Roof exhaust fan for clean-air applications

The Dayton 16D527 is a centrifugal downblast roof exhaust fan built for clean-air environments. It arrives fully assembled with the motor and drive package included. Direct-drive construction removes belts and pulleys from the maintenance schedule. The unit operates on 115 V AC single-phase power.

Installations needing up to 203 cfm at zero static

This fan suits roofs where exhaust volumes near 203 cfm at 0.000 in SP are sufficient and static pressure stays at or below 1/4 in wc. It is not intended for high-static-pressure duct systems or for air streams containing grease, dust, or corrosive contaminants. Buyers who need higher airflow or pressure ratings should look at larger-capacity models.

1/60 hp direct-drive motor on 115 V AC

The 1/60 hp motor runs directly on 115 V AC single-phase supply without a belt drive. This low-horsepower design keeps electrical draw minimal while delivering the rated 203 cfm at free air. Confirm that the available circuit and the required static pressure match these specifications before purchase.

Questions about this item

How much heat or power does the 1/60 hp motor add during continuous operation?

The 1/60 hp motor draws 115V AC single-phase power; exact heat output isn't published but the low horsepower keeps energy use minimal.

What roof opening and curb does the 17 in square base need?

The 17 in square base requires a matching roof curb and a clear opening sized to the curb dimensions for secure mounting.

Will the 203 cfm at .000 in SP overwhelm older ductwork sized for smaller fans?

At 203 cfm free-air flow the fan suits light exhaust needs; check existing duct static pressure to confirm compatibility.
