How to choose a fan in the bathroom and toilet?

The main distinguishing feature of the bathroom is its high humidity. As a rule, the bathrooms in modern apartments are not particularly spacious, so the room becomes damp for a short period of time. Water settles on the floor, ceiling and walls. For this reason, moisture resistant materials are purchased for finishing in order to minimize operational problems. An important requirement for this room is the intake of fresh air. The fan is designed to provide a solution to this problem. Let's talk about how to choose a fan in the bathroom and toilet, by what criteria to buy it.

If there is no fan?

This situation is terrible, not only and not so much damage to finishing materials, but also because the dampness negatively affects the well-being and health of people. The appearance of fungus and mold is especially dangerous for people prone to allergic reactions.

To avoid these problems, you need to install a fan, since natural air exchange systems, as practice shows, can not cope with this task. And in the summer, they do not work at all. Add to this also clogging over time.

Types of fans

Consider the main types of fan technology. All fans are usually divided into the following categories:

• Axial.
• Roof
• Channel.
• Radiator.

Axial

The main part of the axial structure is the wheel placed inside the cylindrical body on the axis of the electric motor. The wheel is equipped with special blades. The blades direct the flow of air. A collector installed at the inlet to the hood improves the aerodynamic performance of the structure.

Compared to other varieties:

• Axial models have the best features.
• Installation is extremely simple. The fan is installed directly into the ventilation shaft.

Ease of installation and use is one of the reasons that axial models are one of the most common.

Important! There is a significant drawback - not the best pressure qualities. In addition, the device is quite noisy in operation.

Radial

The fan is a wheel with blades mounted in a spiral casing. From the casing, air passes into a special discharge opening. The working cylinder is hollow inside, with special blades attached on the sides, equidistant from each other. This enables the device to work more efficiently.

Important! The advantages of the radial design are almost silent operation and economy (reduction of energy consumption, compared to the previous model, ranges from 20 to 30%). Good pressure characteristics and compact dimensions are also among the advantages of the radial model.

Centrifugal

These fans appeared on the market relatively recently. The centrifugal design is easy to install. In addition, it is easy to operate. These models have proven themselves in spacious bathrooms, the footage of which exceeds 15 squares. Typically, the centrifugal device is mounted under the ceiling and closed with plasterboard decor.

Important! The disadvantage of this device is the need to install an anemostat, which prevents the penetration of moisture into the fan.

Roof

These devices are mounted on the roofs of houses.In addition to the fan, the system includes: an electric motor, automatic regulation, as well as sound-absorbing gaskets. These devices use multi-blade axial or radial fans for single or double suction.

How to choose a hood?

First of all, when choosing, you need to pay attention to the technical characteristics of the device.

Performance

To correctly evaluate this indicator, you need to know 2 parameters:

• The volume of the bathroom.
• The number of indoor air changes per hour. This parameter is called the air ratio.

The performance of the ventilation device is obtained by multiplying these two numbers.

The multiplicity of air is a parameter that is regulated by building codes and depends on the type of room. For bathrooms, the multiplicity value is 6-8:

• For families of 1-3 people. the multiplicity is taken equal to 6.
• If the family has more than 3 people, it is better to take 8.
• The variability of the frequency of air for the toilet room is 6-10.

Important! Using real source data, you can choose a hood in the bathroom, which will better cope with the tasks. Typically, the performance of fans purchased in the bathroom ranges from 95 to 100 cubic meters per hour.

Noise at work

In the process of engine operation, noise occurs, or rather, its 2 types - mechanical and aerodynamic:

• Mechanical noise is generated directly by the engine.
• Sources of aerodynamic noise are vibration of fan elements and ducts.

At a noise level of 35 dB, discomfort usually occurs. Therefore, the maximum noise level that can be tolerated when purchasing a ventilation device is 30 dB. If you plan to operate the fan at night, then the value of the indicator decreases to 25 dB. All these data can be found in the technical data sheet.

Important! The noise level can be reduced by lining the inner surface of the duct with a material with a sound-absorbing effect.

Security

An important point is the moisture-proof performance of the device. The bathroom is always humid, and the fan is powered by electricity. Therefore, the issue of moisture protection is one of the important. Choosing built-in fans in the bath, you need to look for models with the appropriate markings. For safety, the bathroom is equipped with devices designed for only 24 V. Even with a short circuit, the device is completely safe.

Functionality

Distinguish between standard and automatic fans:

• In a standard system, the hood starts working with the light on. This is convenient, but practicality is rather dubious, especially with strong humidity. Excess moist air simply does not have time to move out of the room.
• The cost of automatic systems is higher, but they are more practical and functional. Devices are equipped with special timers. After you leave the bathroom, the system runs for about 25 minutes and then shuts down. When the air humidity increases above a predetermined limit value, the fan unit turns on automatically.

Important! If the ventilation systems of the bathroom and kitchen are a single whole, then devices with a non-return valve will become a real find. The latter does not allow air removed from the bathroom to enter the kitchen.

The combination of quality and value

It is advisable to choose a fan in the bathroom and toilet from well-known companies. Do not be too lazy to look for reviews on the forums. The likelihood that you can purchase good equipment will increase.

Bathroom Fans Rating

The rating list includes the best bathroom fans of 2017. Buyers, choosing a hood, are guided by the following parameters:

• Security.
• Power.
• Noisiness at work.
• Convenience of management and operation.
• Reliability, quality factor.
• Additional functions.

Now consider the best models.
