Plenum Pulse and Pulse-Jet bag top and bottom designs
Pulse-jet and plenum pulse baghouses collect dust on the outside of the filter. Dust-laden gas floods the baghouse, and clean air exits through the inside of the bag while the dust particles collect on the outside filter surface.
A support cage prevents bag collapse during filtration and aids in the re-distribution and cleaning of the dustcake. A wide variety of filter bags can be manufactured to meet specific application needs.

Sleeve Top is a separate piece of fabric sewn onto the bag body so that it extends beyond the bag body. These are used in lieu of a raw edge to prevent puckering when folding the bag into the cage.

Disc Bottom bags have a round or oval enclosure attached to the bag body, using an overlock stitch on felts and lock stitch on wovens. Two-ply discs are traditionally sewn to woven glass bags.
A Tuffskirt is a separate piece of fabric sewn around the bag body with a portion of the fabric extending below the disc to help protect it from wear and inlet abrasion.
A Wearstrip is a separate piece of fabric sewn around the bag body. This fabric piece helps prevent bag-to-bag and bag-to-cage abrasion. |
