TROUBLESHOOTING
Prolonged operation
of the compressor
Compressor is noisy
(knocking, metal
noises)
Dryer does not dry
(condensed water in
the air) *
Degraded drying
performance – high-
pressure dew point
(condensed water in
the air)
Dryer emitting high
levels of noise
)* Clean inside surfaces of the air tank thoroughly and remove all condensed liquid after dryer
failure.
Once a dryer fault is cleared and after its reassembly, the dryer should quickly be regenerated,
best when using continuous compressor operation at a pressure of around 1 bar for a period of at
least 1 hour; then check the dryness of the compressed air.

Air leakage in pneumatic system
Worn piston ring
Dirty inlet filter
Incorrect function of solenoid valve
Damaged piston bearing, piston rods,
motor bearing
Loose (cracked) dampening element
(spring)
Defective cooler fan
Damaged dryer
Low operating pressure
Regeneration solenoid valve not
working
Air regeneration nozzle plugged
Cooling fan not working
Dirty cooler
Clogged silencer in the condensate
collection tank
Defective dryer electronics
The compressor operated in a
higher mode (S3> 80%)
Damaged fan
Damaged silencer
High pressure in equipment due to
excessively clogged filters
Check pneumatic system – seal loose
connection
Replace worn piston ring
Replace dirty filter with new filter
Repair or replace fan or coil
Replace damaged bearing
Replace damaged spring
Replace fan
Check power source
Replace dryer
Reduce the demand for air, check
the output from the compressed air
source,
distribution system
Check coil operation, replace if
damaged
Inspect the condition of the valve –
clean
problems persist
Clean or replace the nozzle
(see product maintenance)
Check the power source to the fan
Replace damaged fan
Inspect the cooler and clean as
necessary
Check the condition of the silencer.
In the case of high flow resistance,
replace the silencer
Check the display electronics, and if
the display shows the compressor
run time, check the connection of
the control electronics. In case of
malfunction, replace the electronics
Keep the compressor running in a
mode that is less than S3-50%. The
dryer will automatically regenerate.
Do not switch off the compressor!
Replace damaged fan
Replace the silencer
Change the cartridges in the dryer
