Installation of centrifugal fans

When installing centrifugal fans, it is important to try to give the fan the best possible conditions in order to be able to provide the desired performance. Below is some advice on the way.


When installing, it is important to ensure that the fans are not subjected to a counter-rotating flow at the inlet, as this can lead to significant performance losses.

The inlets should be as free as possible to prevent reduced performance. Collapsed elastic intake spigots or pipe bends just before the fan should be avoided, especially for cylindrical intake types.
Free outlets should be via a pipe with a length of at least 3 x D (D = intake diameter).

Our centrifugal fans can be used in the temperature range -25 degrees to +115 degrees C.
Outside this range, special grease, special surface treatments, cooling discs etc. may be needed. Please inform us of your operating data and we can help you.

EX Environments

For explosion-proof designs, the “cut-off”, inlet cone and impeller wheels are made of AlMg3, which in the absence of steel does not cause sparks due to friction or impact.
On request, the fans can be supplied with a marine brass spark arrestor which in contact with mild steel does not give rise to friction or impact arcs.
For high safety requirements – especially to avoid dust explosions, the lining can be made of tin. Its melting point is so low that even ignition due to hot surfaces becomes unlikely.
