3-Inch 10-Blade Aluminum Replacement Propeller

The Dayton 5JLK2 is a 3-inch diameter propeller with ten aluminum blades set at a 30-degree pitch. It is designed as a direct replacement for compatible ceiling fan motors requiring a 1/4-inch bore. The unit delivers 60 cfm at zero static pressure and operates up to 3,000 RPM with clockwise rotation facing discharge.

Fits 1/4-Inch Bore Motors with Two Set Screws

Installation requires a motor shaft measuring 1/4 inch in diameter and rated for 1/250 horsepower. The propeller secures with two set screws and includes no keyway, freeing the builder from aligning a key. Blade width is 9/16 inch, and the assembly is restricted to clockwise discharge rotation only.

Aluminum Blades Reduce Weight for Responsive

The ten aluminum blades lower rotating mass compared to heavier materials, allowing quicker speed changes within the 3,000 RPM limit. No additional accessories or software are bundled; the package contains only the propeller itself. Buyers needing counter-clockwise rotation or a different bore size must source an alternative model.

Questions about this item

Will the 3 in diameter and 30 degree pitch propeller hit a thermal or RPM ceiling first under continuous operation?

The propeller has a maximum speed of 3,000 RPM and is designed for a 1/250 HP motor, so the motor’s power limit will be reached before the propeller’s RPM ceiling.

How much heat or noise does the aluminum 10-blade propeller add when running all day?

Aluminum construction keeps the propeller light, reducing motor strain and vibration, while the 30 degree pitch moves 60 CFM at zero static pressure with minimal turbulence.

What motor shaft and mounting hardware must I already have to install this propeller?

You need a motor with a 1/4 in bore shaft, clockwise rotation facing discharge, rated at 1/250 HP, plus two set screws to secure the propeller.
