Fans for the bathroom: what are and how to choose?

High-quality fans for the bathroom today are in well-deserved demand. This is due to the fact that we are talking about the wettest room in any apartment or house. In such cases, you should know what the exhaust devices are and how to choose the most suitable model in each specific situation.

It is worth noting that in apartment buildings there are ventilation system channels, including in the bathroom. Based on this, some homeowners do not consider it necessary to install an exhaust fan in the bathroom. The mentioned channels for natural extraction extend from the first floor and exit onto the roof of the house. However most often the effectiveness of such structures is not enough to create a comfortable microclimate, especially in conditions of high humidity.

Those who are considering the possibility and expediency of equipping the bathroom with an exhaust device should consider the following important points:

• humidity indicators in the region;
• tightness of windows and doors, which is able to prevent the penetration of fresh air into the room for natural ventilation;
• the correct design and operability of ventilation ducts necessary for the circulation of air masses;
• the location of the house (special attention should be paid to buildings located near water bodies or in areas with an elevated level of underground water);
• in regions characterized by a hot climate and lack of winds, natural ventilation systems of rooms, as a rule, are not effective.

It is necessary to focus on the key advantages of installing a hood with a fan. The list of such includes the following factors.

1. The ceiling and walls of the bathroom will almost immediately cease to become damp. Therefore, mold and mildew will not appear, and condensation will not form.
2. The main advantages of modern devices include the maximum ease of installation and operation. In most cases, you can install the fan yourself, having basic skills and a minimal set of tools.
3. This equipment for drawing does not require complicated maintenance.
4. Most models are compact, so even the smallest rooms can be equipped with them.
5. More than a rich assortment of models allows you to choose the best option, taking into account different criteria, including the features of the interior of the bathroom or toilet.

In this case, you should pay attention to the following points:

• the devices in question are electric, and their operation is associated with certain (insignificant) costs;
• in some situations, the fan may make noise during operation, creating discomfort;
• To extend the life of the device, it is necessary to periodically clean and lubricate it.

In fairness, it should be noted that all of the listed minuses are fully leveled by the indisputable advantages of exhaust fans. This is most relevant for modern models with check valves, timers and electronic humidity sensors.

As already noted, the need to install equipment is determined in each case individually. In this case, the key point will be fan model selection. In such a situation, it is worth considering the varieties of exhaust devices available on the modern market.

Analyzing the varieties of proposed exhaust devices, It is worth focusing on the introduction of advanced technologies. And in this case we are talking about centrifugal installations for forced ventilation. The designs of these powerful low-noise devices include:

• wheel with blades;
• channels having a round or rectangular cross section;
• mechanisms for the injection of air and its absorption.

These installations are hidden and ceiling. Air masses are sucked in by centrifugal force and then pushed out by the next stream. The main advantages of such systems include:

• duct reliability;
• installation of a fan in front of the air intake or in the communications center;
• the possibility of operation in rooms with severe pollution;
• resistance to frequent and significant temperature changes.

Speaking about the disadvantages of centrifugal devices, it should be highlighted:

• low energy efficiency;
• susceptibility to voltage drops;
• the need to install an anemostat.

Recently growing in popularity roof structures. In addition to the fan itself, they include vibration isolation pads, adjusting devices operating in automatic mode.

Devices in this category represent a wheel located in a cylindrical body. On its surface there are cantilever blades. The whole structure is fixed on an axial electric motor, and the principle of its operation is based on the capture of air and its movement by the blades during the rotation of the wheel. To accommodate axial fans, holes are made in the ventilation ducts. The main advantages of such equipment include:

• high efficiency;
• ease of installation;
• lack of air ducts;
• resistance to load fluctuations;
• possibility of use at low pressure;
• compactness.

The list of significant disadvantages includes low air pressure and a fairly high noise level (up to 50 dB). To increase aerodynamic performance, it is recommended to install a collector at the beginning of the exhaust structure.

Considering the mounting features, exhaust fans can be divided into overhead fans (installed at the inlet of the ventilation shafts) and duct, which are located inside the ducts. By the way, in residential premises the first type of devices is most often used. DFor buildings (including residential buildings) with extensive ventilation system The second category will be relevant.

Now in the corresponding segment of the market a rather wide range of practically silent channel fans is presented. They are also divided into several subspecies.. At the same time, the microclimate created in the bathroom directly depends on the technical characteristics of the devices. One of the key points is the minimum noise level during operation.

An equally important characteristic of ventilation equipment is its performance. In this case, it is necessary to take into account the dimensions and design features of the room, as well as the system itself. Today, manufacturers offer potential buyers devices related to:

• axial, also called axial (most common);
• radial
• centrifugal models.

It is worth noting that the described fans can be installed practically anywhere in the duct.

