Centrifugal roof exhaust fan

This centrifugal downblast roof exhaust fan uses direct drive and arrives fully assembled. It runs on 115V AC single phase power with a 1/8 hp motor. The unit delivers 431 cfm of exhaust airflow at .000 in static pressure and is rated for clean air applications.

Clean air, low-static installations

It suits roof mounting where clean air must be moved against minimal resistance up to 1/4 in wc static pressure. Buyers needing higher static pressure capability, high-efficiency motor ratings, or configurations for contaminated airstreams should look at other models.

11 in wheel diameter

The 11 in wheel diameter determines the airflow and pressure performance of this direct drive assembly. Match this dimension to your system design requirements to confirm the fan meets the necessary duty point.

Questions about this item

What airflow can I expect from the 431 cfm rating once the fan is installed on a roof?

The 431 cfm figure is measured at zero static pressure. Actual airflow will drop once ductwork, roof curbs or filters add resistance, and the unit is rated for a maximum of 1/4 in wc static pressure.

How does the 115V single-phase supply limit the motor's performance?

The 1/8 hp motor runs on standard 115V AC single-phase power, so it plugs into a typical household circuit. That voltage caps the motor at its nameplate horsepower and the 431 cfm free-air rating.

Will the 22-inch square base fit my existing roof curb or opening?

The fan base is 22 in long by 22 in wide with a square shape. Verify your curb inside dimensions match or exceed 22 in on each side before ordering.
