Dusty Industrial Environments
In manufacturing facilities with high airborne particulate levels, the 1 µm borosilicate micro glass fibre media captures fine dust before it reaches sensitive downstream equipment, reducing wear and extending service life.
Continuous-Duty Compressor Systems
For compressors running 24/7, the low 20 mbar differential pressure ensures minimal energy consumption while maintaining consistent filtration, helping to lower operational costs over time.
Maintenance Scheduling Simplification
By standardizing on the SPM-INF-1161 across multiple compressor brands like Atlas Copco and Kaeser, maintenance teams can consolidate inventory and simplify replacement intervals.
Temperature-Sensitive Processes
In applications where ambient temperatures fluctuate, the filter's wide operating range from 1.5 °C to 65 °C ensures reliable performance without risk of media degradation.
The SPM-INF-1161 is a direct replacement for filters used in Atlas Copco and Kaeser systems, as well as other brands listed. Check your existing filter's part number against our cross-reference list or measure the outer diameter (82.5 mm) and body height (674 mm) to ensure compatibility.
This filter uses borosilicate micro glass fibre media with a 1 µm filtration rating, effectively removing fine particles and ensuring high-quality compressed air output.
The outer diameter is 82.5 mm and body height is 674 mm. For thread details, please consult your equipment manual or contact our support team, as thread type may vary by application.
This is an aftermarket replacement built to match OEM specifications. It is not a genuine OEM part but offers a cost-effective alternative with equivalent performance.
Installation is straightforward: shut down the system, depressurize, remove the old filter, and install the new one by hand-tightening. Ensure proper sealing and check for leaks before restarting. Refer to your equipment manual for specific instructions.
