Use cases & applications
High-Dust Environments
In construction or mining sites where airborne particulates are abundant, the 3 µm borosilicate media captures fine dust before it enters the engine, extending service intervals and protecting downstream components.
Continuous-Duty Operations
For generators or compressors running 24/7, the 5 bar collapse pressure ensures the element maintains structural integrity under sustained pressure spikes, reducing unplanned downtime.
Fleet Maintenance Consolidation
Workshops servicing multiple brands can stock this separator as a single part number that cross-references Airman, Fai Filtri, HiFi Filter, Noitech, Oxfil, and Sotras, simplifying inventory management.
Remote Site Replacements
When operating in isolated locations, the robust construction and standardised dimensions allow easy field replacement without specialised tools, minimising equipment downtime.
