Kaeser Replacement 636230 OEM Compressor Air Oil Separator
 
Air / Oil Separators Used in Rotary Compressors Causes of failures/ apparent failures
 

• Multi scavenge line

 
Some compressor models have two scavenge lines both with in line small sintered bronze filters. When one filter becomes blocked it is often removed which then creates an imbalance of pressure between the scavenge lines resulting in oil carry over. Note: if the filters are replaced by orifice plates then both orifices must be of the same diameter.
Result: high oil carry over and saturation of separator if scavenge line pressures not equal.
 

• Scavenge line incorrectly connected

 
After improper compressor repairs it has been known that the discharge end of the scavenge line was connected to the pressure side of the air-end instead of the suction side. Compounding the error was the fitting of a non-return valve in the scavenge line.
Result: high oil carry over.
 

•  Shellac, dust, dirt or other particles in oil circuit

Typically a compressor air filter has a 25 micron rating, an oil filter 10 micron and an air / oil separator a 3 micron rating. Especially in dirty environments due to the fineness of the separator filter media it becomes a receptacle for particles not captured by the air or oil filter. The separator becomes clogged.
Result: rapid increase in differential pressure can result in separator implosion.
 

• Storage and handling of new oil

The oil should be stored away from sources of industrial contamination. The dispensing equipment (funnel and containers) must be clean. Partially emptied containers must not become fouled. Contamination of new oil will block the separator.
Result: high differential pressure.
