Atlas Copco 1625481151 Air Oil Separator Element

The Atlas Copco 1625481151 is an OEM spin-on air/oil separator element designed for oil-injected rotary screw compressors. It separates lubricating oil from compressed air to ensure clean outlet air quality and oil recovery for recirculation. The filter media utilizes high-efficiency fiberglass coalescing layers to achieve low oil carry-over rates, typically below 3 ppm, minimizing oil consumption and protecting downstream pneumatic equipment. Engineered for precise OEM fit, this separator replaces previous part numbers 1625481100, 1625481101, and 1625481150. It features a robust steel housing with corrosion-resistant coating and a high-nitrile gasket for leak-free sealing under system pressure. The design ensures minimal pressure drop across the element, maintaining compressor energy efficiency. Recommended service interval is 8,000 operating hours or annually, whichever occurs first, as part of the 1000-hour service pack schedule. Compatible with Atlas Copco GA 18-37 VSD+ fixed and variable speed drive compressors and XATS 138 portable compressors.
