There are a number of reasons why compressor oil may be carrying over into the air stream, with the most common being:
- Compressor oil too full.
- VMAC compressor oil is clear when new which can sometimes make it difficult to read the oil level in the sight glass. Ensure the compressor has not been over filled.
- Incorrect compressor oil.
- Use only VMAC high performance synthetic oil.
- Incorrect shutdown procedure.
- Follow the shutdown procedure documented in the owner's manual.
- Internal VMAC system pressure is being allowed to drop below 60 psi.
- Ensure the compressor is sized correctly for tool (is compressor cfm adequate to run the tool)
- Lack of service, coalescing filter compromised.
- Refer to the VMAC Owner's Manual for servicing intervals.
- Poor fit between the coalescing filter and the AOST.
- When servicing, ensure the coalescing filter is seated correctly.
- Clogged or kinked scavenge line.
- Clear the scavenge tube of any blockages or restrictions.
- Air Oil Separator Tank is not correctly aligned (VMAC UNDERHOODTM systems only).
- Ensure the arrow on the blowdown cap is pointing up.
- System is being used on too steep an angle (All systems that utilize an Air Oil Separator Tank).
- Ensure the system is level (15° or less).

Compressor Leaks Air. If you shut down the compressor when the tank is filled with air and then find that the pressure gauge is showing a drop in pressure, you know that the compressor is leaking air. If you plug in the compressor, the pressure switch response to the air leak and dropping compressor pressure will be to start the compressor again. 2021 Atlas Owner's Manual: Touring Coach: View Download ⤓ 2021: 2021 Bambi Owner's Manual: Travel Trailer: View Download ⤓ 2021: 2021 Bambi Parts Book: Travel Trailer: View Download ⤓ 2021: 2021 Basecamp Owner's Manual: Travel Trailer: View Download ⤓ 2021: 2021 Caravel Owner's Manual: Travel Trailer: View Download ⤓ 2021: 2021.
