This filter will fit any compressor that has 3/8" female NPT threads for the air filter to screw into as long as there is no room or clearance issues this filter measures 3" tall with threads and 2.5" in diameter. This filter was designed to eliminate compressor starting problems by allowing the compressor to reach full RPM before allowing air in.
