meter is measured in a stretched form. Additionally, since the turns will be obvious, the length of the smooth plastic pipe that is needed should be precisely measured at home.

You must purchase all pipe adapters right away, ideally from the same manufacturer.

The thrust of the ventilation canal does not adequately represent the use of adapters from a round to a rectangular section and vice versa. It would be wise to reverse this choice if at all possible.

A crucial consideration when purchasing a ventilation canal is choosing the appropriate diameter as advised by the hood’s manufacturer. A smaller or larger pipe size will make the equipment operate less well. Buying all of a company’s fasteners is also the best option.

Equipment options for equipment

It just needs to be installed and connected to the ventilation system after the hood and all other parts are purchased.

There are two ways to go about doing this kind of work:

• with your own hands;
• the hands of a professional.

Every option has advantages and disadvantages of its own.

The order in which the hood’s flexible air duct construction is completed will show the following photos:

You will need to pay a reasonable fee for the services of the masters if you choose to trust them.

Furthermore, it is absurd to designate a cheap brigade because they may be "out of hand" by unscrupulous professionals who damage pricey equipment.

Adapters, clamps, fasteners, silicone sealants, and other consumables might be required for installation. They ought to be purchased with a box and duct after careful calculation.

If the home master has some prior construction or repair experience, the first option is more dependable. When an owner completes everything by hand, he is aware of what is delivered and where.

Furthermore, nobody will fool themselves; all tasks will be completed effectively. To keep the guarantee on the hood intact, all you have to do is carefully read the instructions.

When working independently, these are crucial:

• safety;
• correct connection;
• Great appearance.

It is vital to precisely adhere to the specifications of the manufacturer’s instructions and recommendations in order to guarantee the safety of the installed ventilation system element. After all, every hood model has unique features.

Stainless steel is more resistant to the effects of higher temperatures than plastic, so the materials used in manufacturing are also different.

You will need metal clamps, adapters, and a ventilation grille in order to work with stainless steel kitchen components.

You have to first attach the kitchen hood before you can connect it independently to ventilation. The operating manual’s manufacturer recommendations will be helpful in this regard.

Every kind of hood has specific installation requirements. For built-in models, for instance, the kitchen cabinet’s bottom will need to be drilled, and new fasteners will be needed to attach the domes to the wall.

After the hood is in place, you need to connect a duct, the other end of which is connected to the house’s ventilation shaft entrance. Installing the check valve right away won’t be unnecessary.

The type of duct that connects the kitchen hood to the ventilation system determines how long and how complicated the subsequent work will be.

Round-section, smooth plastic pipes in light colors blend in nicely with the kitchen’s decor.

It is necessary to conceal the chosen ventilation channel if it does not complement the overall stylistic composition. Particular boxes are used for these purposes.

These items have the dual purpose of decorating the kitchen and concealing the duct. However, the mastery of considerable forces and abilities may be necessary for their installation.

Types and nuances of the installation of ventilations

You can buy a specific box to conceal specific ventilation equipment components. The duct that is removed from the overall image must usually be hidden.

This is the part of kitchen ventilation for which you can construct a box by hand. Which choice is best for a given room will only satisfy its owner.

Even the most inventive room décor ideas can be destroyed by pipe meters that extend from the hood to the shaft. Selecting a masking option for an air duct is preferable.

The following options for the boxes are available for purchase, depending on the material of manufacture:

• plastic;
• aluminum;
• from stainless steel;
• Wooden.

Next, think about the attributes of every option that has been voiced.

Features of the use of plastic

Plastic duct pipes are commonly referred to as "boxes." They don’t need the use of any extra material for masking because of their distinct geometric form.

They can be painted with a heat- and moisture-resistant paint if the proper shade isn’t available. By doing this, the ventilation channel will be able to blend in.

Expitable

Metal filing cabinets are a pricey fix. Through adapters, they are connected as one plastic unit.

However, because of their heavier weight, they need to be fixed more firmly along the ventilation duct’s path.

There are various thicknesses of stainless steel that can be used to construct an exhaust box. This material blends in amazingly well with the high-tech kitchen design. You won’t even realize that there is aluminum corrugation inside.

Wooden structure of the box

The room has a unique atmosphere thanks to the exhausted wood box. These kinds of products belong in wooden houses with simple, eco-friendly furniture pieces.

For the apartment, the use of wooden boxes is also permissible, the main thing is that the stylistic of the design of the kitchen corresponds to.

The materials specified by the manufacturer should be used for installing wooden boxes. When purchasing a box, it is best to buy all fasteners and adapters at once.

Making a gypsum cardboard box

Drywall is another material that was used in the box’s construction. It is utilized by experts who would rather create a ventilation channel design by hand.

