Atlas Copco 5590011541 Breather Filter Element

The 5590011541 breather filter element is designed for Atlas Copco and Epiroc air compressor lubrication and filtration systems. It functions as a crankcase breather to maintain pressure equilibrium while preventing ingress of contaminants. The filter element utilizes a pleated filter paper media housed in a carbon steel frame for structural integrity. It is a direct replacement for OEM part numbers 5590011541 and 6060002589, and cross-references to Hifi SA12978. This component is engineered for heavy-duty mining, construction, and industrial compressor applications where reliable filtration and pressure regulation are critical for equipment longevity. Technical specifications include an inner diameter of 42.8 mm and an overall length of 51 mm. The filter element weighs approximately 0.3 kg. It is constructed from carbon steel and filter paper media suitable for oil mist separation and particulate capture in compressor crankcase ventilation.
