Simple Installation
The STEMCO Moisture Ejector is most commonly
installed at the wet or primary reservoir drain port.
Remove manual drain valve and install STEMCO
Moisture Ejector with special 1/4" N.T.P. nipple which
is included with the valve. Recommended actuator line
is 1/4" O.D. tubing which connects from the actuating
port of the STEMCO Moisture Ejector to the unloader
port of the governor.
Note: For more information on shop compressor or
stationary applications, ask for Tech Tip #3.
TYPICAL AUTOMOTIVE AND STATIONARY MOUNTINGS
How the Product Operates
1. The STEMCO Moisture Ejector is connected at the
air tank drain with a special 1/4" N.P.T. nipple which is
included with ejector.
2. The actuating end connects to the governor unloader
port or brake actuating line.
3. The STEMCO Moisture Ejector operates automatically
each time the air compressor “cuts in” and “cuts out”
when connected to the governor unloader port.
A. Air tank pressure furnishes ejection power.
B. Up to three ounces (or 5.42 cubic inches) of liquid
material can be ejected each time the ejector operates.
C. The powerful valve action also ejects foreign
matter, carbon compounds, and alkali scales which
form in air systems.
