Replacement Propeller for Industrial Fans

This 24-inch Dayton propeller replaces worn or damaged blades on compatible industrial fans. It fits a 3/4-inch bore shaft and uses two set screws with a 3/16 by 3/32 inch keyway for secure mounting. The four-blade design moves up to 5,300 CFM in free-air conditions.

Airflow Performance Across Static Pressure

At zero static pressure the propeller delivers 5,300 CFM, dropping to 4,910 CFM at 0.125 inches SP and 4,360 CFM at 0.250 inches SP. At 0.375 inches SP the output falls to 3,775 CFM while the maximum speed remains 1,725 RPM. The cast aluminium blades are spark-resistant for safer operation in hazardous environments.

Clockwise Rotation and Half-Horsepower Motor

The propeller rotates clockwise when viewed from the discharge side and requires a 1/2 HP motor running at up to 1,725 RPM. Installers must verify shaft diameter, keyway dimensions and rotation direction before ordering because mismatched parts will not fit or will move air in the wrong direction.

Questions about this item

How much noise and heat does this 24-inch, 3/4-inch bore propeller generate when running continuously at 1725 RPM?

The propeller itself has no motor, so it produces no heat. Air-moving noise at 5300 CFM will depend on the motor and housing you pair it with.

What motor shaft and mounting hardware must I already own to install this 3/4-inch bore, 3/16-inch keyway propeller?

You need a motor with a 3/4-inch shaft, a matching 3/16-inch keyway, and capacity for two set screws. The motor must supply 1/2 HP at up to 1725 RPM clockwise.

Will this clockwise, 16-degree pitch propeller work with my existing 1/2 HP motor rated for 1725 RPM?

Yes, if your motor turns clockwise facing discharge, has a 3/4-inch shaft with a 3/16-inch keyway, and delivers 1/2 HP at 1725 RPM.
