Centrifugal Fans Backward Curve

These Fans use Backward Curved Impellers made of Steel or Engineering Plastics. The impellers are press fitted on the External Rotor Motor and dynamically Balanced in two planes. Backward Curved Fans can be used with or without scroll Housing, and find its application in sucking operations, and where static required at Fan Inlet is high.

Backward Curved fans Range From :

Impeller Diam.
:
190 to 225 mm
Air Flow
:
500 to 1000 m3/hr
Input Voltage
:
110, 220, 440 V AC (50 & 60 Hz.)
Power Input
:
60 to 300W

NOTE : Motors with CE Mark and confirm to EN 60335-1 standards.
