Over the last few years the need for more quiet impellers has been the driving
force of most new impeller types from Multi-Wing. The result has been our new
series of sickle shaped impellers, so far to fit the Z and W hub systems. The
series has proven its capability to perform well at the lowest possible noise
emission, and is already used in many applications from mobile radiators to
refrigeration systems.
The latest new profile is designed for the H type
hub systems, and is the smallest in the sickle series. It comes in 6, 8, 10, 12
and 14 blade configurations covering diameters from 317mm to 564mm. The blade is
available for both clockwise and counter-clockwise rotation and in pitch angles
ranging from 25° to 50° with 5° increment.
