Vacuum filtration, factory-direct
Filter elements are consumables, replaced on every service cycle. Northkai gives service shops and system builders a lower-cost second source that fits existing housings and routines — no retraining, no fit risk.
-
Medical vacuum filters — ATS brand
For medical and dental vacuum systems, where filtration is a scheduled consumable on every maintenance visit.
-
Inlet filters — direct-match for the CSL series
Replacement inlet filters dimensionally matched to the widely installed CSL series. Same fit, same change-out routine.
-
Coalescing filters
Elements that strip oil mist and fine aerosols from vacuum and compressed-air streams, keeping discharge air clean.
-
Activated carbon filters
Odour and vapour removal on vacuum and exhaust lines — the polishing stage where smell or chemical carry-over matters.
-
Regenerative blower silencers — direct-match for the SLCR series
Silencers dimensionally matched to the widely installed SLCR series — same fit on the blower installations you already service.
Send the part number of the filter you replace most often and we'll quote it against your current cost. Full pricing and datasheets are shared on serious customer request.
