Replacement wheel for HS3 models

The Tjernlund 950-1013 wheel is a closed-base component designed to fit the HS3 fan assembly. It serves as a direct replacement part for existing installations. The accessory weighs 1.95 and carries the HAWA material designation. Buyers who need a different mounting style or a wheel for another fan series cannot use this item.

Simple drop-in installation

Installation consists of removing the old wheel and seating this unit onto the existing shaft of the HS3 housing. The closed-base design aligns with the original mounting points without additional hardware. Misalignment during fitting can cause vibration or reduced airflow, so the wheel must be centred before tightening. No wiring or configuration steps are required.

Steady airflow under continuous duty

Once fitted, the wheel maintains consistent air movement during prolonged operation of the HS3 unit. The HAWA construction resists deformation when the fan runs for extended periods. Performance remains stable without the drop-off sometimes seen in lighter impellers. The part is not intended for variable-speed drives or high-temperature exhaust streams beyond the HS3 rating.

Questions about this item

How can I verify the wheel spins freely after installing it on my HS3 unit?

Mount the wheel on the motor shaft, secure the set screw, then power the HS3; the wheel should rotate smoothly without wobble or unusual noise.

Does the package include mounting hardware or just the wheel itself?

The box contains only the closed-base HAWA wheel; mounting screws or adapters for the HS3 motor shaft are not included.

How do I confirm the 950-1013 wheel matches my Grainger 4KA75 fan?

Check that your fan carries Grainger item 4KA75 and Tjernlund model HS3; the 950-1013 wheel is specified for that exact combination.