All of today's forced draft devices are standardized.. At the same time, several basic fan sizes are provided. It is important to remember that when choosing a specific model the dimensions of the ventilation duct and the holes in it should be taken into account. Naturally, in some situations, the latter can be increased in diameter. However, such manipulations involve a certain amount of time and require corresponding efforts.

There is a whole list of design features of the various categories of equipment described.. Speaking about the diameter of the duct, it is necessary to clarify that there are standard sizes, namely: 100, 120 and 150 mm. Naturally, models with other parameters are also presented on the market.

As mentioned above, manufacturing companies provide their customers with more than a wide selection of components for ventilation systems. However, with such diversity, it is sometimes quite difficult to choose the best options. Actual and objective ratings of the most popular models can come to the rescue in such situations. For those who put the financial side of the issue at the forefront, the budget segment will be the best solution.

A model of an exhaust fan equipped with a check valve, which costs an average of 2 thousand rubles. Speaking about the main characteristics of the fan, it should be noted that its power is 7.5 kW, and its performance and noise level are 97 m3 / h and 25 dB, respectively.

As noted above, the modern market is able to satisfy almost any needs of a potential consumer due to more than a wide range of products presented on it. Choosing the best option, you should consider a number of important points and certain recommendations.

First of all, experts advise Pay attention to performance. This indicator is a multiple of air exchange. An important point in this case will be the number of residents. So, if the bathroom will be used by no more than 3 people, then the installation should be a multiple of 6, and if more than three - 8. By the way, the following performance indicators (m3 / h) are established by relevant sanitary standards:

• the minimum is 25;
• for combined bathrooms - 50;
• for wall mounting hoods - up to 100.

No less important selection criteria will be safety and noise level. It is worth noting that in the context of current standards, the latter indicator varies in the range of 25-30 dB. If the interior walls in the house or apartment are thin, it is recommended to arrange sound insulation of the ventilation duct. They deserve special attention dust and moisture protection. It is on these characteristics that the degree of risk of a short circuit and failure of the wiring depends.

In addition to all of the above, when choosing a model of an exhaust fan, you must consider nozzle diameter, and installation features of the device. Most often on the market you can find devices whose nozzle diameter is 100, 120 and 150 mm. Equipment can be installed both outside the ventilation system and inside it (overhead and duct models). In the first case, the fan is mounted on the wall or ceiling of the bathroom.

So, the fan housing is cast from ABS or plastic, the main characteristic of which is maximum resistance to mechanical stress.

Do not forget and about how to connect ventilation devices. In most cases, fans are activated when the light is turned on in the room. For many potential buyers, one of the key factors will be a list of additional options. In particular, fans can be equipped with:

• timers that are adjustable and unregulated;
• motion sensor;
• Remote control;
• own switch;
• air aromatization system;
• automatic blinds;
• the system responsible for protecting the device from moisture;
• integrated radios.

When choosing a fan for a bathroom or a bathroom, the following important points should be considered:

• on the case there should be no damage and seams;
• increased power will cause a corresponding consumption of electricity;
• radial models are characterized by minimal noise;
• the best choice for frequent use are overhead fans;
• constructions that belong to the category of ducts are suitable for houses with a branched ventilation system.

In addition, please note that The maximum efficiency differs devices equipped with a system that controls the humidity in the room.

Many popular models of exhaust devices can be installed independently. In this case, the entire installation process will be as simple as possible. To perform all the necessary work will require minimal skills. The algorithm includes the following steps.

1. Remove the front panel of the device.
2. Connect the electrical wiring through the terminal block. It is important to remember that the blue wire corresponds to zero, and the phase is red, white or black.
3. Place the fan in the vent hole.
4. Fix the device case using the dowels and screws included in the delivery.
5. Replace the cover and mosquito net, if any.

When installing the described elements of the ventilation system, it is necessary to take into account several of the most important points.

1. The ventilation shaft must be operational. Otherwise, the entire exhaust system will be ineffective.
2. The moist air drawn from the bathroom must be replaced with fresh air. To do this, take care of the presence of small gaps under the front door that provide circulation.
3. The ventilation efficiency directly depends on the correct selection of the model of the exhaust fan, taking into account all of the above factors.

It should be noted that such openings are available in almost all apartments and are an integral part of natural ventilation systems. It is important to consider that the standard channel, provided it is in good condition, is able to provide unhindered discharge of the air blown by the fan. At the same time, performance indicators can reach 100 "cubes" per hour.

When buying a fan, mistakes are often made with the choice of the diameter of its branch pipe. If there is no way to exchange the device, then here you can find a way out of the situation. The narrow outlet of the ventilation duct is expanded with a perforator. In situations where the device’s nozzle is less than necessary, you can use inserts from plastic pipes, and fill the voids with mounting foam.

In addition, when installing hood equipment attention should be paid to the wiring diagram for the power source. At the same time, it is best to lay the wiring in advance, during the repair and finishing works. An alternative could be use of practical cable channels.
