Silent fans for exhaust in the bathroom: features of choice

The ventilation system has a special place in the improvement of the dwelling. Hood in the bathroom or bathroom with built-in silent fan is a compact, multifunctional and energy-intensive device. But because of the wide range of consumers often face the difficulties of choosing the right one. Consider the features of silent fans that will help you make the right decision when buying.

Each bathroom has a ventilation system. However, many, especially in the repair process, prefer to close it at the stage of finishing works. To do this in any case is not recommended.Provided that your toilet ventilation system operates on natural airflows, after a rather short period of time you will encounter the fact that the air duct will simply become clogged and will cease to fulfill its intended purpose. To avoid such difficulties, it is recommended to install forced ventilation, the equipment of which consists of a silent fan.

After installing the fan you will gain a lot of advantages. For example, get rid of the problem with the occurrence of mold and mildew associated with high humidity in the room. There is no need to deal with unpleasant odors, as there is a constant replacement of air. Indoors there will not be sharp temperature jumps if there is a home exhaust.

Today, there are several main types of silent fan, designed for exhaust design in the bathroom. All models differ from each other in properties and appearance.

Given the shape, silent fans can be divided into:

• round - designed for installation work in the channel of the same shape;
• rectangular - used very rarely, mainly in industrial premises;
• square - most often it can be seen in the mine, which has a square shape, has high rates of performance, in residential areas is not used at all.

If we talk about the fundamental characteristics of a silent fan, there are three models: channel, axial and radial. The channel model is intended for installation work in air ducts.

He has a list of positives on the background of other models:

• easy and simple installation - installation in the air duct does not take much time and effort, does not require special skills and knowledge;
• the channel model has multi-layer walls, which allows the fan to work at full power without creating annoying noise;
• the small size of the duct fan does not require a large space for installation; it will fit perfectly even into the smallest bathroom;
• enables the maintenance of ideal humidity indicators in the living space;
• comfort in exploitation.

The axial model of the fan has a cylindrical shape. Its package includes an engine, the blades of which are located along its axis. And additionally install the collector. With it, increase the aerodynamic properties and suppress noise emanating from the passing air flow. This model is a high-performance device and for an hour can afford to move up to one hundred cubic meters of air flow. As in the first model, the axial fan does not require special installation - it is necessary to attach it to the ventilation hole and fix it.

A wind radial model involves moving air currents.which coincide with the direction of the radius. In other words, the fan blades are located in both directions. But when the blades are positioned back, the emitted noise is significantly reduced, which allows increasing the productivity of its work. If the blades are located forward, respectively, an increase in productivity occurs, but the resulting noise will be several times louder. This type of fan has a small size, suitable for installation in the duct of any shape.

Electrovyazvyazhka must have a timer off and off.Delayed inclusion can come in handy in many cases.

The design can be connected to a light bulb, to a light switch, or to operate on batteries. Wireless automation is considered more convenient.

For the correct installation of the roof and axial fan manufacturers produce specialized designs, called mounting glasses. Its design includes a robust frame that includes a ventilation system with square valve sections.

For safe operation, as well as the collection and further removal of condensate, many manufacturers add a special tray to the fan kit. It is necessary to eliminate condensation residues. Their formation occurs in the field of glass and cooling elements in the ventilation system. Fastening is carried out in the lower part of the glass with the help of screws.

Among other things, you may encounter such a component as a vibration absorber. It is used to reduce the dynamic oscillations that are transmitted from models of radial fans.

Before purchasing the model you need, measure the ventilation system, namely its diameter.When choosing the size of the fan, regardless of the model, the main requirement is that the fan should be suitable in size to the ventilation system. In other words - the diameter of the silent fan must strictly coincide with the diameter of the duct. All manufacturers produce one version of the model with different diameters.

Most silent fans have standard sizes of ten, fifteen, twenty-five, and thirty centimeters. Their diameter is mainly 80, 100, 150 mm. This applies to all models: circular duct, radial and rectangular. In urban apartments for the bathroom characteristic duct ventilation systems are not more than fifteen centimeters. A fan with a diameter of more than sixteen centimeters is typical for large ventilation systems.

The productivity of the fans is one of the main properties that you should pay attention to when buying and further installing.

Productivity (or power) can be calculated by a specially created formula, which takes into account the entire area of ​​the room and the quantitative indicator of the air flow passing for sixty minutes.To obtain a specific value of the productivity of the selected device, it is necessary to multiply the area of ​​the room by the quantitative indicator of air exchange.

For bathrooms, there is a normalized indicator for determining duct exchange, taking into account how many people live (from six to ten), the average value is taken. When a fan is purchased, the power is selected on the basis of the resulting figure, to which an additional fifteen to twenty percent is added for the reserve. And only after all the calculations acquire the appropriate device.

For urban bathrooms and sanitary facilities with standard room parameters, the most demanded model is an exhaust fan with a capacity of up to one hundred cubic meters per hour. Based on this indicator, you can make a rating of brands of manufacturers.

If you wish to purchase an invoice axial fan, look at the brand Soler & Palau and Blauberg. In the first case, the fan capacity is from sixty-five to ninety-five cubic meters (depending on the model chosen). The noise level on all models does not exceed thirty decibels.

