How to Clean and Inspect an Air Compressor Air Filter

The intake filter protects the compressor from dust that scores rotors and blocks coolers. A clogged filter raises energy use and shortens component life. Here is how to inspect and clean it.

Inspection

  • Remove the filter and hold it to a light to check blockage.
  • Look for holes, tears or collapsed pleats.
  • Replace if damaged or saturated with dust.

Cleaning

  • Blow clean compressed air from the inside out.
  • Never wash a paper filter with liquid.
  • Wipe the housing and seal before refitting.

Replacement Interval

  • Replace per the service schedule, or sooner in dusty environments.
  • Use the correct grade and size of filter element.

How do I know the filter is clogged?

A visible dust layer, rising inlet vacuum or a service alarm indicates the filter needs attention.
