Don’t be alarmed if you find oil in your air compressor tank. Actually, all rotary screw compressors pass trace amounts of oil in the
compressed air. The question is how much is the normal amount of oil in my compressor tank?
Normal oil carry-over
Coalescing filters play a big role in keeping the oil out of your tank. Depending on the upkeep, maintenance and overall condition of the
compressor will depend on how much oil is being passed along downstream. A trace amount of oil may appear in your tank, which is a normal
amount typically seen and nothing to be alarmed about.
Excessive oil in your tank
If you have oil actually “pooling” in your tank, you may have a few things going on with your compressor. Your separator may be saturated,
punctured or even collapsed which is creating excessive oil carry over. Additionally, if the scavenger lines or check valves are plugged and
not working, that will create excessive oil carryover.
Routine Checks to Help:
- Record the differential across your separator.
- Stay up on routine separator maintenance.
- Use Original OEM separator which is designed to remove the most oil carry over.
- Regularly drain your air receiver tank.

efforts on the following:
Air is always contaminated with solid particles such as dust, sand, soot, salt crystals and water as it leaves the compressor. An effective
compressed air treatment system lowers the dew point of the air and takes out the elements that may harm equipment downstream of the
compressor and dryer
The ambient temperature in an air compressor’s environment can greatly affect your air compressor’s performance. All air compressors will
generate some amount of water, but depending on inlet air conditions some can produce large amounts of water.
