20 in belt-drive supply fan
This Dayton 3FKD4 is a 20 in blade-diameter supply fan built for standard-duty air movement. It arrives without a motor or drive package so the installer can match horsepower and speed to the application. The six steel blades and stamped steel frame suit commercial or industrial ventilation where a belt-driven arrangement is preferred. It is not for buyers who want a direct-drive unit with an integrated motor.
Airflow from 3,581 to 4,587 cfm at up to .75 in wg
At the minimum motor speed of 953 RPM the fan moves 3,581 cfm, while the maximum speed of 1,221 RPM delivers 4,587 cfm against a static pressure of .75 in wg. The belt-drive design lets the system maintain these outputs across the 1/4 to 1/2 hp motor range without the drop-off seen in fixed-speed direct-drive models. It is not for installations that need variable-speed control without adding a separate drive.
Fits a 22 1/2 in square cut-out
The frame requires a 22 1/2 in by 22 1/2 in opening and ships without a belt guard, so the installer must supply one to meet safety codes. The stamped construction keeps weight manageable for two-person mounting, but the absent drive package means pulleys, belts and motor alignment are additional steps. It is not for teams expecting a complete plug-and-play assembly.

Questions about this item
How much electricity does the 1/2 hp motor on the Dayton 3FKD4 draw when running all day?
The fan operates with motors between 1/4 hp and 1/2 hp at speeds from 953 to 1,221 RPM, moving up to 4,587 cfm at 0.75 in wg static pressure.
What mounting hardware and motor must I already have to install this 20 in blade unit?
The stamped steel frame needs a 22 1/2 in square cut-out; you supply a 1/4 to 1/2 hp motor, pulleys, belts and mounting fasteners.
Will the 6 steel blades on this supply fan vibrate excessively when paired with an older 1/4 hp motor running at 953 RPM?
At the minimum 953 RPM the fan still delivers 3,581 cfm, and the rigid steel blade construction keeps vibration low even at reduced speed.
