Replacement Propeller for Dayton Ceiling Fans

This 30-inch diameter propeller fits Dayton models 1RWB4A and 1RWB5A. It features a 43/64 inch bore, equivalent to 17 mm, and three black powder-coated aluminium blades. The unit is rated for 1/4 hp direct-drive operation at 1100 or 900 RPM and is classified as a high-temperature type.

Sustained Operation at Dual Speeds

Running continuously at 1100 RPM or the lower 900 RPM setting, the aluminium blades maintain their shape and finish under high-temperature conditions. The powder coating resists corrosion during extended use, while the direct-drive connection avoids belt slippage or wear. The 1/4 hp rating supports steady airflow without overloading the motor.

Upgrading Worn or Damaged Original Propellers

This propeller replaces a cracked, warped or corroded original on the compatible Dayton units. The jump is worth it when vibration, noise or reduced airflow indicate blade fatigue. It is not for buyers needing a different blade count, bore size or diameter, nor for adapting to non-Dayton motor housings.

Highlights

  • 30-inch diameter moves more air per rotation
  • 11/16-inch bore fits 1RWB4A and 1RWB5A motors
  • Three black powder-coated aluminium blades resist corrosion
  • Dual-speed 1100/900 RPM direct drive matches load needs
  • High-temperature rated for demanding environments

Questions about this item

How much noise or heat does the 1100 RPM direct-drive propeller generate when running all day?

The 30-inch aluminium propeller runs at 1100 RPM or 900 RPM on a direct-drive 1/4 hp motor, so noise and heat will match that motor's rating; no separate acoustic or thermal figures are published for the blade itself.

What motor shaft size do I need to fit the 43/64-inch bore?

The propeller has a 43/64-inch (17 mm) bore, so the motor shaft must be exactly 11/16 inch in diameter to mount without an adapter.

Will this 30-inch replacement propeller work with my existing Dayton 1RWB4A or 1RWB5A fan assembly?

Yes, the supplier lists the propeller as compatible with Dayton models 1RWB4A and 1RWB5A, using the same direct-drive mounting and 30-inch diameter.
