Manufactured from aircraft grade materials and anodised for corrosion protection, this unit is extremely light weight and rugged. The OS8850 has been designed to remove the oil from the crankcase breather on Lycoming and Continental Engines. This gives reduced oil consumption, cleaner aircraft, and environment.
The CS850 has some unique features that make it the best on the market.
Using the Andair Oil/Air Separator since 2015 on my C-A185F in conjunction with the CT850 trap. After several hours of flying the trap has about a teaspoon or less oil and depending on the flying environment a few drops of emulsified water/oil captured. No delectable oil on the belly from the case vent. Since the condensed oil and occasionally some emulsified water/oil is captured in the CT850 trap and NOT RETURNED to the engine it keeps that oil from contributing to engine corrosion. A very well machined and designed product and beautifully finished.
Just installed this on a Sportsman with a Lyc IO-390. Added 8 qts of oil with oil change and it's still at 8 qts after several hours of flying. Adding 8 qts before installing the air/oil sep would immediately blow out any oil above 6-1/2 qts.

The unit itself does not have an FAA approval. Cirrus may have included it for their OEM STC, but I could not find any info that Cirrus uses this as standard equipment.
