Maintenance
Problem Cause Solution (go sequentially)
Inlet air pre-filter mat clogged
Clean/change pre-filter mat by following these steps:
Switch off the machine.
Squeeze and pull out the pre-filter mat from the
canopy.
Clean pre-filter with compressed air at less than 2.5
bar /36.3 psi 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 compressor
2. Arrest all pipeline leakages.
2. Working pressure is lower than required
application pressure.
3. Excess pressure drop in pipe line.
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 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
Pressure regulator (applicable only to EG 55
to EG 250) setting lower than working
pressure
1. Check and reset pressure regulator setting
to working pressure+0.3bar (4.35 psi).
2. Change pressure regulator assembly.
Actuator failure (applicable only to EG 55 to
EG 250)
Check/change actuator / kit / assembly.
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.
