Three-blade aluminum propeller, 14 inch diameter, 19 degree pitch

Dayton

Dayton 14" Propeller 19° Pitch 1/20 HP 1720 RPM

SKU CH-JCTW-FMKD6

14-inch aluminum propeller with 19-degree pitch, 1/20 HP rating, and 1720 RPM direct-drive speed

  • 14-inch diameter moves high air volume
  • 19-degree pitch optimises airflow efficiency
  • Three aluminium blades resist corrosion
  • Direct drive at 1720 RPM reduces maintenance
  • 1/20 HP motor suits light-duty ventilation

14″ Propeller for Direct-Drive Blowers

This 14-inch aluminium propeller is built for direct-drive blower assemblies that require a 19-degree blade pitch. It suits maintenance technicians and system integrators replacing or specifying airflow components in HVAC equipment.

Thermals Noise and Power Draw

The three-blade aluminium construction keeps rotating mass low for 1720 RPM operation on a 1/20 HP motor. Direct-drive coupling eliminates belt losses and reduces mechanical noise compared with belt-driven alternatives.

Fit and Integration

A 5/16-inch bore (7.93 mm) mounts directly on the motor shaft with clockwise rotation and intake-side hub orientation. The assembly frees up space by removing belts and pulleys while matching the original 19-degree pitch specification.

  • 19-degree pitch optimises airflow efficiency
  • Three aluminium blades resist corrosion

Questions about this item

How do I install the 14 inch propeller with a 5/16 inch bore on a 1/20 HP motor?

Slide the propeller onto the motor shaft matching the 5/16 inch bore, secure it with the appropriate set screw or key, and verify the rotation is clockwise when viewed from the intake side.

What maintenance does the aluminum 3-blade propeller need over time?

Inspect the aluminum blades periodically for cracks, corrosion, or imbalance; clean debris buildup to maintain airflow, and replace the propeller if any blade damage or excessive vibration is detected.

At what point does the 1720 RPM direct-drive limit become a constraint during continuous operation?

The 1720 RPM direct-drive speed is fixed by the 1/20 HP motor; sustained operation cannot exceed this speed, and the limit appears first as motor thermal protection or airflow shortfall if system resistance rises.
