How to change the oil separator of screw air compressor

Where is the oil separator located on a rotary screw compressor?

Air-oil separators typically used on rotary screw compressors, are located just after the compressed air leaves the compressor, installed in the compressors discharge line. This is so the oil can be removed and recycled back into the lubrication process.

How does an air compressor oil separator work?

The oil separator separates the oil from the air as the oil is needed to stay inside the compressor to keep lubricating the system, while the compressed air needs to exit the compressor free of oil so it can reach the pneumatic devices at the end of the line without damaging them. How Does an Air Compressor Air-Oil Separator Work?

How do you separate oil from a compressor?

Oil separators. The best method is to intercept the oil, just when it has left the compressor, in an oil separator. Usually larger droplets are separated in a system of baffles, while the finer drop-lets are separated in a demister. Observe that a demister is not a sieve. This prevents par-ticles larger than the holes in the sieve from passing.

How to energise a compressor & oil separator?

Switch “ON” the main switch isolator “Q10” and the selctor “Q12”. In this way the electric heaters of the compressors and the oil separators are energised. Check if the software installed on the microprocessor is corresponding to the unit type and the set point are correct.

How do you change oil on a screw air compressor?

In basic terms, the oil change process for a screw air compressor looks something like this: Clean the area near the compressor’s tank and oil filter to avoid contamination. Remove the oil drain plug and empty the old oil into a sufficiently large container.

How much oil does an oil separator return to a compressor?

Some oil separators can return more than 99 % of the oil to the compressor, but normally it is in the order of 80 %. An oil separator should be used whenever there are prob-lems with oil retention in the evaporator. This will most likely be more severe the lower the temperature is.
