A hallmark of a bathroom or kitchen is high humidity or odors. Dampness causes the active development of mold and fungi, which can cause various diseases in humans. And unpleasant odors can be absorbed into clothes and furniture, disrupting the comfortable existence of a person. You can solve this problem with silent fans. In the article, we will consider the types of such devices, models and installation features.
What is the hood for
Everyone understands that there must be an exhaust hood in the bathroom or kitchen. This is important not only in everyday life, but also when carrying out repair or finishing work - in no case should the ventilation hole be closed.
The absence of a hood or its poor performance can lead to an increase in humidity in the roomand the appearance of unpleasant signs of this:
- condensation on walls and mirrors;
- constantly damp towels, wet clothes and slow drying things;
- characteristic black mold spots on furniture, wall and ceiling corners, doors;
- appearance of an unpleasant smell of dampness.
The appearance of such signs leads not only to the deterioration of the interior of the room, but also causes some diseases.
The natural movement of air flows through the hood is not always able to cope with the above problems. Over time, air ducts become clogged and clogged, reducing their efficiency.
The output in this case is the installation of forced exhaust with a fan - the device ensures good system performance for a long time. With the right choice, a silent exhaust fan will solve your problems.
When choosing a model, you need to be guided by some criteria - they will be described below: performance; comfort of operation; profitability; safe use.
Performance and economy
One of the most important characteristics of a fan is its performance - the efficiency of the device will depend on its level.
In order to correctly determine this indicator, you need to calculate the volume of the room in which the silent fan will be installed. This parameter is found by multiplying the geometric parameters of the room: height, width and length. same performanceis calculated by multiplying the volume of the room by the air exchange rate.
Regulatory requirements for installing a silent fan in a room require that the calculation also use data on the number of permanently present in the room to ensure optimal air exchange.
In order to reduce the cost of maintaining the fan, including the cost of electricity, when buying, it is necessary to give preference to modern devices. They are equipped with special timers and switches that regulate the operation of the device in various modes.
Comfort and safety
To avoid discomfort during the operation of the device, when buying, you must take into account the indicator that determines the noise level created by the so-called silent fans.
During operation, these devices maintain fairly low noise levels, not exceeding thirty-five decibels. Such a parameter value is not capable of causing discomfort to those present, and the device will be almost invisible.
The issues of safe operation of such equipment should be given close attention, especially when installed in a bathroom (a room with high humidity). The design of the device housing must ensure that moisture cannot enter the device. Otherwise, there is a high probability that a short circuit will occur.
What characteristics to consider when choosing
Choosing silentfan for a bathroom or other room, the following criteria should be considered:
- noise level of the device - ideally should not exceed 20 dB;
- motor power;
- working voltage and frequency;
- impeller pressure;
- performance and operating temperature;
- product dimensions.
You also need to know that the manufacturer in the technical documentation provides two parameters: the landing diameter of the device and the size of the impeller itself.
Many believe that the power of the fan affects the performance of its noise. Experts say that this is not so. In modern models, there are design features - special noise reduction systems that help improve this parameter. In addition, an important role is played by the material from which the case is made.
Model selection
In order to choose the optimal device, you need to know some subtleties.
Experts advise the following:
- In the kitchen, it is better to choose fans with a maximum power not exceeding 2 kW. This is quite enough to keep the performance of the device within 80 cubic meters. meters per hour. In this case, the noise level should correspond to the mark of 25 dB. The optimal impeller diameter is 100 mm. A silent fan should have additional functions in the form of a timer and a hydrostat.
- For apartments in apartment buildings and bathrooms, it is better to choose models with a check valve. Such a devicewill prevent unpleasant odors from neighbors.
- From the point of view of safety during operation, experts advise choosing a fan with a moisture-proof and splash-proof casing.
- In the bathroom, it is better to install a silent duct fan equipped with a humidity sensor. The maximum power indicator should not be less than 3 kW.
- Experts recognize the best solution as models with special built-in sensors that turn on the fan when the humidity rises to a predetermined level. After reaching the optimal value, the device turns off.
Some modern models of exhaust fans have integrated lights, which allows designers to seamlessly fit such a device into the interior.
Barrier fans
Quiet fan with non-return valve, which serves as a barrier to foreign odors, equipped with a fairly simple mechanism that can prevent exhausted air from entering back.
These devices are made of plastic or stainless steel.
Structurally, they consist of the following parts:
- frame;
- two flaps and a pin on which the flaps are mounted;
- air intake grille;
- engine;
- aerodynamic impeller;
- vibration dampening inserts.
The air in such a device moves only in one direction, held by closed flaps. When the fan is turned on, the flaps move underthe action of the air flow, sucking it in constantly during operation. When the power is turned off, the flaps slam shut, preventing the air from moving back.
Types and models of fans
Silent fans for extracting in the bathroom or in other rooms are divided into types according to design features.
Devices of this type are:
- Axial exhaust fans. They consist of a cylindrical body with an engine on which the blades are mounted. At the outlet is a manifold that reduces noise and improves aerodynamic performance. Productivity - more than 100 m3 per hour, easy to install. This type includes: Blauberg Sileo 125T, Soler&Palau SILENT 100, Electrolux EAF, Vents 100. Silent fans of this group are considered the most efficient.
- Radial exhaust fans. The air moves radially, the blades can be located both back and forward. The first option is better in terms of efficiency and noise. In this category, it is worth noting such models as Systemair CBF100, Soler & Palau Silentub-200, Design S/5210612300, Soler&Palau EcoAir.
- Centrifugal exhaust fans. They are the best option for small rooms with an area of \u200b\u200bless than 15 square meters. Quite powerful and quiet. When installing devices with a rectangular cross section, an anemostat is required (with a round cross section, it is not necessary). The most demanded devices of this group are Soler&Palau EBB-250 NS, Cata CB-100 Plus.
- Duct fans. Such devices are installed in the duct channel. Compact, suitable for installation in bathrooms and other small spaces. The most popular in this series are "VENTS 100 VKO", SILENT 790-900 is the best silent duct fan.
- Roof fans. They are installed directly on the roof, they consist of a base, a confuser and a casing. There are centrifugal and axial. The most in demand in this group are devices of the brand Systemair.
Fans with humidity sensor
Such devices are installed in rooms with high humidity (bathrooms). They have different controls:
- mechanical - the fan is equipped with a timer or hydrostat-sensor, on which a person sets the necessary operating modes, the hood functions only when the set humidity value is exceeded.
- automatic - works according to the set modes, very economical devices.
Design features allow you to install models of silent fans in the bathroom on the ceiling or wall. Moisture-resistant materials are used in the production.
