Garage Fine Dust Collection System Pulse Jet Cleaning Woodworking Processing

Bags are held firmly in place at the top by clasps and are usually sewn shut at the bottom. In another design, a snap ring is sewn into the top of the bag which fits into the tube sheet opening. The cage slides inside the bag and the top of the cage sits on the tube sheet. Dust-laden gas is filtered through the bag depositing dust on the outside surface of the bag. Pulse-jet cleaning is used for cleaning bags in an exterior filtration system as well.

The filter bag is open at the top and closed at the bottom, being fixed on the tube sheet at the top. With this configuration, the dust is collected on the outside of the filter bag. The filter bag normally contains a metallic cage to keep the filter bag from collapsing. Usually a row of filter bags is cleaned simultaneously by introducing compressed air briefly at the top of the filter bag.
