RAM Filters

This pre-filter range is equipped with our CFT 18 mm tube to yield ultra-high pre-filter efficiency in extreme dust conditions due to the axial inlet and outlet flow that minimizes pressure gradient. These pre-filters maintain high efficiency even in variable flow conditions due to the exceptional high turndown ratio of these tubes.


These pre-filters are manufactured from Aluminum sheet metal that is powder-coated inside and out to ensure longevity and ability to meet and exceed the demands associated with tough mining conditions.


The interface of these pre-filters is designed to require no fabrication during installation. Daily maintenance is not required unless the dust bowl reaches its “Full” level.




Passive scavenge by means of serviceable dust bowl


  • Vastly extends media filter life, which enables extended service intervals.

  • Reduce labor costs.

  • Reduce cost of ownership of equipment.

  • Reduce possible engine failures due to possible incorrect fitment of media filters.

  • Could reduce silica contaminants in oil, if filtration management is kept at a high level.

  • No moving parts in pre-filter unit.

  • Ideally suited for fitment on secondary equipment, like Graders, Loaders, ADT’s etc
