Fan Performance
Coupled with the above fan diameters the speed controllable motor allows the exact
performance required to be obtained.

Impellers
A unique high efficiency aerofoil section blade. The Fläkt Woods impellers are all high
pressure die cast to offer thin aerofoil sections for low generation of noise.
Every cast aluminum component is X-r ay examined using Real Time Radiography inspection
prior to assembly. The maximum pitch angles shown allow for speed control by frequency
inverter.

Motors
All motors are totally enclosed airstream rated class F insulation. Constructed from
aluminum as standard with special ‘T’ slot fixings. Suitable for horizontal through to vertical
shaft operation.
Supplied IP55 with removable drain plugs.
These motors are suitable for inverter speed control down to 20% of full speed.
