Dust Filtration >> Bags  >> Pulse jet filter bag

ST Filter manufactures various of pulse-jet filter bags.

The dust-load air enters through the base or side of the pulse jet filter bags, and then distributed between the filter bags in bag house. The dust is deposited on the outside surface of the filter bags, and the air flow from the outside of the bag to inside. The bags are supported by cages to prevent the bags to collapse.
 
The bags are sewn with 3 - needle chain stitch or welded vertical seam. Top constructions can be snap band, smooth raw edge, flange top, soft rope, steel ring or circle felt etc… Bottom of the bag has a round disc bottom. Bottom or middle reinforcement is to prevent bag-to-cage or bag to bag abrasion for some long bags.
