The ATLAS COPCO 2901-0566-00 separator replacement is a cost-effective alternative to the expensive OEM separator. It measures 6.61″ OD x 7.01″ tall with a 11.81″ OD flange and a 4.21″ ID. This aftermarket air/oil separator is made in the USA and offers oil separation equal to or better than the original OEM separator specifications.
A worn separator lets oil carry over into the air system and drives up both oil consumption and energy cost. This replacement separator restores proper oil separation, returning captured oil to the compressor while keeping pressure drop low.
- 2 – 3 PPM residual oil content in functioning systems
- Every air/oil separator is individually tested for electrical ground
- Borosilicate Microglass filter media is standard
- Top-quality gasket material
- Made in the USA
