tight on room in my cabinet, is this the kind that’s filter and regulator all in one piece?
Answer by: Customer Support on Oct 13, 2025, 8:32 AM
Space-wise, it helps because it is a piggyback unit that combines an air filter and an air regulator in one compact assembly. It uses 1/4 NPT ports, includes a pressure gauge, and has a manual drain on the filter bowl.
