WEBLAST manufactures both the filter cartridges type and filter bags type dust collectors. The collectors are configured according to 2 main flows patterns.
| Dusts flow into the collector at the hopper |

Bag Type Dust Collector for Industry
Bag type dust collector systems generally fall into one of the following categories:
- Pulse jet cleaning system
- Shaker cleaning system
In Pulse jet system, the dust is collected on the outside of the filter bag and clean air exits through the inside of the bag. The bag is supported by wire cage to prevent the bag from collapsing during operation.
The filter bags are usually on a ‘Top Load’ system during installation. Access opening is provided at the top of the collector unit for removal & installation of filters.

Filter Bag Medias Options
Generally pulse jet system utilizes needle felt media while shaker system use woven clothes material. Medias are manufactured from a variety of manmade fibers and are selected based on a number of factors including: operating temperature, chemical components in the dust stream, abrasion of dust being handled, as well as other characteristic of the system. A number of treatments are available to improve dust discharge on the cleaning cycle, improve the filter efficiency, to add flame retardant qualities and other specialized applications.
