Fans are often in use for a very long time before they realize that the unit may be heavily soiled. How a fan is to be cleaned, we have summarized in the following guide for you.
Different versions of fans
Fans are a low-cost alternative to air conditioning when it is particularly hot in summer. There are different types of fans:
- the ceiling fan
- different versions of standing fans
- fans, which are fixed to the wall
If a room needs to be cooled with a fan, all three versions have their advantages and disadvantages. We also explain if a fan may work more efficiently if a wet towel is placed over the fan.
Fans are true dirt collectors
As far as cleaning is concerned, there is an important difference between the different versions. Floor and wall fans are designed differently than ceiling fans. We refer here to floor and wall fans, since these devices with the most dirt is to be expected.
The fan draws in the air from behind and blows it forward. Both fan versions are provided with a protective grid. Dust and dirt particles that are transported with the air are already collected in this protective grid. The blades of the fan also pollute significantly over time. In particular, at the "air-cutting side" can stick a veritable dirt layer.
Cleaning the fan: Removing the front grille
To clean the fan, the front and rear grille must be removed. Either they are held together with movable hooks or a circumferential plastic band. Simply disengage the hooks or pull the tape forwards, then you can remove the front grille half already.
Removing the airfoil
The rotor blade is centered on a kind of square, so that it is fixed. The rotor blade is therefore simply pulled off to the front. But before that happens, you first have to unscrew the fixing nut. This sits in the middle of the front of the rotor blade. Attention! This nut is usually turned against the usual thread direction (right-hand thread) to the left (left-hand thread).
Remove the rear guard from the fan and clean it
Behind the rotor blade, another nut is now visible on the main shaft. This fixes the rear grille half. This is fixed by three or two pins through which the grid must be inserted when it is put on. Now you can clean both the protective grille and the wind vane. The subsequent assembly takes place in reverse order.Tips & TricksThe protective grids are often made of metal. Please do not be tempted to work the grid with a wire brush, for example. This will also damage the paint. The air is also air moisture, so transported water. This water can cause the grate to rust more quickly if the paint layer has been damaged.
