Oil-Gas Separator
Advantage
1.Filtering precision:0. 1 Micron.
2.Oil contained in compressed is below 3ppM.
3.Filtration efficiency:99.999%.
4.Service life is approximately 3000h-6000h.
5.Initial pressure differential less than 0.02Mpa.
6.Filter element of air oil separator is made by the thin fiberglass, which imported from HV&Lyd.
Lubricated rotary screw air compressors mix oil with the intake air to lubricate the compressor’s screws. After the air is compressed an air/oil separator separates compressed air from compressor oil. The compressor lubricant collects at the bottom of the separator tank and the compressed air continues to the air receiver. A standard rotary screw separator reduces the lubricant entrained in the compressed air to 2-3 ppm. Under normal operating conditions an oil separator’s service life is 4,000 to 6,000 operating hours.
ANKA Filter chooses the excellent quality materials for all end covers, filter materials, and glue, the highest configuration. The filter material adopts imported American glass fiber, which has a long service life, guarantees the filtering effect, and reduces fuel consumption.

How to select the right oil-gas separator
The separator element is what decides how much oil leaves the machine with the air. Ours is rated 0.1 micron, with residual oil below 3 ppm and a filtration efficiency of 99.999 %.
- Pressure drop — initial differential below 0.02 MPa. That is the number to watch: a separator that has reached 0.1 MPa is costing you energy whether or not it is passing oil.
- Service life — about 3000–6000 hours, depending on the oil, the oil temperature and how clean the intake air is.
- Media — thin fibreglass from HV and Lyd, the same suppliers used by the major OEMs.
- Selection — choose by machine model and separator part number, not by size alone; the end caps and the gasket profile differ between models even when the diameter looks the same.
Installation and maintenance
- Fit the element with clean hands and no oil on the gasket seat; a folded or twisted gasket lets oil bypass the element entirely.
- Do not over-tighten the retaining nut — the element is held by the gasket, and over-compression splits the end cap.
- After fitting, run the machine and check the differential; a high reading on a new element usually means the gasket is not seated.
- Change the oil filter at the same time. A separator fitted onto dirty oil fails early, and the two parts are always serviced together.
Oil-gas separator FAQ
How do I know the separator needs changing?
Two signs: oil consumption rises (oil appears in the line or at the dryer), or the pressure differential climbs. Change at whichever comes first, and at the hour interval in the manual if neither appears.
Can I clean and refit a separator element?
No. The fibreglass media is destroyed by washing and the element will pass oil afterwards. It is a replaceable part.
Why did a new separator start passing oil after a week?
Usually a damaged gasket, an element fitted the wrong way round, or the minimum pressure valve holding less than 4.5 bar — the separator needs that pressure to work. Check the valve before blaming the element.
