The STEMCO Moisture Ejector provides a proven, inexpensive way to help assure the constant removal of oil, carbon, dirt, sludge and water from the air system, eliminating the daily chore of purging wet tanks.

Engages with a one-second blast of air every time the air compressor governor cuts in and out.

Installs at the wet or primary reservoir drain port with N.T.P. nipple included with the valve.

Increase effectiveness and longevity with simple cleaning. Built to perform reliably for up to five years.
