Product Profile of Centrifugal Fans Backward Curved
VBM Enterprises manufactures Centrifugal Fan Backward Curve. VBM Enterprises offers External Rotor Motors, Axial Flow Fans, Centrifugal Blowers, etc. The Centrifugal 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. This Centrifugal Fan Backward Curve can be used with or without scroll housing, and find its application in sucking operations, and where static required at fan inlet is high.
Centrifugal Fan Backward Curve range from:
Impeller Diameter: 190 to 250 mm
Air Flow: 500 to 1500 m3/hr
Input Voltage: 110, 220, 440 V AC [50 & 60 Hz.]
Power Input: 60 to 300W
The motors are CE Marked and confirm to EN 60335-1 standards.
Applications of the Centrifugal Fan Backward Curve:
Thyristor and Electronic Panel Cooling
Roof Extractors and Kitchen Hoods
Room Air Filters/Cleaners
Applications with relatively high static pressure at the Inlet of the Fan
