The filter bag is a key part in the operation of the bag filter. Usually the cylindrical filter bag hangs vertically in the filter. The fabric and design of the filter bag should be as efficient as possible, easy to remove dust and durable.
Dust is attached to the outer surface of the filter bag in pulse and box type pulse dust collector. When the dust containing gas passes through the dust collector, the dust is collected on the outer surface of the filter bag, while the clean gas enters into the inside of the filter bag through the filter material. The cage inside the bag supports the bag and prevents the bag from collapsing. It also helps to remove and redistribute the dust cake.
* The press cloth is filtered based on the thickness of the entire filter layer, which belongs to deep filtration
* The whole depth direction of the filter layer is formed by the fiber into a three-dimensional porous structure, from inside to outside from loose to cause
Dense, forming gradient filtration
Technical Specifications:
All of our filter bags are available in many different weights, treatments and coatings to
suit the industry application. Standard and specific media materials are:
