Damper - Parallel Blade Inlet Box Damper
When partially closed the inlet box damper pre-spins the air in the direction of wheel rotation,
resulting in a savings in horsepower at reduced loads.

Fins on Wheel Backplate
Fins on backplate reduce the thrust load on the bearings. Fins can create a negative pressure behind
the wheel to draw air into the fan through the shaft hole in the housing. Helps reduce the possibility
of leakage of the airstream to atmosphere.
