Dusty Industrial Environments
In facilities with high airborne dust levels, such as woodworking or cement plants, this filter's 1 µm borosilicate media captures fine particles effectively. Its low differential pressure of 20 mbar helps maintain energy efficiency, reducing strain on the compressor.
Continuous-Duty Compressor Operations
For compressors running 24/7 in manufacturing lines, this filter provides consistent filtration with minimal pressure drop. The robust construction withstands continuous operation up to 65 °C, extending service intervals.
Maintenance Consolidation for Mixed Fleets
Facilities using both Atlas Copco and Kaeser compressors can standardise on this single filter, simplifying inventory management. Its cross-reference compatibility reduces the need for multiple part numbers, streamlining procurement.
Cold Climate Installations
With a minimum working temperature of 1.5 °C, this filter suits outdoor compressor installations in cooler climates. It remains functional in unheated areas without risk of media damage, ensuring reliable filtration year-round.
Check your compressor's original filter part number against our cross-reference list, which includes Atlas Copco and Kaeser. If your model is not listed, measure the outer diameter (82.5 mm), smallest inner diameter (57 mm), and total height (525 mm) to verify fit.
The filter uses borosilicate micro glass fibre media with a 1 µm filtration rating. This media is effective at capturing fine particulates, including oil aerosols and dust, down to 1 micron in size.
The filter has an outer diameter of 82.5 mm, smallest inner diameter of 57 mm, and total height of 525 mm. The body height is 518 mm with a 7 mm additional height. Thread details are not specified, so check your existing filter's thread type.
No, this is an aftermarket filter built to the original dimensions and ratings. It is a direct replacement for Atlas Copco and Kaeser filters, offering equivalent performance at a lower cost. It is not manufactured by the original equipment brand.
Installation is straightforward: remove the old filter, clean the housing, and screw the new filter into place hand-tight. Ensure the O-ring seals properly. No special tools are required. Refer to your compressor manual for specific instructions.
