Direct-drive centrifugal roof exhaust fan

This Dayton 5DVR7 is a downblast centrifugal roof exhaust fan with direct-drive construction and an 8-inch wheel. It ships assembled and includes the motor and drive package. The unit runs on 115V AC single-phase power and uses a 1/20 hp motor to deliver 495 cfm at .000 in static pressure.

Installers needing a compact clean-air roof

The square 17-by-17-inch base and direct-drive layout suit roofs where belt maintenance is impractical and the air stream is clean. Maximum static pressure of 1/2 in wc limits use to low-resistance duct runs. Installations that require high-static-pressure capability, larger airflow volumes or belt-driven serviceability should look at other models.

495 cfm at zero static pressure

This airflow rating at .000 in wc is the key figure for sizing the fan to the ventilation load. If the system has any measurable duct resistance, the delivered airflow will drop below this value and a higher-capacity unit will be required.

Questions about this item

What is the maximum static pressure this downblast vent can handle before airflow drops off?

The unit is rated for a maximum static pressure of 1/2 in wc, which is the limit where sustained airflow begins to fall.

How much electrical power does the motor draw when the fan runs continuously?

The direct-drive motor is rated at 1/20 hp on 115 V AC single-phase power.

What roof opening or curb size is needed to mount the 17 in square base?

The base measures 17 in by 17 in square, so the roof curb or opening must accommodate that footprint.
