The F series is the perfect combination of a low noise, high output design.  The larger sizes are perfect for your bigger requirements including machine cooling and larger spaces.  A hazardous location motor listed for Class 1, Group D on the F series is also available.  The efficient design of these fans includes Super Vac's patented propeller which produces a much 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.
