Extraction Fans

 

Extractor Fans
To control the removal of moisture and at the same time minimise heat loss in the kitchen and bathroom, the solution is an extractor fan fitted to a window, ceiling, outside wall or a ducted system.  Extractors come in a variety of sizes to meet the needs of most applications and choosing the right one is dependant on a number of factors.  Careful consideration should be given to the extractor's ability in removing a measured amount of air in a given amount of time in relation to the room's size.  Rushing out and purchasing a fan labelled  'Bathroom fan', could prove to be an unwise move.

Centrifugal Fans

Centrifugal fans are suitable for greater airflow resistance, that is, designed to be used within a ducted system.

 

 



Axial Fans

Axial Fans are the type designed to fit on a panel, wall mounted or on a window panel. They are designed to move air over a short distance. They would not normally be used in a ducted system.

With an extractor fitted, doors closed, the house fitted with a good draught proofing system and the air being extracted from the room at a measured rate, consideration should be given to air replacement.  'Short Circuiting' is a situation, where the air that is being removed, cannot be replaced at the same rate, resulting in the extractor loosing its ability to extract and function effectively.  To overcome this problem, adequate air vents should be installed, which will allow constant air supply into the house/rooms, while the extractor takes the unwanted air outdoors.
