Use cases & applications
High-Moisture Compressed Air Systems
In environments where compressed air contains significant moisture or oil aerosols, the 0.01 µm borosilicate micro glass fibre media effectively coalesces and removes these contaminants, protecting downstream equipment from corrosion and fouling.
Continuous-Duty Industrial Operations
For facilities running compressors 24/7, the low 80 mbar differential pressure minimises energy loss, reducing operating costs while maintaining consistent filtration over extended periods.
Multi-Brand Fleet Maintenance
If your plant uses compressors from Alup, Atlas Copco, Boge, and Kaeser, this single filter element simplifies inventory management, as it fits across all these brands without needing separate stock for each.
Cold-Environment Installations
With a minimum working temperature of 1.5°C, this filter is suitable for unheated compressor rooms or outdoor installations in cooler climates, ensuring reliable performance even in low-temperature conditions.
Frequently asked questions
How do I confirm this filter fits my specific compressor model?
Check your current filter's part number against the cross-referenced brands: Alup, Atlas Copco, Boge, Donaldson, HiFi Filter, Kaeser, Mann-Filter / Mann & Hummel, Noitech, Omega Air, Oxfil, Sotras, and Ultrafilter. If your existing part matches one of these, this filter is a direct replacement.
What is the filtration rating and media type?
The filter uses borosilicate micro glass fibre media with a filtration rating of 0.01 µm, which captures fine particles and aerosols down to that size.
What are the dimensions and thread size?
The body height is 760 mm and outer diameter is 140 mm. Thread specifications are not provided; please verify compatibility with your housing.
Is this an OEM or aftermarket filter?
This is an aftermarket replacement built to the original dimensions and ratings. It is not branded as genuine or OEM but offers equivalent performance at a lower cost.
How often should I replace this filter?
Replacement intervals depend on operating conditions and air quality. Monitor differential pressure; replace when it exceeds the initial 80 mbar by the manufacturer's recommended limit for your system.
