Atlas Copco Oil-Injected Rotary Screw Compressor GA75+ 8 bar

Open the condensate sample valve at the side of the compressor for 5 seconds and dispose of the collected condensate according to local regulations for oil containing water

Re-open the test valve and collect the condensate in the test bottle

Compare the turbidity of the sample with the 15 ppm turbidity reference bottle

Is the turbidity of the test sample more intense than the reference turbidity?

If the turbidity of the test sample is more intense than the reference turbidity, a request for servicing should be initiated, to be carried out within 2 weeks time.

The vertical position of the test outlet ensures that there is enough clean activated carbon left above this position to keep the condensate under 15 ppm for at least 2 weeks.

Check coolers. Clean if necessary

Remove the air filter element and inspect. If necessary, clean using an air jet. Replace damaged or heavily contaminated elements

Check the filter element of the electric cabinet. Replace if necessary

Check air filter service indicator

Check that condensate is discharged during operation

On water-cooled units: check for cooling water flow

Condensate discharged when pressing the test button on top of the electronic water drain?

Stop the compressor, close the air outlet valve and switch off the voltage

Any dirt removed from the condenser inlet with a vacuum cleaner?

Cleaned with an air jet in the reverse direction of the normal flow?

Use low pressure air. Keep the compressed air nozzle more than 30 cm away from the condenser to avoid damaging the of condenser fins

Dust removed from inside the dryer with a vacuum cleaner?

Do not use water or solvents to clean the condenser

Is Atlas Copco Roto-Xtend Duty Fluid used?

The oil separator element must also be replaced when the pressure drop over it exceeds 1 bar (14.5 psi).

Enter the pressure drop while the compressor is running loaded and preferably with a stable working pressure.

Pressure difference monitoring is available?

Any visible damage or corrosion on the oil separator vessel?

Enter the minimum wall thickness of the oil separator vessel.
