Dusty Industrial Environments
In workshops or factories with high airborne dust levels, the 1 µm borosilicate glass fibre media captures fine particles before they reach downstream equipment. This reduces wear on pneumatic tools and valves, extending their service life.
Continuous-Duty Compressor Stations
For compressors running 24/7, the low differential pressure of 20 mbar minimizes energy consumption while maintaining consistent filtration. Operators can rely on stable air quality without frequent filter changes.
Seasonal or Remote Operations
In facilities with variable demand, such as seasonal manufacturing or remote mining sites, the filter's robust construction withstands temperature swings from 1.5 °C to 65 °C. This ensures reliable performance even when equipment is left idle.
Consolidating Filter Inventory
If your site uses multiple brands like Atlas Copco, Hiross, or Omega Air, this single aftermarket filter replaces several OEM part numbers. This simplifies stock management and reduces the number of spare parts you need to keep on hand.
Check your compressor's filter housing dimensions: the SPM-INF-1257 has an outer diameter of 62 mm, smallest inner diameter of 32 mm, and total height of 235 mm. Compare these against your current filter. If they match, it is a direct replacement.
The filter uses borosilicate micro glass fibre media with a filtration rating of 1 µm. This provides high-efficiency capture of solid particles and oil aerosols down to 1 micron in size.
The body height is 225 mm with an additional 10 mm for a total height of 235 mm. Outer diameter is 62 mm and smallest inner diameter is 32 mm. The filter does not have threads; it is a drop-in element with a sealing gasket.
This is an aftermarket filter, not a genuine OEM part. It is built to match OEM specifications and serves as a direct replacement for filters used in Atlas Copco equipment and cross-referenced brands like Hiross and Omega Air.
Turn off the compressed air system and depressurize the filter housing. Remove the old filter element, clean the housing interior, and insert the new SPM-INF-1257. Ensure the sealing gasket sits properly before closing the housing. No special tools are required.