You can implement any design idea with an exhaust box that is independently constructed, as opposed to depending on the standard sizes of products that you purchase.

Typically, a box of this type is set aside, primed, and painted a fitting hue. It has the backlight built in right away, during the installation phase.

This diverts attention and, with its two-story ceiling and extra lighting, gives the space an unusual appearance.

It is hard to believe that all of this is done to conceal the duct when you look at the ceiling level. It is preferable to invite specialists for such work.

Why does the check valve sometimes not work and does not close

The check valve is installed on the tee on the kitchen side. When executed in a factory, it will take a while. It is preferable to shorten it in this instance so that the "gun" does not protrude too much outside.

The D-125mm standard duct segment is where the valve is placed, and it is dressed and marked on the tee.

You can modify it slightly if you felt that the entire design was too complicated and that a sticking pipe with a valve was not very attractive. Instead of using round pipes for the duct, use rectangular channels.

Cut the above check valve in a straight section at the same time, as close to the turn as you can.

You will need to collectively farm as this location does not achieve the factory connection. One is purchased, a rectangular tee with a round exit on one side. The check valve is glued into place after this circle is further cut off.

Strictly speaking, the valve is angled (2 degrees). If not, it will either open at your convenience or not at all.

This approach has proven to be an easy solution for many who have faced this issue.

Additionally installed with a vertical deviation is the damper itself. If one is using the hourly dial, the upper rotary point is at 13.00 (1 hour), and the lower rotary point is at 17.00 (5 hours). This is presuming a right-to-left flow direction.

If not, the circle is positioned between 11 and 7 hours.

One possible solution to improve the damper’s stability and dependability is to apply a small amount of weight (no more than 2 grams) to one of the sides. Place more glue near the edge.

Additionally, never discard a round pipe cut. It is fitted firmly onto the valve from above, and then a diffuser grate is mounted on it for aesthetic purposes.

What subtleties might this approach have? In the event that a hood is situated precisely above the ventilation shaft entrance and the channel pipe runs straight through the horizontal plane without any turns, the valve installed on that straight section will not function normally—at least not at first speed.

There’s simply nowhere to find more pressure to shut it. This "turn" is going to travel straight ahead. Make sure you require an angle.

Installing the tee so that the middle knee rests against the wall is an option if you don’t want to see the sticking "hollow" under the ceiling at all. If not, the valve would look to the side where it is located. In this instance, a decorative lid is also used to seal the hole.

Everything will appear much more beautiful. However, because of an extra turn, natural ventilation’s performance will marginally deteriorate. Another interest will be lowered by twenty thanks to the lattice.

Furthermore, you won’t be able to clean the channel with a vacuum or your hands. However, a lot of people do this on purpose and even conceal the entire structure inside a box made of wood or plastic.

As they say, victims are necessary for beauty.

We’ll go into the various duct types, their sizes, shapes, and proper installation techniques in our article on kitchen hood air ducts. Kitchen hoods are crucial for eliminating smoke and cooking smells from our homes, but their effectiveness depends on the quality of the ducts that exhaust the air. We’ll talk about the different duct options—from flexible to rigid—and how well they work with the various kitchen layouts. Installation advice will address everything from determining your duct’s optimal path to making sure it is properly sealed for efficiency. Maintaining a well-ventilated and comfortable home requires knowledge of air duct options and installation techniques, whether you’re remodeling your kitchen or installing a new hood.

Extract for a kitchen with an air duct: installation of an air duct

If all the sizes are chosen correctly, installation of the kitchen hood duct starts with the building of the structure. Here are some crucial guidelines. The primary component of the channel is the material used to make it.

1. Plastic solutions. For these structures, the installation process is extremely simple. The duct is easy to fit in size, sawing it with a hacksaw, and then collect it very quickly. To increase the insulation of the structure, use a special sealant. To connect a rectangular pipe to a round hole of the ventilation duct, use special couplings and adapters.

1. Corporal channels. It is easiest to connect a corrugated pipe with a ventilation canal, since aluminum is stretched, which provides flexibility to the product. The corrugation has special fixing clamps in each side, which is several times simplifying the installation. Fastening is easy to perform a home tool.
2. Hardware. Installation of the duct for hoods is often more complicated than plastic solutions. The design is assembled according to the technology overlap. To ensure the design of optimal tightness, use special adhesive compounds. Fasteners are inserted into the holes made in the wall. For low strength, the structure is sealed with sealant.

When installing a kitchen hood by hand, it’s crucial to pay attention to how the metal structures and connecting parts blend in. Special decorative elements or furniture are used for this purpose.

