TWO STAGE AIR FILTER/REGULATOR MAINTENANCE:
If the air is clean and dry, the system should operate trouble-free for years.
The
air filters
consist of a
5 micron
and
0.01 micron oil coalescing
filter. All
have replaceable elements.
To replace the element in the
5 and 0.01 micron air filters
on the
two stage
filter/regulator:
STEP 1 - SYSTEM AIR SUPPLY HOSE
Disconnect the
system air supply hose (blue)
to the
air filter
, this will
depressurize the
air filters
and allow them to be safely serviced.
STEP 2 - ZINC BOWLS
Remove the zinc bowls of the
air filters
by sliding the black bu on
downward and twisting the bowl about 1/10 of a turn. The bowl should
slide downward from the upper portion of the filter revealing the filter
elements. The elements can be removed by unscrewing them (like a light
bulb). When replacing them be sure they are hand tight.
STEP 3 - FLOAT DRAINS
Wash out any deposits and oil build-up from the filter bowls with warm
water and soap. Ensure the float drains are operating freely by shaking
them. They should ra le. The float drains can be tested by filling the
bowls with water, assembling of bowl to the filter and reconnecting to
the air supply. The water should drain from the bowls.
