What is an air supply fan?

As the name suggests, a air supply fan improves the oxygen levels by bringing inside healthy and fresh outside air. An air supply fan increases the efficiency of the pre-existing ventilation.


Into which room do you install a air supply fan?

You must install a suitable air supply fan in a room where the ventilation needs to be improved. You can install an air supply fan into every room, or just to the ones that have ventilation problems. For example in homes, bedrooms are the most important rooms to have good air quality to facilitate good sleep and well-being.


What exactly is supply air?

It is the incoming fresh air which replaces the old air that exits typically from the kitchen, bathroom etc. It is very important that the incoming fresh air is pre-heated and filtered.


Will an air supply fan interfere with the buildings existing ventilation system?

No. Air supply fans do not interfere with any existing ventilation system. However, it is required in apartment building as well as other buildings that supply air valves must not cause positive air pressure indoors. This is why all Mobair products have been designed to prevent this from happening, and the authorities have approved all Mobair systems.
