Symptom Possible Cause Corrective Action
Compressed air
has relatively high
oil content and oil
refilling period is
shortened.
1. Oil level in the air-oil receiver is too
high.
2. Filter or orifice in the oil return pipe
or the pipe itself is blocked.
3. Air-oil separator element, O-ring(s) or
gasket(s) is damaged.
4. Leakage in oil piping.
5. Oil is wrong grade or type causing
excessive foaming.
1. Check oil level and drain out any
excess.
2. Clean or replace filter element, orifice
and pipe.
3. Check or replace air-oil separator
element, O-ring(s) or gasket(s) and
check tightness of connections and
fasteners.
4. Check and rectify leakage.
5. Replace oil with correct grade and
type.
Oil mist leaks out
of air filter during
shutdown.
1. Nil or insufficient operation in
unloading mode before shutting down.
2. Solenoid valve, inlet valve or vent
valve is faulty.
3. Venting of air-oil receiver is
incomplete.
4. Minimum pressure valve is faulty.
1. Check and follow correct procedure
for normal shut down. Check the
controller’s time settings
2. Check or replace solenoid valve, inlet
valve or vent valve.
3. Check vent valve.
4. Repair or replace minimum pressure
valve.
Switching
between
unloading and
loading modes is
too frequent.
1. Air piping leakage.
2. The differential between the unload
and load pressure settings is too small.
3. Air consumption and system air
pressure fluctuate excessively.
4. The external compressed air receiver
is too small.
1. Check and rectify air leakage.
2. Check the controller’s pressure
settings.
3. Increase air storage capacity in the
user’s piping network.
4. Install an additional or larger
compressed air receiver.
