11-inch downblast exhaust fan

The Dayton 5DVR9 is a centrifugal roof-mounted exhaust fan with an 11-inch wheel diameter and direct-drive motor assembly. It operates on 115V AC single-phase power with a 1/6 hp motor rated at 0.09 BHP. The unit delivers 966 cfm airflow at zero static pressure.

Suited for clean-air roof ventilation

This fan fits commercial or residential roof installations needing direct-drive simplicity and 966 cfm capacity for clean-air environments. It is not for high-static-pressure duct systems, grease-laden kitchen exhaust, or hazardous-location airflow. Buyers needing belt-drive serviceability or larger wheel diameters should look elsewhere.

Pre-assembled with motor and drive package

The unit ships fully assembled and includes the motor and drive package, eliminating field assembly of those components. Square 22-inch base dimensions simplify roof curb alignment. No variable-speed control, disconnect switch, or specialty coatings are included.

Questions about this item

What roof opening size is required for the 22 in square base?

The fan base measures 22 in by 22 in square; a roof curb or opening that matches those outside dimensions is needed for secure mounting.

Can the 115V single-phase motor run on a standard household circuit?

Yes, the motor is rated for 115V AC single-phase power, compatible with ordinary residential wiring and a 15 A breaker.

How can I confirm the fan is moving the rated 966 cfm after installation?

Measure airflow at the discharge with a calibrated balometer or traverse the duct at .000 in static pressure; the reading should be close to 966 cfm.
