Kaeser Oil Filters are high-performance spin-on or element-style filters engineered specifically to safeguard the high-precision Sigma Profile™ rotors and bearings in Kaeser rotary screw compressors. These filters feature a high dirt-holding capacity and advanced microfiber or deep-pleated media that effectively removes microscopic contaminants, metal particles, and carbon buildup from the lubricating oil. By ensuring that only clean oil is recirculated, they significantly reduce mechanical friction, prevent the clogging of downstream components, and help maintain the compressor's thermal stability. Genuine Kaeser filters are designed for low differential pressure—often up to 50% lower than aftermarket alternatives—which minimizes the load on the motor and optimizes energy efficiency. Regularly replacing these filters at the recommended 2,000 to 3,000-hour intervals is essential for maximizing equipment uptime and maintaining the long-term reliability of your Kaeser ASD, BSD, or CSD series system.
