Bathroom is a closed and moist place. This area essentially needs a fan which can extract the moist and stale air out of it. Exhaust fans are used in most of the bathrooms to control moisture and provide proper ventilation.

Bathroom exhaust fan are of two types. One is the propeller or axial fan and the other is the centrifugal fan. The propeller or axial fan is same as the fan which we use regularly in our homes. It rotates and moves the air by moving circularly. There is no requirement of the large pressure in moving in the circular motion. Hence these fans are affordable and efficient.

The other type of fan is the centrifugal fans which are not accepted as the axial fan for the bathrooms. The centrifugal force mostly used to draw the air out of the radial vanes in the plates. So it is easy to fit these fans on your own as it comes with the fitting instructions.

The function of an extractor fan is that it extracts the dry air out when it is turned on. These fans have blades or impellers attached to the electric motor. When the motor starts rotating, it pulls the air and disposes out of the grille.

The axial fan and the centrifugal fan can be mounted in two places. You can mount it on the window but you’ll need to make a hole in the glass. For this you will require a special tool for cutting holes. But you can also mount it on the wall. You need to have a drill to make the hole in the wall. Depending upon the thickness of the wall, it can take long time to be drilled. It is also very tedious job as you need to make a force on the drill.

Some fans have automatic cut-off switches. When the humidity in the bathroom decreases, it switches off automatically and when the humidity increases, it switches on again.

If you wish that your fan should keep working at an optimum capacity then remember to maintain it daily.

A fuse-spur is connected in most of the extractor fans which is normally fitted outside the bathroom fitting. In order to work properly, the extractor fan should be placed perfectly. The location should be chosen in such a way that the extractor fan will replace the fresh air by drawing the stale air.
