Direct-Drive Roof Exhaust Fan

The Dayton 6KWK6 is a centrifugal downblast roof exhaust fan built for clean-air applications. It ships fully assembled with the motor and drive package included, so installation begins as soon as the unit reaches the roof. The 115 V AC single-phase motor delivers 1/4 hp and moves 864 cfm at .000 in static pressure. This model suits facilities that need a ready-to-mount roof ventilator without separate component sourcing.

Static Pressure and Air-Type Limits

The fan is rated for a maximum static pressure of 1 in wc and is not intended for high-static-pressure systems. It is approved only for clean air streams, so environments with grease, chemicals or particulate loads fall outside its design envelope. The 22 in square base fits standard roof curbs, but the unit cannot overcome duct runs that exceed its pressure capability. Buyers who need higher pressure ratings or contaminated-air handling must select a different fan class.

11 in Wheel Diameter

The 11 in wheel diameter is the single dimension that determines airflow capacity and curb compatibility for this direct-drive unit. It fixes the 864 cfm rating at free air and sets the physical footprint on the 22 in square base. If the project calls for a larger or smaller wheel to match an existing curb or to hit a different flow target, this model will not meet the requirement.

Questions about this item

Should I choose the 11 in wheel diameter or a different size for my roof exhaust needs?

The 11 in wheel diameter is the only size offered for this Dayton 6KWK6 model; select it when your roof opening and airflow requirements match the 864 cfm at 0.000 in SP rating.

What does the 864 cfm airflow figure mean once the fan is installed on a roof?

It indicates the fan moves 864 cubic feet per minute of clean air at zero static pressure; actual airflow will drop as ductwork, filters or roof curbs add resistance up to the 1 in wc maximum static pressure.

How does the 115V AC single-phase power interface limit where I can install this fan?

The motor requires a standard 115V AC single-phase supply, so installation is limited to locations with that voltage available; no three-phase or higher-voltage wiring is needed.
