COMPRESSOR OIL FILTER (Figure 5-3, page 40) - This patented design screw on oil filter is a vital part
in maintaining a trouble-free compressor, since it removes dirt and abrasives from the circulated oil. The
oil filter relief valves are located in the top manifold of the filterstat. To replace, unbolt the manifolds and
remove valves. The relief valve opens in the event the element becomes dirty enough to block the flow of
oil.
DANGER
Air/oil under pressure will cause severe personal injury or death. Shut down
compressor, relieve system of all pressure, disconnect, lockout and tagout
power supply to the starter before removing valves, caps, plugs, fittings, bolts
and filters.
DANGER
Compressor, air/oil reservoir, separation chamber and all piping and tubing
may be at high temperature during and after operation.
CAUTION
Improper oil filter maintenance will cause damage to equipment. Replace filter
element every 1000 hours of operation. More frequent replacement could be
required depending on operating conditions. A filter element left in service too
long may damage equipment.
Use the following procedure to replace the filter. Do not disturb the piping:
