The Clean air™ filter should not be mounted on or
near the air compressor.
The temperature of air is greatly increased during compression. As the
air cools down to room temperature, in the air line, on its way to the
spray gun, the moisture contained in it condenses. Thus, for maximum
effectiveness, the oil and water extractor should be mounted at some
point in the air supply system where the temperature of the com-
pressed air in the line is likely to be lowest.
air lines must be properly drained.
Pitch all air lines away from the compressor so that condensed moisture
can be drained off. Each low point in an air line acts as a water trap. Such
points should be fitted with an easily accessible drain. See diagram above.

oil and Water extractor should be at least 25 ft. from the compressor. further if possible.
air pressure at the gun is important.
Atomizing pressure must be set to allow for the drop in air pressure
between the regulator and the spray gun.
a Devilbiss Clean air™ filter is important.
A Clean Air™ filter serves a double purpose. It
eliminates blistering and spotting by keeping air
free from oil and water... and its precision air
regulator makes possible perfect air pressure
control at the gun.
The best spray gun in the world will not operate
efficiently without a good compressor and a
Clean Air™ filter. Model HFRL-508 is recommended.
If you are attempting to get a fine finish without the use of a Clean Air™
filter you will not succeed.

25 feet of 5/16” I.D. hose has a drop of only 5 PSI.
For this reason we recommend the use of 5/16” hose.
