High-Precision Air Filtration
In applications requiring removal of sub-micron particles, such as pharmaceutical or electronics manufacturing, the 0.01 µm borosilicate media ensures clean air for sensitive processes.
Continuous-Duty Industrial Systems
For compressors running 24/7 in manufacturing plants, this filter maintains low differential pressure (80 mbar) to minimise energy loss while providing consistent filtration over long periods.
Maintenance Consolidation
Fleet operators using multiple compressor brands can standardise on this single filter element, simplifying inventory management and reducing downtime during replacements.
Cold Climate Operations
With a minimum working temperature of 1.5 °C, this filter suits outdoor installations in cooler environments where other filters may freeze or fail.
Check your existing filter's outer diameter (82.5 mm) and body height (820 mm). It replaces models from Atlas Copco, Kaeser, and other listed brands. If unsure, compare dimensions or contact us with your current part number.
It uses borosilicate micro glass fibre media with a 0.01 µm filtration rating, suitable for removing fine particulates and oil aerosols from compressed air.
