Domestic fans allow providing sufficient comfort in the room if standard ventilation does not cope with this obligation. Such devices are suitable for apartments, small industrial premises or cottages. Modern mechanisms are equipped with additional functionality, although they can not compete for the effectiveness of air conditioning systems. Nevertheless, their cost is much lower, and the scope of use does not depend on one place, since they are maximally adapted for transportation, storage and simple manual transportation. Consider the features of these units.
Criterias of choice
The main parameters that should be considered when choosing household fans:
- Power unit. The performance of the device depends on this parameter. Accordingly, the larger the area of the room, the higher this indicator should be. It is worth noting that this recommendation is relevant for floor or wall models; the size of the blades plays a decisive role in the desktop version.
- Noisiness. This indicator affects the degree of comfort of use of the device, especially at night or in rooms with small children. The optimal indicator should not exceed 40 dB.
- Motor. This unit is equipped with special bushings or ball bearings. In the first case, a household fan produces less noise and has greater performance.
- Additional options. For a separate price, the devices are equipped with a backlight, timer, display or air ionizer.
Axial Domestic Fans
In such modifications, air moves under the influence of an impeller rotating around its own axis. The main mechanism is fixed on the sleeve in the form of blades, they are placed at a certain angle. During operation, the propeller captures the air mass and transports it in the direction of axis rotation.
The axial household fan is suitable for operation in any type of residential area, as it is characterized by low noise and medium power. Among the advantages - high efficiency, reasonable price, reduced noise. Popular models: Maico, Soler & Palau, Vortice, Systemair.
Centrifugal Modifications
These units are equipped with a rotor driven by an electric motor. It consists of spiral-shaped blades, rotating in such a way that the air moves and contracts, supplied radially from the central part.
Once in the case, the mass is transported into a special hole through the "snail". Often household centrifugal fans are used in smoke removal and conditioning systems, air-heating units, and technological structures.
Floor units
Such modifications are installed indoors and provide movement of air masses, creating comfortable conditions and freshness in the room. The compact and practical option is optimally suited for both office and home, during periods of elevated air temperature.
In addition, there are floor-standing counterparts designed to service large and industrial premises. They are distinguished by an increased power indicator, are equipped with automatic transformers, can change the speed of rotation, have a regulator of the intensity of work.
Duct Domestic Fans
Such mechanisms are designed for air ducts and are divided into several categories:
- Models for round ducts of the supply and exhaust system.
- Versions for rectangular placement.
- Analogs for square nests.
The devices have a similar mode of operation, a robust case, a high rate of performance. Domestic duct fans do not need special additional maintenance. The presence of high-strength materials allows for a long working period in time.
Advantages: high performance and small dimensions. Compared to wall-mounted counterparts, this equipment has a higher power rating. Devices do not require frequent maintenance, have a minimum noise level. Manufacturers: Soler & Palau, Systemair, Ostberg.
Wall fixtures
Using the devices in question makes it possible to clean the room of stale air, excess moisture, dust and impurities in the air. The unit sensor allows you to automate the operation of the device as much as possible, are made of plastic, often equipped with additional devices.
Wall-mounted household exhaust fans are usually mounted in the upper part of the wall partition, which eliminates the ingress of splashes and other foreign substances. Some modifications are equipped with protective panels. Popular brands: Maico, Elicent, Vortice, Soler & Palau Silent Design. The main advantages of wall-mounted household fans are reduced noise, versatility, the presence of additional devices that increase the usability of the device.
Ceiling and roof-shaped analogues
Modifications of this type create pleasant vibrations of the air, simply mixing it with their blades. It is best to combine them with air-conditioning systems, which will achieve the creation of the optimum room temperature at the lowest cost. Some variations are equipped with a backlight.
Domestic fans with or without a valve with high, medium or low aerodynamic parameters are mounted on the roof. Due to the fact that the units are installed outside the room, they significantly save space and do not make noise. The main use of the models under consideration is smoke removal and ventilation cleaning from other harmful and dangerous implants. Feature - reliable design, high performance, long period of operation.
Nuances
Among other household fans, the following modifications can be noted:
- Fireplace models. They serve to remove exhaust gases, mounted on a chimney.
- Kitchen counterparts are focused on providing continuous extraction from a room where a large amount of burning, smoke and soot accumulates in the air.
- Noise-proof versions have a housing with additional insulation, which guarantees a reduced noise level during operation of the device.
- Explosion-proof products are focused on the output of air masses saturated with explosive gases.
