Maintenance
Problem Cause Solution (go sequentially)
Inlet air pre-filter mat clogged
Clean/change the pre-filter mat by following these
steps:
Switch off the machine.
Squeeze and pull out the pre-filter mat from the
canopy.
Clean the pre-filter with compressed air at less than
7 bar g.
Refit the filter after cleaning.
Pressure not built
up
Clogged air filter element
Clean/change air filter element
1. Air requirement is more than compressor
capacity
1. Replace the compressor.
2. Arrest all pipeline leakages.
2. Working pressure is lower than required
application pressure
3. Excess pressure drop in pipeline
No control air supply to solenoid valve Replace / connect the control line tubes.
Solenoid valve malfunctioning
1. Replace the solenoid valve assembly.
2. Clean the orifice.
No electrical control supply to solenoid valve Replace the microcontroller.
Intake valve malfunctioning Check and replace the intake valve kit.
Blow-down valve malfunctioning
1. Check and change the BDV assembly.
2. Clean the orifice.
MPV malfunctioning
1. Check and change the MPV kit.
2. Check and change the MPV assembly.
Separator element choked (increase in
pressure drop across separator)
Replace the separator element. If required, replace
oil (based on the condition of oil) and run the
compressor.
2. Change pressure regulator assembly.
Actuator failure (applicable only to EG 55 to
EG 250)
Check and change actuator / kit / assy.
Separator element choked (increase in
pressure drop across separator)
Replace separator element. If required replace the
oil (based on condition of the oil) and run the
compressor.
