Aluminium 5-blade propeller 12 inch diameter 1/2 inch bore

Dayton

Dayton 10D963PG 12" 1/2" Bore 34.1° Propeller Blower

SKU CH-27K4-WHN50

A 12-inch, five-blade aluminum propeller with a 1/2-inch bore and 34.1-degree pitch for direct-drive blower replacement

  • 12-inch diameter moves more air per revolution
  • 1-degree blade pitch optimises airflow efficiency
  • 1/2-inch bore fits standard motor shafts directly
  • Five aluminium blades balance strength with light weight
  • 1,772 RPM rating matches 1/4 HP motor output

12-inch direct-drive propeller

The Dayton 10D963PG is a 12-inch aluminum propeller designed for direct-drive blower assemblies. It mounts on a 1/2-inch bore shaft and operates at 1772 RPM with a 34.1-degree blade pitch. The five-blade, clockwise-rotation design suits HVAC technicians and maintenance teams replacing worn impellers on compatible equipment.

Replaces 10D963D propeller

This propeller serves as a direct replacement for the 10D963D model in blower units rated for 1/4 hp motors. The upgrade is worth it when the original impeller shows blade fatigue, corrosion or imbalance that reduces airflow. Matching the original diameter, bore, pitch and rotation ensures the motor load and airflow curve remain unchanged.

Handles 1/4 hp at 1772 RPM

The aluminum construction and centralized hub deliver stable operation at the rated speed and power. It comfortably moves air in residential and light-commercial HVAC blowers within those limits. The propeller runs out of headroom if the motor exceeds 1/4 hp or if system static pressure demands a steeper pitch or higher RPM than the 34.1-degree, 1772 RPM design provides.

Questions about this item

Will the 12 in diameter and 1/2 in bore fit my 10D963D motor shaft?

Yes. The propeller is built for the 10D963D model with a 12 in diameter, a 1/2 in (12.7 mm) bore and a centralized hub that matches that motor shaft.

How do I install the 5-blade aluminum propeller on the motor shaft?

Slide the 1/2 in bore onto the motor shaft, align the keyway if present, then tighten the set screw firmly; the step often missed is verifying clockwise rotation before securing the hub.

When should I replace the aluminum blades on this 34.1° pitch propeller?

Replace the propeller if any of the five aluminum blades show cracks, bending, corrosion or imbalance that causes vibration at 1772 RPM.
