High Dust Environments
In facilities with high airborne particulate levels, such as woodworking or cement plants, this filter's 1 µm borosilicate media captures fine dust before it can damage downstream equipment, reducing wear and maintenance frequency.
Continuous Duty Operations
For operations running compressors 24/7, the low 20 mbar differential pressure minimises energy loss while maintaining consistent filtration, helping to keep production lines running without interruption.
Maintenance Scheduling Optimisation
Using a filter with a known 665 mm height and 83 mm outer diameter allows maintenance teams to plan replacements accurately, reducing unplanned downtime and simplifying inventory management.
Multi-Brand Fleet Consolidation
If your facility uses both Atlas Copco and Kaeser compressors, this single filter cross-references to both brands, allowing you to stock one part for multiple machines and streamline your supply chain.
Check your compressor's manual or existing filter for the dimensions: total height 665 mm, outer diameter 83 mm, and smallest inner diameter 57 mm. If these match, the filter is compatible. For Atlas Copco or Kaeser equipment, this part is a direct replacement.
This filter uses borosilicate micro glass fibre media with a filtration rating of 1 µm. It is designed to capture fine particulates and oil aerosols, providing high-efficiency filtration for compressed air systems.
The filter has an outer diameter of 83 mm, a smallest inner diameter of 57 mm, and a total height of 665 mm. These dimensions ensure it fits standard filter housings; however, specific thread details are not provided, so verify your housing's connection type.
This is an aftermarket replacement built to match OEM specifications for Atlas Copco and Kaeser filters. It is not a genuine OEM part but offers equivalent performance at a lower cost, with a 30-day money-back guarantee.
Turn off the compressor and depressurise the system. Remove the old filter by unscrewing the housing bowl. Insert the new filter, ensuring it seats properly, then reassemble the housing. Tighten securely but do not overtighten. Check for leaks before restarting.
