Oil Vapour Removal in Critical Applications
In environments where oil-free air is essential, such as food processing or pharmaceutical packaging, this activated carbon filter eliminates oil vapour and odours, ensuring air quality meets stringent standards.
Continuous-Duty Industrial Compressors
For compressors running 24/7 in manufacturing plants, this filter's robust construction and 60 mbar differential pressure maintain consistent flow with minimal energy loss, reducing operational costs.
Maintenance Scheduling for Multiple Units
When servicing a fleet of Atlas Copco compressors, standardising on this aftermarket filter simplifies inventory management and replacement intervals, as its dimensions and media are consistent across compatible models.
High-Temperature Compressed Air Systems
In hot climates or near furnaces, where compressed air temperatures can reach 45 °C, this filter's temperature rating ensures reliable filtration without media degradation.
Check your compressor's filter housing dimensions: outer diameter 87 mm, largest inner diameter 52 mm, smallest inner diameter 10 mm, and overall height 770 mm. If these match, SPM-INF-1281 is a direct replacement.
Activated carbon filters remove oil vapour, hydrocarbons, and odours from compressed air, but they do not remove particulates or water. A particulate pre-filter is recommended upstream.
This filter does not include threads; it is a drop-in cartridge with a largest inner diameter of 52 mm and smallest inner diameter of 10 mm. It fits housings with matching internal dimensions.
No, this is an aftermarket replacement built to match OEM specifications. It is not manufactured by Atlas Copco but is designed to fit and perform equivalently in compatible systems.
Replacement frequency depends on operating conditions and air quality requirements. Typically, activated carbon filters are replaced when differential pressure exceeds 60 mbar or when odour breakthrough is detected.
