Long-element KNT cartridge for high filter-area housings
KNT-LT is the long-length version of the KNT cartridge, used where the housing has room for a taller element and the process needs more filter area from the same tube sheet.
More pleat length means lower face velocity, which is how you bring differential pressure back into range without rebuilding the collector.
Available in the standard media range with the same end-cap and sealing options as the rest of the KNT family.

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

Air volume for model 1533LT as printed (308 / 747 m³/h) does not agree with its printed 9.3 m² filter area or with the rest of the table. The earlier edition of this catalogue prints the same values, so the inconsistency is in the source data itself — pending factory confirmation, do not quote it. Media: polyester / cellulose as standard, with aramid, PPS, PTFE coating, anti-static, flame-retardant and oil-water resistant treatments available on request. Transcribed from the printed catalogue and to be confirmed against the final technical datasheet before ordering.
