2.2mm 260 Degree PTFE Scrim Pulse Jet Dust Filter Bags

The pulse-jet or reverse-pulse baghouse is ubiquitous in industrial dust collection. These industry workhorses boast no moving parts in their basic configurations and allow collection efficiencies greater than 99.9%. In the pulse jet dust collector, the dusty airstream usually enters from below the bags or filters and is pulled upwards through the filters where dust is captured on the exterior surface and clean gas passes through to the clean air plenum side for exhaust. When fabric filters are used, the bags are supported by internal wire cages. The pulse-jet cleaning cycle is controlled by a solid-state timer which sequentially pilots “pulses” of compressed air in the reverse direction of filtering, into blow pipes mounted above each row of filters. When activated, the reverse pulse air pulses travel down the length of each bag in the given row, causing a ripple effect, dislodging and releasing the caked dust into the hopper at the base. A main advantage of the pulse jet baghouse is that it does not have to be taken off-line to clean the filters. With the dust removal programmed for regular or on-demand intervals, the system offers more complete cleaning and reconditioning of the filter bags than the other systems. Operating costs are minimal outside of the cost for compressed air for cleaning.

There are a few commonly used industrial dust collector filter bag medias used with industrial dust collectors. Polyester, Aramid, Fiberglass, P84, and PTFE are all common options that are available at different price points and have varying characteristics such as maximum operating temperature, resistance to chemicals and acids, ability to withstand abrasion and more.

How to choose the filter bag ?

The filter bag plays a key role in the dust-cleaning process, so it is very important to do the filter selection, which should be based on its performance and the nature of the smoke, so as to have a rational and optimized scheme.
