AIR/OIL COALESCER
The air/oil coalescer employs an element permanently housed within a spin-on canister. This is a
single piece unit that requires replacement when it fails to remove the oil from the discharge air, or
pressure drop across it exceeds 15 PSI. Dirty oil clogs the element and increases the pressure
drop across it.
To replace element proceed as follows:
1. Shutdown compressor and wait for complete blow down (zero pressure).
2. Turn element counterclockwise for removal (viewing element from bottom).
3. Apply a film of fluid directly to seal on the new element.
4. Rotate element clockwise by hand until element contacts seal (viewing element from
bottom).
5. Rotate element approximately one more turn clockwise with band wrench near the top
of element.
6. Run system and check for leaks.
DO NOT SUBSTITUTE ELEMENT. USE ONLY A GENUINE BOSS INDUSTRIES
REPLACEMENT ELEMENT. THIS ELEMENT IS RATED AT 200 PSI WORKING
PRESSURE. USE OF ANY OTHER ELEMENT MAY BE HAZARDOUS AND COULD
IMPAIR THE PERFORMANCE AND RELIABILITY OF THE COMPRESSOR,
POSSIBLY VOIDING THE WARRANTY AND/OR RESULTING IN DAMAGE TO
PROPERTY AND SERIOUS BODILY HARM.
COALESCER OIL RETURN
This originates at the bottom of the air/oil coalescer and flows through a special recovery pipe and
venturi nozzle. If the coalescer starts to fill with oil there is a good chance the venturi or pipe has
been plugged. Consult factory for cleaning instructions.
