Centrifugal Downblast Roof Exhaust Fan

The Dayton 5DVR8 is a direct-drive centrifugal downblast roof exhaust fan rated at 1/15 hp and 115V AC single-phase. It delivers 768 cfm at .000 in static pressure for clean-air ventilation on rooftops. Assembly arrives complete with motor and drive package.

Roof Opening and Electrical Supply

Verify the roof curb or opening accommodates a square base measuring 19 in by 17 in before ordering. Confirm the circuit provides 115V AC single-phase power and that the system static pressure does not exceed 5/8 in wc. This model is not rated for high-static-pressure applications.

All-Metal Construction and Roof Mounting

The square metal base and direct-drive wheel mount directly to the roof curb without a separate base plate. Direct drive eliminates belt maintenance while the downblast discharge directs exhaust away from the roof surface. Motor and drive components are factory-installed for immediate operation.

Questions about this item

What comes in the box with the Dayton 5DVR8 and what must be purchased separately?

The unit ships assembled with the motor and drive package included. No separate motor or drive kit is required for installation.

How do I choose between the available versions or capacities of this roof exhaust fan?

This model is a single configuration with a 1/15 hp motor, 115V AC single-phase power, and 768 cfm airflow at .000 in static pressure.

What does the 768 cfm airflow rating mean when the fan is installed on a real roof?

That figure is measured at zero static pressure; actual airflow will drop once ductwork and roof resistance are added, up to the maximum 5/8 in wc rating.
