Water Separator with Adapter

Air-line moisture management

The Spray Gun Water Separator with Adapter is an in-line air treatment component that removes water, oil and particulate from compressed air before it reaches the gun. Contaminated air is a common cause of water spotting, fisheyes and inconsistent atomisation in spray application. The unit fits HVLP and conventional setups through the supplied adapter and is normally installed at the gun inlet, in addition to any separator fitted at the compressor. Drain the unit regularly, particularly in humid conditions.
