In order to ensure the circulation of air in the room, it is not enough to put any fan simply. Different ventilation systems are installed depending on the volume and type of room. Let’s start dealing with these devices dividing them into three groups: the first is exhaust axial fans, the second is the duct fans and the third is centrifugal. All of them are mainly distinguished by the location of the engine.
Centrifugal fans are not at all similar to similar devices that are familiar to us and have the shape of boxes, duct fans join the duct and they are inside the ventilation system. The axial ones, which are the simplest type of these devices, are inserted into the duct channel, but this does not mean at all that it automatically turns into channel. In order to choose really the device that will perform the functions laid on it, do not focus exclusively on the appearance.
How most often the choice of fans for an apartment or house? The owner of the room goes to the store and selects the device that will most fit into the interior and have as many functions as possible. Most often, the choice will fall on a regular axial fan, in which various sensors are built, such as movements or column with measuring temperature and humidity. But if you are really faced with the task of ensuring a flow of fresh air indoors, then you need to approach the choice much more serious.
The most common are axial fans. They are the cheapest. But they do not have enough power to push the air through the ventilation shaft. Therefore, such fans can only be placed if the duct leaves through the wall, or on the upper floors, where the roof is going on the next level. In other cases, it is strictly recommended to install channel or centrifugal devices. An important indicator is performance. By this abstruse word, this refers to the volume of air that changes the fan in one hour of time.
Also, when choosing a fan, the role itself will play the room from which you need to pump out air. For the kitchen, you need a device where it does not stick fat on the blades. If the fan is installed in the bathroom, then you need to buy the model that has appropriate engine protection. Also consider the place where you want to install the fan, it can be hidden in the duct or under the suspended ceiling. Do not forget to find out the size of the ventilation shaft to choose a fan that can be installed inside.
