Downblast roof exhaust fan

The Dayton 16D529 is a centrifugal downblast roof exhaust fan designed to vent clean air from commercial or residential buildings. It operates on 115V AC single-phase power with a direct-drive motor rated at 1/30 hp. The unit arrives fully assembled and includes the motor and drive package for immediate installation on a roof curb.

Suited for low-static pressure clean-air exhaust

This fan suits installers needing a direct-drive unit for clean-air exhaust at 374 cfm with zero static pressure. It is not for buyers who need high-static pressure capability or a high-efficiency motor. The 3/4 in wc maximum static pressure limits use in ducted systems with significant resistance. Buyers requiring belt-drive configurations or larger wheel diameters should look at something else.

374 cfm airflow at zero static pressure

The decisive specification is the exhaust airflow of 374 cfm measured at .000 in SP. This figure determines whether the fan can meet the ventilation demand of the space served. Verify the required airflow against this rating before purchase. The 8 in wheel diameter and 17 in square base define the roof curb compatibility.

Questions about this item

Does the Dayton 16D529 arrive fully assembled with the motor and drive package included, or do I need to source them separately?

The unit ships assembled and includes both the motor and the drive package, so no additional components are required for installation.

Should I select the 115 V single-phase 1/30 hp version for a standard residential circuit, or is another voltage offered?

The fan is available only in a 115 V AC single-phase configuration with a 1/30 hp motor, matching typical household wiring.

What does the 374 cfm rating at 0.000 in SP tell me about actual airflow once the fan is ducted on a roof?

That figure represents free-air delivery with no static pressure; real-world airflow will be lower once ductwork and roof resistance are added.