Classification by materials

Air pipelines for equipment of the exhaust system are made from various materials. To determine which one is better to choose for a particular case, you need to study the characteristics of all units presented on the market.

Plastic structures

As of right now, kitchen hood plastic ducts are thought to be the most common. They have two shapes: round and rectangular. The latter appear more realistic and artistically pleasing. As a result, installing round products is quicker and simpler (adapters are not needed in these cases to join the duct and the hood). The primary benefits of plastic products are:

• rust resistance;
• Simplicity of assembly;
• low cost;
• Smooth inner surface minimizes the risk of accumulation of fat and other contaminants;
• small weight, thanks to which it is much easier to carry out installation;
• Lack of noise during the operation of the hood.

One drawback of plastic air ducts for kitchen hoods is that they frequently need adapters and other components for switching during installation. Furthermore, it is not advised to expose products to extremely high temperatures as this will cause dangerous substances to separate from plastic.

Steel and aluminum units

Products made of aluminum rank second in terms of popularity. Additionally, structures for the ventilation system’s equipment are made of this material. Principal benefits:

• Aluminum is a simple and universal material;
• Products are cheap;
• fast and simple installation;
• structures are resistant to high temperatures.

Like any other product, aluminum air pipelines have a number of drawbacks. Several of them:

• The material has high thermal conductivity. In the room where the duct of aluminum is installed, condensate accumulation is often observed.
• An unpresentable appearance. Often such units are hidden in kitchen cabinets or masked using special boxes.
• Aluminum does not differ in high strength, due to mechanical exposure can be subjected to deformations.

Air pipelines made of steel are commonly found. Stainless steel or galvanized steel are typically utilized in the construction of these kinds of structures. Galvanized products performed admirably when it came to use at home. It’s crucial to remember that these units are no longer as common as they once were. Steel ducts are less and less in demand each year. The primary benefits of these models are:

• Relative cheapness.
• A flat base that does not prevent the passage of air flows. In addition, dust deposits and soot do not accumulate in smooth products.
• Steel products are not subjected to deformations under high -temperature exposure. In addition, harmful substances are not released into the environment.

Steel units have certain drawbacks despite their many clear benefits. The latter are the cause of the decline in product demand.

• For fastening on the walls, the most stable and reliable fixation elements are required;
• To assemble a non -standard duct, you need to additionally cut metal pipes;
• large weight (especially compared to plastic structures), so it will not work to do it independently;
• To seal the channels, the use of special tools will be required;
• In the process of operation, a loud noise is felt.

Which duct is suitable for a built -in hood?

The built-in equipment is typically installed to save space; the range of built-in systems is 45 to 90 cm, so you can select an extract for any kitchen’s specifications.

The hood’s width should equal or exceed the width of the plate or hob in order to determine the hood’s size. These days, horizontal systems are the most prevalent.

Regarding vertical systems, their installation entails significant expenses and they are less prevalent. A plastic duct that is rectangular or corrugated is the best choice for installation.

A clean and healthy indoor environment depends on selecting the appropriate air duct for your kitchen hood. Since different kinds come in a variety of sizes and shapes, it’s important to take your kitchen’s layout, ventilation requirements, and installation requirements into account.

There are various options available to you when choosing an air duct, including round, rectangular, and flexible ducts. There are benefits and installation considerations for each type. Round ducts provide smooth airflow and are simpler to install in confined spaces, but rectangular ducts are frequently chosen for their efficiency in moving air. Although flexible ducts offer routing flexibility, they may need extra support to avoid kinking and airflow obstructions.

Careful attention to detail should be used when installing the air duct. To guarantee the best possible airflow and ventilation efficiency, proper sizing and routing are crucial. It’s critical to abide by local building codes and manufacturer instructions to prevent problems like air leaks, insufficient ventilation, and fire hazards.

The distance between the kitchen hood and the outside vent, any obstacles in the path, and the duct’s material should all be taken into account before installing the air duct. In addition to preventing condensation buildup and lowering heat loss, proper duct insulation can increase energy efficiency.

To guarantee the air duct system’s longevity and continuous performance, regular maintenance is required. Cleaning the ducts on a regular basis keeps airflow and prevents clogs by clearing out accumulated dust, grease, and debris. Furthermore, keeping an eye out for any indications of deterioration or damage to the ducts enables prompt repairs and guarantees continuous ventilation.

To sum up, maintaining a comfortable and healthy indoor environment depends on choosing and installing the proper air duct for your kitchen hood. To guarantee optimal performance and longevity of your ventilation system, take into consideration the different types available, adhere to proper installation guidelines, and prioritize routine maintenance.
