Product details:

This TPI Corporation CE 18-DS single phase 18-inch diameter direct drive exhaust fan has a built-in shutter mechanism and is suitable for ventilating a building to the outside. The blade assembly (consisting of a steel hub and spider) holds the fan head's three aluminum paddles, which are enclosed by front steel spiral wire guards for strength. The built-in shutter mechanism allows the fan to be installed without external framing, and the self-closing shutters protect the fan from rain and snow when not in operation. The permanent split capacitor (PSC) motor provides both starting torque and the ability to run at variable speeds. The motor of the TPI direct drive exhaust fan is totally enclosed, making it suitable for use in conditions that standard, unenclosed motors are not, such as in the presence of dust or other airborne debris.
