Air Oil Separator Filters are designed to separate oil from compressed air in oil-injected rotary screw compressors. They play an important role in maintaining compressed air quality, reducing oil carryover and helping protect downstream equipment and pneumatic systems from oil contamination.
During the compression process, lubricating oil is introduced into the compressor chamber for cooling, sealing and lubrication. As a result, oil becomes mixed with the compressed air. The air oil separator removes these oil aerosols from the compressed air before it leaves the compressor, allowing the recovered oil to return to the oil circuit while cleaner air is delivered to the compressed air system.
The separation process is based on coalescing filtration. Fine oil droplets are captured within the separator media and combine into larger droplets. The separated oil is then collected and returned to the compressor through the oil return system. High-quality separator elements help achieve efficient oil separation while maintaining suitable air flow and minimizing pressure drop.
Air oil separator filters are available in different dimensions, configurations and filtration characteristics to suit various compressor models and operating conditions. Correct selection should consider compressor capacity, operating pressure, temperature, oil type and manufacturer specifications.
Regular inspection and timely replacement of the air oil separator are essential for maintaining compressor efficiency. A saturated or damaged separator can increase pressure drop, raise energy consumption and increase oil carryover into the compressed air line.
Mers Global provides air oil separator filter solutions for rotary screw compressors, including replacement and application-specific options manufactured according to required dimensions and technical specifications.
