What power should the fan have

The heat went: an understandable guide for the choice of a fan

Household appliances are so diverse that the purchase of even such a non.Comprehensive device as a fan can cause questions. Which is better? What to look at when buying and what does not matter? Why one costs 1000 and the other. Ten or even thirty times more expensive?

Ospass fans are those that are popularly called “chamomiles”. The motor sets in motion of the blades, which are fixed on the axis and hidden under the net for safety purposes. The more powerful the engine is, the longer and wider the blades themselves and the higher the fan performance is the volume of air, which it can move in an hour.

The design of the radial fan is a pipe or cylinder with many blades that drive air in a circle (radius) inside the cylinder, and it is pushed out under the influence of centrifugal force. If the axial fan simply moves the air, then the radial creates the pressure and the directed flow. Radial fans, usually a column type, and the column can be either high or very small. There are also portable fans with handles.

Which fan is better to buy for a home

Fans are used for various purposes and when choosing you need to focus on several parameters:

As additional options, manufacturers often offer some functions that successfully complement the work of the device. For example, this may be additional illumination for using the device as a nightlight. The functions of moisturizing, ionization or aromatization improve the properties of the air in the room.

What type of fan operating mechanism is better

By type of performance of the working mechanism, fans are classified into:

The most common are axial models. Structurally, the devices consist of impeller, fixed on the axis, engine and housing on the stand. When the engine is launched, the blades set and drive air masses in a certain direction. For the safety of users, the impeller is closed with a metal grill.

The fan is easy to install and maintain, it is easy to transport it from room to room. For covering larger area, axial fans are supplied with an additional rotation mechanism. The working area increases by several degrees.

Radial fans. This is a newer type of device. The complicated design significantly increases the cost of devices. Outwardly, such fans resemble a column inside which the so.Called “snail” is located from the duct, engine and rotor with shoulder blades.

The air enters the device and due to the centrifugal strength of the engine passes around the circumference and pushes out. The direction of the air masses is provided by a special grill.

Radial devices look like a column that occupies much less space in the room. Basically, this design is used for floor fans, but manufacturers already offer similar models for placement on a table or on the wall. A distinctive feature of radial devices is a quieter job.

Hostless fans

In non.Disabilities, the principle of the turbine is used, which escapes the air and passes it through the aerodynamic ring. The absence of blades provides the highest level of security among all structures. Air masses pass through the frame with a strong uniform stream, producing a small noise.

How to decide on the method of installation of a fan

By purpose and installation method, home fans can be divided into:

In residential premises, floor or desktop models are usually used. The choice dictates the features of the room, since the flooring takes up a lot of space and it is not always possible to install a suitable device. A family with young children needs to think about how to make the device inaccessible to the kids.

Floor fans is difficult to install in small rooms. But such models cover the maximum area with a fusion, so they are used in middle or large rooms. And thanks to the built.In rotary mechanisms, the beneficial effect of devices increases. When choosing, the power and diameter of the blades should be taken into account.

Desktop fans are compact and light. The device can be put on a small surface. Table, window sill, shelf. Table models are not as powerful as flooring, however, to cool a small room or separate zone, they are ideal.


The most powerful ceiling fans are considered. They are able to cover a large area, so the devices are placed in the center of large rooms. This is a stationary design that is often combined with the lamp. Suitable for residential, public and factory premises.

Wall fans are fixed stationary or with the help of clothespins. These devices are not very popular, so in this review they are not considered.


What parameters should you pay attention to when choosing

Power and performance


The power and performance of the fan are inextricably linked to each other and show how large the room can serve this device. But it must be borne in mind that devices with the same power can have a different level of performance. Therefore, when choosing a fan, always pay attention to what area of ​​the room it is calculated.

It is believed that the more powerful the fan is, the louder it works. However, this is not always true. From the instructions you can find out the number of decibels that the device distributes. Usually the noise level is indicated for minimum speeds.

In addition to the noise that the fan creates in the process of work, additional noises caused by vibrations can be observed. Therefore, it is good if you have the opportunity to listen to the fan and understand how much it creates extraneous noise.

Models with a large number of decibels specified in the operation manual cannot be installed in rooms where people rest.

