Product details
This genuine OEM Rexair-Rainbow upper fan spacer (Part #R1984) sets the clearance above the fan on the D-3C motor. It positions the fan on the shaft so air is drawn through the motor along the intended path.
An upper spacer that has worn or cracked lets the fan shift out of position, and the resulting misalignment can bring on vibration, noise, or a drop in suction. Poor spacing also accelerates wear on the fan and bearings. Installing the correct spacer restores the proper gap and steady airflow.
- Fits: Rexair-Rainbow D-3C motor
- Function: Sets the upper clearance for the motor fan
- Benefit: Keeps the fan aligned for efficient, quiet airflow
- Tip: Pair with the lower spacer if both are worn
The spacer slides onto the shaft above the fan during motor service. Verify your model reads D-3C before ordering, and restore the correct fan spacing for full suction.
