36-inch replacement blade for 1/2 hp motors

This Dayton 23NU11 propeller measures 36 in across and mounts on a 5/8 in bore. It carries three aluminum blades rated for 850 rpm direct-drive operation. The part is built to fit the 2RDZ3 motor assembly.

Steady 850 rpm airflow without belt losses

Direct drive locks the blade to the motor shaft so speed stays constant at 850 rpm under load. Aluminum construction keeps rotational mass low for quick response when the motor ramps. The closed-base design maintains blade pitch through continuous duty cycles.

Aluminum blades resist corrosion in humid settings

The 5/8 in bore slides onto the matching shaft and secures with standard hardware. Three blades balance airflow and static pressure for the intended 1/2 hp rating. Propeller diameter and blade count are fixed, so the unit drops in without alignment adjustments.

Questions about this item

How much noise and heat does the 1/2 hp 850 rpm motor produce during continuous operation?

The 1/2 hp motor runs at 850 RPM with three aluminum blades; typical industrial direct-drive fans at this speed generate moderate airflow noise and minimal motor heat under normal load.

What existing fan assembly is required to mount the 36 in blade with a 5/8 in bore?

This replacement blade fits a 5/8 inch (15.87 mm) bore shaft and is designed for use with the Dayton 2RDZ3 motor assembly; verify your motor matches that specification before installing.

Will the 36 in three-blade propeller work with an older Dayton motor rated below 1/2 hp?

The blade is engineered for a 1/2 hp, 850 RPM direct-drive motor; using it on a lower-horsepower unit may reduce airflow and could overload the motor, so match the original 2RDZ3 specs for proper performance.
