Aluminum three-blade propeller, 20 inch diameter, 5/8 inch bore, 22.3 degree pitch, clockwise rotation

Dayton

Dayton 10D968PG 20" 5/8" Bore 22.3° CW Blower

SKU CH-4S78-GMHM5

20-inch aluminum propeller with 5/8-inch bore and 22.3-degree clockwise pitch for direct-drive blower replacement

  • 20 inch diameter moves more air per revolution
  • 5/8 inch bore fits standard 15.87 mm motor shafts
  • 3 degree pitch optimises airflow at 1724 RPM
  • Three aluminium blades reduce weight while resisting corrosion
  • Direct drive design eliminates belt maintenance for 3/4 hp motors

Replacement Propeller for Dayton Blowers

This 20-inch aluminum propeller replaces the original component on compatible Dayton blower assemblies. It features a 5/8-inch bore and three blades set at a 22.3-degree pitch. The hub is centralized for direct-drive mounting. It is rated for 3/4 hp operation at 1724 RPM.

Verify Shaft Diameter and Rotation Before Ordering

Confirm that your motor shaft measures exactly 5/8 inch or 15.87 mm to match the bore. The propeller rotates clockwise when viewed from the drive end. Check that your existing housing accommodates a 20-inch diameter and a three-blade aluminum design. Ensure the hub location aligns with your motor mounting.

Direct-Drive Fit for 10D968D Blower Assemblies

This propeller mounts directly onto the motor shaft without belts or pulleys. It frees up space by eliminating drive-train components between the motor and the airflow path. The aluminum blades reduce rotating mass compared to steel alternatives. It is designed specifically for use with the 10D968D blower housing.

Questions about this item

Does the 20 in 22.3° CW aluminum propeller ship with mounting hardware or must I buy a 5/8 in bore hub separately?

The propeller is sold as a standalone replacement blade; mounting hardware and a matching 5/8 in bore hub are not included and must be sourced separately.

How do I decide between the 22.3° pitch version and any other pitch options for my 1724 RPM direct-drive motor?

Match the 22.3° pitch to the original equipment specification; using a different pitch will change airflow and motor load, so select the pitch called out for your specific blower assembly.

What does the 1724 RPM rating mean for actual airflow once this 20 in 3-blade propeller is installed on a 3/4 hp motor?

At 1724 RPM the propeller delivers the design CFM and static pressure engineered for the original 10D968D blower housing; actual airflow will match that spec when motor hp, voltage and ducting are unchanged.
