PTFE Filter Bag For Dust Collecer
The dust collector bag is the core element of the cylindrical impulse type dust collector bag is suspend in the dust collectors vertically.
Dust gas enters the dust hopper directly by inertia. When dust gas enters the dust collector bag from the air inlet and the passage board, making most big dust particle filtered out into the dust hopper directly by inertia. When dust gas reaches the filtering area of the box with dust collector bags , most dust is cap tured on the outer surface of the dust collector bags, and the gas flows into the pocket through filter. Media then purified gas discharges from the outlet.
The cage inside the pocket is used to support and prevent the pocket to collapse while it is helpful to remove and redistribute the dust cake.

PTFE needle felt is a kind of filtration material made of PTFE with a three-dimensional needle.
PTFE fiber to the linear macromolecule structures, thus has good heat resistance, abrasion resistance, corrosion resistance, chemical stability and widely used in steel, power, waste incineration and flue gas side of the bad environment.
