Roof Exhaust Fan 13 Inch Wheel
The Dayton 5DVT1 is a centrifugal downblast roof exhaust fan built for clean-air ventilation in commercial or light-industrial settings. It arrives fully assembled with a direct-drive motor and a 13 3/4 inch wheel diameter. The unit mounts on a 22 inch square base and operates on 115V single-phase power. It delivers 1,618 cfm at zero static pressure.
Direct Drive Replaces Belt Systems
This model uses a 1/6 hp direct-drive motor rated at 1,140 RPM, removing the belts, pulleys and tension adjustments found on older belt-driven roof fans. The jump is worth it when maintenance access is limited or when a simpler, quieter drivetrain reduces service calls. It is not suited for installations that require higher static pressure or larger airflow volumes than the listed maximums.
Low Pressure Clean Air Limits
The fan is rated for a maximum static pressure of 5/8 in wc and is approved only for clean-air streams. It will not handle grease-laden kitchen exhaust, hazardous fumes or high-resistance ductwork. Performance drops sharply as duct static pressure approaches the rated limit, so longer or more complex duct runs may exceed its capability.

Questions about this item
What roof opening is required for the 22 in square base?
The fan's base measures 22 in by 22 in square, so the roof curb or opening must accommodate those outer dimensions.
How is the direct-drive motor wired at 115V AC single phase?
Connect the factory-wired motor leads to a 115V AC single-phase supply; no belt alignment is needed because the wheel mounts directly on the motor shaft.
When should the 13 3/4 in wheel be inspected or replaced?
Inspect the wheel annually for debris buildup or corrosion; replace it if blades are cracked, bent, or if airflow drops below the rated 618 cfm at .000 in SP.
