Blog: Compressed Air the Fourth Utility
A reader emailed me with an interesting situation that probably happens all the time. He has pneumatics inside a clean room but his “building” compressed air is neither dry nor clean. This poses a tricky situation as any sir that feeds this pneumatics must be clean enough to no contaminate the clean room. Also, these filters must no have automatic drains which could unexpectedly dump contaminant into the room. I recommended that he mount a dryer just outside the room. Our Parker Balston Membrane Air Dryers are a good choice as they don’t use any electricity and are easy to install and maintain. The dryer assures that there will be no further condensation inside the clean room that would need to be drained fro the filters. Inside the clean room the filters must have manual drains and be of fairly high efficiency, at least 99.99% at 0.01 micron or higher.