The fan can be controlled using mechanical (cheaper) or electronic (more expensive) control units. Some models are equipped with a control panel, which is very convenient.

Desktop fans

Everything is much easier here. Compact axial models of medium or low power on a low stand. Are local fans. The premises are not particularly “blown”, but good in close proximity, being hoisted on the table or bedside table.

Fans with a rather large “wingspan”. However, by virtue of the method of placement, they do not occupy an extra place in the room, you won’t stumble about them, you won’t drop (unless, of course, the neighbors do not get on top). Ceiling fans are best suited for the bedroom as a supercultural source of coolness combined with a chandelier. Block of lamps either immediately in the kit or maintaining an optional reinforcement.


Other types of fans are also found. For example, wall. Here are only their very specific ways to attach few people will be interesting at home. There are table “clothespins” with power supply from USB. This is generally from another “opera”. Computer accessories. Finally, there are awkward models with a turbine. The price tag is sky.High, there are no special advantages, except for space design. And they are not silent at all.

The model is controlled from the electronic panel, and in addition to the remote control.

This is the quietest flooring for home among models with smart control. The device is integrated into the system of a smart home and controlled from a smartphone or PC. There is an alternative power source. In the form of a battery.

  • Smart technologies.
  • Management and settings at a distance.
  • Minimum background noise at maximum speed.
  • The possibility of programming modes.
  • Tilt up to 120 degrees.
  • Autonomous work up to 16 hours.
  • Stylish design.


Most fans have such a mechanism. They have a impeller familiar to everyone, which rotates.

When choosing an axial model, pay attention to the size of the blades. The larger they are, the more powerful they will create. Three wide blades are better than five thin. But if a strong blow is not needed, you can choose thin-lobed models-they look more interesting.


Such fans are also called column. Outwardly they resemble an air cleaner or heater, although they perform completely different functions.

The device works on a completely different principle. The air entering the rotor is untwisted inside at the expense of centrifugal force and pushed through the holes due to the pressure difference.

Radial fans work noticeably quieter, occupy much less space.


These are very unusual fans that are a hollow ring (or oval). Inside the case is a powerful turbine that escaces and blews air through the cracks. Such a device looks futuristic and will decorate any interior.

Number of speeds

Contrary to common opinion, a large number of speeds are not an important advantage. For a regular home fan, as a rule, a standard set (3 speeds) is always quite enough. However, sometimes manufacturers make an exception, and equip the axial fans (with an air screw) with a switch at 4-8 speeds.

Radial (column) and non.Disabilities, on the contrary, often not only have a wide range of speed modes (up to 10 pcs.) but also supplemented by smooth adjustment, which allows you to set the most comfortable mode of operation.

All about the floor system of ventilation:

First of all, it is worth understanding how this system works. After all, it does not cool the air, no matter how strange it seemed to you. It’s all about the features of our body.

When the room is hot, the body is cooled due to sweat secretions. Drops protruding on the skin. Accelerating the flows of air, albeit hot, a device with a ventilation function simply helps this moisture to evaporate faster. Thus, the effect of cooling is achieved.

Additional functions

When choosing a floor fan, you will face the fact that almost all models are equipped with various additional options. They greatly facilitate management and make the operation of climate equipment more comfortable.

  • Remote control. With it, you can turn on and off the device, switch the operating modes.
  • LCD display. The display with current information simplifies management and setting up work.
  • Timer. Can configure the fan time. Especially relevant during falling asleep for automatic disconnection, so as not to work all night.
  • Management through Wi-Fi and Bluetooth. In the presence of this option, you can control the device from a computer or smartphone.
  • Ionization. Satuns the air with negative ions, the air is cleaned of microbes, it becomes easier to breathe.
  • Air moisture. Using a built.In ultrasound evaporator, increases humidity in the room.
  • Motion Sensor. Turns on the fan when someone enters the room and turns off if the room is empty.


With the help of this option, the fan creates the most comfortable microclimate as possible, maintaining humidity normally. It is important to take into account that the presence of this option affects the price of the model.

Using the ionization option, the air is filled with negatively charged ions, which, in general, favorably affects the microclimate in the room.
