20-inch three-blade aluminum propeller with 22.5-degree pitch, 1/2-inch bore and reversible rotation for 1/3 hp direct-drive blowers at 1750/1740 RPM
- 20-inch diameter moves more air per revolution
- 5-degree pitch balances airflow and motor load
- Three aluminium blades resist corrosion and reduce weight
- 1/2-inch bore fits standard 12.7 mm shafts
- Reversible CW/CCW rotation suits intake or exhaust setups
20-inch 3-blade propeller for direct-drive blowers
This aluminium propeller measures 20 inches in diameter with a 22.5-degree pitch and a 1/2-inch bore. It is built for direct-drive blower units running at 1/3 horsepower and suits maintenance or replacement tasks in HVAC air-handling equipment.
Sustained airflow at fixed speed
The blade geometry delivers steady airflow at 1750 RPM or 1740 RPM depending on motor frequency. Aluminium construction resists corrosion during continuous operation, and the intake-side hub location keeps the flow path consistent under constant load.
Replaces worn or damaged propellers on matching
The part fits shafts with a 12.7-millimetre bore and serves as a direct swap for identical 20-inch three-blade units. The upgrade is worthwhile when vibration, blade fatigue or pitch deviation reduce the original blower's output.

Questions about this item
How much power does the 1/3 hp motor draw at 1750 RPM?
The propeller is rated for 1/3 hp at 1750 RPM, so the motor must supply that shaft power continuously.
What shaft size and motor speed are required to mount this 20 in propeller?
It fits a 1/2 in bore (12.7 mm) and is rated for 1750/1740 RPM direct-drive motors.
Can the CW/CCW hub work with an older single-rotation motor?
Yes, the reversible hub design allows installation on motors wired for either clockwise or counter-clockwise rotation.
