TPI Shutter Mounted Exhaust Fan Model - 20 inches CE-20-DS
TPI Corporation offers three types of direct drive exhaust fans. Each type comes in the same 8 fan sizes (see Customer Images for a table).
- a guard mounted fan includes a motor & propeller attached to a spiral wire blade guard with an electrical box, pull switch, and rubber mounting bumpers,
- a shutter mounted fan is a combination of two products: a guard mounted fan, and an external shutter.
- a venturi mounted fan is a guard mounted fan on a sheet metal frame, but no shutter. The outer frame edges are bent toward the inside at 90 degrees for strength. "Venturi" is a flaring of the sheet metal away from the fan, to direct the air flow. A venturi mounted fan costs about 25% more than a shutter mounted fan, and it doesn't even include a shutter.
