Standard KNT cartridge, a direct replacement for OEM elements

KNT-ST is the standard KNT element: the shape most collectors use straight from the factory.

It is the drop-in replacement we quote most often when a customer sends us a used element or a housing drawing.

Same media range, same sealing options, same end-cap choices as the rest of the family.

Series: KNT-ST
Models: 16 variations
Lead time: Confirm on enquiry

Construction & features

Moulded end capsInjection-moulded end caps hold the pleat pack in shape and take the venturi or threaded connection your housing uses.
Support bandsStainless steel bands lock the pleats in place and keep the cartridge round under repeated pulse cleaning.
Open inner coreA high open-area core carries the airflow with low resistance and keeps the media evenly loaded.
Sealing ringEVA or rubber sealing rings seat the cartridge into its tube sheet so unfiltered air cannot bypass the media.

Typical applications

Dust collectors and powder recovery units
Welding, cutting and grinding extraction
Shot blasting and surface preparation
Spray booths and finishing lines

Media: polyester / cellulose as standard, with aramid, PPS, PTFE coating, anti-static, flame-retardant and oil-water resistant treatments available on request.
