Dayton

Dayton VE10D974PG Propeller Blower 18" 22° Pitch

SKU CH-PCZJ-HBSP2

An 18-inch aluminum propeller blower with a 22-degree pitch, 1/2-inch bore and three blades for direct-drive applications

  • 18-inch aluminium propeller moves air efficiently at 1700 RPM
  • 22-degree blade pitch optimises airflow for direct-drive HVAC applications
  • Three-blade aluminium construction keeps weight low while resisting corrosion
  • 1/2-inch bore fits standard 1/3 HP motor shafts without adapters
  • Clockwise rotation with intake-side hub matches common blower housing designs

Dayton 18-inch propeller blower

The Dayton VE10D974PG is an 18-inch diameter propeller blower designed for direct-drive HVAC installations. It suits technicians and facility managers who need a replacement impeller for air-handling equipment running at 1700 RPM. The three-blade aluminium construction with a 22-degree pitch delivers consistent airflow in compatible units. Buyers who need a different bore diameter or rotation direction should verify specifications before ordering.

Thermals noise and power draw

The blower operates at 1/3 horsepower with a direct-drive motor running at 1700 RPM, so power consumption matches that rating under normal load. Aluminium blades reduce rotating mass, which helps limit vibration and associated noise in ductwork. Hub location on the intake side supports smooth air entry for steady thermal performance across the coil. No additional cooling or lubrication requirements are specified for this component.

1/2-inch bore with clockwise rotation

The critical fitment detail is a 1/2-inch bore (12.7 mm) paired with clockwise rotation when viewed from the intake side. This combination determines whether the propeller mates correctly with the existing motor shaft and housing. An incorrect bore or opposite rotation will prevent installation or reverse the airflow direction entirely. Confirm both values against the equipment nameplate before purchase.

Questions about this item

How do I fit this 18-inch propeller onto a 1/2-inch motor shaft?

Slide the 12.7 mm bore over the shaft and secure it with a set screw or key; the hub sits on the intake side so the three aluminium blades pull air toward the motor.

What part of this blower wears out first and when should I replace it?

The aluminium blades can fatigue or bend after long runs at 1700 RPM; inspect them each season and swap the propeller if you see cracks or vibration.

At what point does this 1/3 hp direct-drive unit hit its thermal limit during continuous operation?

The motor driving the propeller is rated for 1/3 hp at 1700 RPM; sustained loads beyond that rating will cause overheating before the blades reach any aerodynamic stall.
