Hitachi 300-159 Spare Part - Fan

Original Hitachi replacement cooling fan — part no. 300159 — a direct-fit impeller designed to restore the motor cooling on Hitachi/Hikoki orbital sanders.

This compact plastic fan mounts on the motor/ventilation assembly to force air across the motor and bearings, reducing overheating and helping the tool run cooler and longer. It’s listed as the correct replacement for Hitachi models SV12SD and SV12V (also referenced as HKK300159).

The part is supplied as the single fan component ready to swap into the existing housing with the original mounting points and orientation — a straightforward repair step that gets your sander back to normal ventilation without replacing larger assemblies.

If you need a reliable part now, this genuine Hitachi fan is the specific item you want when searching for parts for power tools to fix cooling problems on the SV12 series.
