The right part

Guessing at a fix vs. the correct fan

When an HD compressor motor loses its cooling, the fix is the fan built for that model. Improvising rarely holds up.

Running without it

Missing or wrong fan

  • A motor that loses airflow can overheat during continuous running
  • Guessing at a generic fan may not match your HD unit
  • Downtime while your aeration sits idle

Questions

HD Replacement Fan questions

Details to help you pick the correct cooling fan for your Koenders HD compressor.

What does the HD Replacement Fan do?
It keeps your Koenders HD compressor motor cool by moving air across it while it runs. That steady cooling is what lets the unit run continuously without overheating.
Which units does it fit?
It is available for the Koenders HD250 and HD450 compressors. Choose the model that matches your unit: HD250 Grey, HD450 Grey A, or HD450 Black B.
How do I choose the right model?
Select the option that matches your compressor. There is a fan for the HD250 (Grey) and two options for the HD450 (Grey A and Black B). Match the model to the unit you own.
Why would I need to replace the fan?
