Dayton

Dayton VE10E031PG 20" 22.5° Propeller Blower

SKU CH-5R1G-ERMT4

A 20-inch aluminium propeller with 22.5-degree pitch, 1/2-inch bore and three blades for direct-drive blowers up to 1/3 hp at 1,694 rpm

  • 20-inch diameter moves more air per revolution
  • 5-degree pitch balances airflow and static pressure
  • Three aluminium blades resist corrosion while keeping weight low
  • Half-inch bore fits standard 1/3 hp motor shafts
  • Reversible CW/CCW rotation suits intake or exhaust mounting

20" Direct-Drive Propeller Blower

The Dayton VE10E031PG is a 20-inch diameter aluminum propeller designed for direct-drive HVAC blower applications. It operates at 1/3 horsepower with a fixed 22.5-degree blade pitch and reversible CW/CCW rotation. The three-blade hub mounts on the intake side with a 1/2-inch bore.

Replaces worn direct-drive propeller

This unit replaces an existing 20-inch direct-drive propeller when the original blades are damaged, corroded or out of balance. The jump is worth it when the motor still delivers 1/3 hp at 1694/1695 rpm and the mounting hub matches the 1/2-inch bore. It does not suit belt-drive housings or motors rated for different speeds.

Moves air in standard residential

The aluminum three-blade design handles typical supply and return airflow in ductwork sized for a 20-inch propeller at the rated rpm. Headroom runs out when static pressure exceeds what a 1/3 hp direct-drive motor can overcome or when the application demands a different pitch angle or blade count.

Highlights

  • 20-inch diameter moves more air per revolution
  • 5-degree pitch balances airflow and static pressure
  • Three aluminium blades resist corrosion while keeping weight low
  • Half-inch bore fits standard 1/3 hp motor shafts
  • Reversible CW/CCW rotation suits intake or exhaust mounting

Questions about this item

What motor shaft size does the 1/2 in bore of this Dayton propeller accept?

The 1/2 in bore (12.7 mm) fits a motor shaft of that exact diameter for direct-drive mounting.

How do I set the rotation direction when installing this 22.5° pitch propeller?

The hub is located on the intake side; orient the blades so they push air toward the hub for the desired CW or CCW rotation.

When should I replace the three aluminium blades on this 20 in propeller?

Replace the propeller if any blade shows cracks, corrosion or deformation that could unbalance the 1694/1695 rpm assembly.
