Installation of a fan for the hood in the bathroom with your own hands

Your bathroom hood’s fan must be operating correctly in order to maintain good air quality and avoid problems like mold and mildew. Although it can be expensive to hire a professional to install a fan, you can do it yourself if you have the necessary tools and know-how. With the help of this guide, you will be able to install a fan for your bathroom hood and enhance indoor ventilation, leading to a healthier living space.

It’s important to comprehend the importance of having a fan in your bathroom before beginning the installation process. Steam and moisture build up in the air after bathing or showering, which is ideal for the growth of mold and mildew. These can cause expensive damage to your home as well as health problems if there is insufficient ventilation. An appropriately installed fan contributes to improved indoor air quality and the avoidance of future issues by eliminating excess moisture, smells, and pollutants.

There are several things to take into account when selecting a fan for your bathroom hood. The most important thing to consider when choosing a fan for your bathroom is its size. This guarantees effective ventilation without putting the system under or overpowered. Furthermore, search for a fan that can efficiently remove moisture and odors from the area with an airflow rate high enough, expressed in cubic feet per minute (CFM). Finally, to locate a fan that suits your requirements and tastes, take into account features like noise level and energy efficiency.

It’s time to start the installation procedure now that you are aware of how important bathroom ventilation is and have selected the ideal fan for your requirements. Installing a fan for your bathroom hood is a doable do-it-yourself project with the correct advice, even though it might seem difficult at first. You can take pleasure in better air quality and peace of mind knowing that your home is better protected against moisture-related issues by following the steps outlined in this guide and taking your time to ensure everything is done correctly.

What is the ventilation system in the bathroom

More than other spaces, bathrooms almost always have high levels of humidity and are vulnerable to natural condensation when a regular ventilation system isn’t present. Consequently, this room starts to smell musty and gets wet from condensation on the walls, which helps mold and fungus grow quickly.

The best possible conditions for people to stay in their bathrooms will be created by an appropriate ventilation system, which will also aid in maintaining wooden furniture, electrical appliances, tiles, and other facing materials.

Nowadays, ventilation comes in two flavors: forced (artificial) and natural (natural). When windows are closed or do not open, making it impossible to create natural ventilation, a forced ventilation system is installed. This system calls for the installation of specific fans designed for these kinds of residential spaces.

In the restroom, an electric fan

Its design allows for ventilation to occur:

• Burnal. In this case, ventilation is produced in the bathroom through the holes in the wall of the common ventilations of multi -storey buildings.
• Channel. It is used to supply ventilation system to places that require the most intense and frequent air purification.

Also, even when the bathroom has natural ventilation, some owners of private homes and apartments would rather install a disconnecting forced system. As a result, you can guarantee that this room will always have a typical microclimate.

This is because many older homes that were constructed more than 20 years ago have general ventilation systems that are unable to handle continuously increasing loads. As a result, you must use more contemporary techniques to deal with excessive humidity.

Criterias of choice

Installing a forced-type electric fan is the most efficient way to create the proper ventilation. Usually, wall axial fans with different capacities are purchased for these uses.

Axial wall fan for forced air circulation

When selecting one of these devices, you should consider:

• Security system. The fan is a household electrical appliance, and the bathroom is a closed room with a high degree of humidity, so the device should have a maximum degree of protection of the body from water and steam entering.
• Noise insulation. The noise level of the device should be minimal so as not to annoy the people living in the apartment. If necessary, you can install a special noise and supplement it with soundproofing materials that are laid inside the fan.
• The power of the ventilation device must correspond to the dimensions of the bathroom and the number of residents. With insufficient power, the meaning of this system will simply be lost, since it cannot fully fulfill its functions.

Requirements for forced fans

• The noise level in a small room should be no more than 35 – 40 dB.
• The ventilation system should create a regular air change of at least 5-8 times in one hour and comply with SNiP standards.
• The hood device should have a check valve if the air output is made only through one branch.
• The case should be a moisture -proof class at least IP34.
• A 36 V engine will allow the device to work quite silently.

In the article about installing a bathroom fan yourself, the main idea is to guide readers through the process step by step, making it easy and approachable. It should cover the importance of proper ventilation in bathrooms to prevent mold and moisture buildup, which can lead to health issues and structural damage. The article should explain the benefits of installing a fan, such as improved air quality and reduced humidity. It should provide clear instructions on choosing the right fan size and type for the bathroom, locating the optimal installation spot, and wiring the fan correctly. Additionally, it should emphasize safety measures and common pitfalls to avoid during the installation process. Overall, the article aims to empower readers to tackle this home improvement project confidently and effectively.

