This TPI Corporation CE 30-DS single phase 30-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.

Industrial fans are used in workplace environments to exhaust fumes or direct air flow. Most industrial fans have coated metal parts and lubricated motors that are permanently sealed to help protect against environmental hazards, such as dirt and airborne debris or corrosive fumes. They can have fan blade cages that meet workplace safety standards, as well as a variety of mounting mechanisms for precise placement to direct large volumes of air flow. Electronic circuitry for industrial fans matches the power specifications found in the workplace and provides the initial torque needed to start up a large blade fan. Industrial fans are used in warehouses, gyms, and other commercial environments to ventilate spaces and to circulate air.
TPI Corporation manufactures industrial and commercial electrical heaters, process heat ovens, ventilation products and fans, lighting equipment, and thermostatic controls. The company, founded in 1950, is headquartered in Johnson City, TN.