Basic model Silent equipped with non-return valve and bearings with a quiet course. The remaining models include the addition of a timer option, a room relative humidity sensor, and a wired switch.

Mark Blauberg offers you models of fans with a capacity of up to ninety seven cubic meters, with a noise level not exceeding twenty-five decibels. An option may be added in the form of a laced switch and timer.

For the manufacture of a channel axial fan championship belongs to the Bulgarian brand MMotors JSC. This brand offers standard models with a power of fifty cubic meters, with a noise level of up to thirty decibels at an operating temperature of 100-150 degrees Celsius. The design basically has only positive feedback.

If you wish to purchase a radial fan model, pay attention to the brand. "Era". In connection with the design, this type of fan, having even a small capacity, is more efficient in contrast to its axial counterpart.Despite the high cost, such a device instantly justifies it. The basis of the operating mode is the minimum speed and minimum energy costs. Such a system allows for a long time to function in the background for on-duty cleaning. At high humidity in the room the fan starts to work at maximum, so that the air in the room is replaced.

When deciding to purchase a silent fan in the bathroom, you need to consider several important features that affect the productive operation of the device. Properly selected fan for exhaust design should perform, first of all, its primary task - the removal of waste air flow. It is necessary to choose a type of fan so that it fits perfectly in the dimensions of the living space.

In this regard, it is recommended to focus on the following characteristics:

• productivity;
• production (or efficiency of the device) per hour;
• ventilation duct, its shape and parameters;
• quantitative assessment of noise;
• price;
• brand manufacturer;
• profitability.

Based on the silent fan model, the manufacturer must indicate on the package the dimensions of the ventilation duct intended for the device being purchased. In residential areas, such as a private house or apartment, the ventilation system with a pipe, the size of which is one hundred and one hundred and twenty-five millimeters, is most often used. Do not forget to take into account the dimensions of the mounting holes.

That the fan made rotary motions, in production involve the electric motor. Therefore, the occurrence of aerodynamic and mechanical noise is inevitable. The first appears in connection with the movement of the air flow, while the second arises due to mechanical oscillations of the device. A noise level that exceeds thirty-five decibels can cause a negative effect on the mental state of the human body.Manufacturers of silent fans for ventilation design make models whose noise level does not exceed twenty-five decibels. The noise level data can be found in the technical passport of the fan.

Almost all modern models are already equipped with this option. In devices with automatic mode, built-in sensor that responds to movement in space. He reacts instantly, provided that the people in the room create vibrations.

The label of the purchased device, in addition to the place of manufacture, often indicates the place of origin of the company. There are cases when both places do not match. Most experts agree, regardless of the information on the package, you need to pay attention to the responses of consumers.

The cost of the product is influenced by several characteristics: technological properties, the popularity of the brand-manufacturer, and whether the device is equipped with built-in electronic accessories (humidity sensor and timer).The price varies from ten to one hundred dollars, and here the dimensions of the purchased device play an important role. An expensive product does not guarantee a better quality and a longer service life.

After selecting and purchasing the required device, the question arises of connecting a silent fan. This is a simple process, the installation itself does not take much time and effort. It is enough to have minimal knowledge in electricity and skills in construction.

There is a universal algorithm of certain actions that will help you to cope with the installation of the fan quickly and easily.

• If there is ceramic tile on the wall surface, it is necessary to pre-mark the hole for the air duct. Then cut it with the help of the grinder.
• For more comfortable installation, the top fan cover is removed.
• Next, you need to do the output electrical wiring for the fan. To do this, pull the wiring from the wires leading to the switch.
• Using a drill, make grooves so that the necessary wires can be pulled out.

• Install the fan and fasten with bolts.
• Next, you need to connect the wiring to the terminal. It does not matter which terminal to conduct the wires (to the phase or to the ground). Isolate them.
• After that, the upper protective cover is screwed to the original place in the center. It has a protective function, protecting the motor from dust formation. Start the device, and check the correctness of the work.
• Tighten all mounting bolts.

You can connect a silent fan in the bathroom by means of a switch depending on the selected device model. With a switch on the switch - the fan is attached to the wall or ceiling surface at the inlet of the ventilation system. Channel model is mounted directly to the ventilation. A decorative mesh will cover the remaining hole.

A deeper fan in the ventilation system creates less noise.

Distribution box and fan - that's what you need to bring the power cables.It is acceptable to connect a silent fan on the same level with the light switch. But it will be more practical to use a two-button switch.

It is desirable to place the hood on the ceiling simultaneously with the switch. While controlling the household structure, the electrical circuit and the relay must be properly configured. The circuit is responsible for many design functions.

To extend the life of a silent fan, it is recommended to adhere to certain standards. It is necessary to make regular prevention and cleaning of the device. The conception process consists in removing dust and various dirt accumulated on the blades and the ventilation grill.

A clogged ventilation system is cleaned using a mechanical or chemical method. The mechanical method involves the use of brushes or rags made of hard fabric. In the chemical method, a specialized detergent solution is used.The long-abandoned ventilation system must be disassembled and thoroughly cleaned all components.