Classification of exhaust systems

In terms of their positive attributes, fans can be:

Axial. The air flow is pumped up with fan blades. The pressure that he creates no more than 50 PA. Usually mounted in a non -channel ventilation system.

Many modern fans are equipped with additional functions

• Electric fans with a built -in motion sensor can recognize the human body in a radius of their “visibility” and turn on the engine. Such a system allows you to significantly save electricity.
• A fan with a timer is able to recognize a moving person and turn on the motor to start work. If the movement stops within its radius of its action, the device is disconnected.
• The fan with a temperature controller (humidity) depending on its design features removes hot air from the bathroom or vice versa, heats it. For the installation of such a device, a special scheme is provided that allows you to configure the optimum air temperature in the room. If the established norm is exceeded, the device engine begins to work, creating the necessary air exchange in the bathroom and preventing people.
• A check valve device is necessary to prevent the reverse air flow, as well as extraneous smells from the outside, when it does not work.
• The fan with the blinds is also designed to prevent air flow from the street during the shutdown of the device. Only in this case the blinds open and closed manually.

How to correctly calculate the power of the hood for the bathroom

It is advisable to determine the ideal level of system power before making a fan purchase.

The 6V or 8V formula, where V is the room’s volume and the numbers are the coefficients that indicate how many people are using the restroom, is used to accomplish this. We require a coefficient of eight if more than three people use it frequently.

Should the fan be linked to the light switch, it will only activate upon an individual’s entry into the restroom. As a result, less electricity will be used, allowing the system to operate only when absolutely required. However, not everyone wants to shower or use the restroom while a fan engine is buzzing. In this scenario, you could build him an independent switch that activates on its own when the room is unoccupied.

Another formula that can be used to determine fan performance (power) is:

• Determine the area of the bathroom.
• Multiply this figure by 5.
• We add another 20% to the result.
• It turns out the recommended fan power.

Installation of a forced ventilation system

Take a look at some fan installation guidelines first.

• The fan is mounted as close to the ceiling as possible and as far as possible from the opening window or door, otherwise only partial ventilation will be carried out, which is not able to affect other places of the bathroom.
• Should be as far as possible from any water sources in order to avoid a short circuit.
• The wires that go to the fan must be drowned in strobes or hidden under the ceiling (stretch or hinged).
• If there is no ventilation pipe in the bathroom, then you can install the PVC pipe for a sewage with a diameter of 10 cm.

Phased installation

1. We will consider how the fan is connected and mounted properly using the ERA 4S et example, which is equipped with a protective net from insects and an electronic timer. This model has a ball -bearing engine with maximum overheating protection.

How to connect a regular fan with a lace

The fan and lace connection is much simpler because no specialized knowledge of electrical circuits is required.

1. We install the fan in the outlet under the ceiling, as in the first case, but just do not bring any wires to it, since it will work from the power grid in 220 in a conventional wire with a plug.
2. "Power" a sealant fan so that it is tightly fixed. We turn on the wire in the outlet, and all. Now that we need to turn on the fan, we just pull the lace and the engine will start. After the room is completely ventilated, we will also need to pull the lace and turn off the fan.

Not only does this system require you to manually turn on the device, but it also requires an electric outlet to be nearby. If this isn’t the case, you’ll need to use an extension cord to connect a fan that’s mounted on the wall across from the outlet.

Checking the work

We can perform a quick test to verify that the ventilation system was chosen and connected correctly by taking a piece of paper and applying it to the exhaust system’s bars. The sheet will firmly "stick" to the grille if the room has good air circulation and specific ventilation is used to expel the air.

The fan needs to be made larger. The design would then seem more aesthetically pleasing if the channel cable zigzags were absent. I watch the training video. 🙂 Visit https://www.Asutpp.ru/elektrika-v-kvartire/ to access Michael Ventilyator-dlya-vannoj.HTML.

Kantovius: And the problem of mold is unlikely to solve the fan.Just the same, the fan solves this problem with 100% probability. Of course, if you have a mold, you put a fan and do nothing else, then the mold will remain in its place. First, mold should be removed and processed this place. And you won"t have it anymore. Kantovius: A cheap model will work out its own several years and put a new one.There is one good saying. We are not so rich to buy cheap. Why buy a new one when you can pay twice as much and use 10-15 years without problems. Moreover, I would very much advise paying attention to the level of fan noise. Think for yourself.
