ELECTRIC POWERED VENTILATOR

The efficient design of these fans includes  propeller which produces amuch greater intake of air into the vacuum side, eliminates turbulence at the tips, and provides a high velocity screw action that sweeps air back over the motor.  HF series are higher-powered units that run at 3,450 RPM for greater air movement. The HF series are also available with explosion proof motors for hazardous locations use.
