Eminent Technology ET-2 Air Filter


I’m the original owner of an ET-2, which has served me faithfully since the 90s.  I have the original ET branded pump, but the air filter cartridge has turned black with dust.  My filter is clear plastic with a white paper cartridge, and it’s about the size of my thumb.  Any suggestions on getting a replacement?

Motor Guard D-12-2 is what I use.  They're much more substantial than the factory filter as they remove moisture, too.  The thread is 1/4" npt, so you'll just need to get some barbs from a hardware store to adapt it to your tubing.
