CENTRIFUGAL FANS BACKWARD CURVED

VBM Enterprises manufactures Centrifugal Fan Backward Curved. 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. It can be used with or without scroll housing, and find its application in sucking operations, and where static required at fan inlet is high. Range in sizes from: impeller dia - 190 to 225 mm; airflow - 500 to 1000 m3/hr; input voltage - 110, 220, 440 V AC (50 and 60 Hz); power input - 60 to 300 W. Typical applications: thyristor and electronic panel cooling; roof extractors and kitchen hoods; room air filters/ cleaners; and applications with relatively high static pressure at the inlet of the fan.
