Dust Collector Polyester Needle Felt Filter Bag
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.

lNeedled punched nonwovens is using staggered and spatial uniformity of cloth, making with polyester staple fiber and polyester yarn, then after-processing for hot-rolled, singeing and coating to make surface smooth and easy
lThe material, which is large voids, good permeability, widely use and high chemical stability, can be widely used in filter water, oil and other liquid solid separation, especially normal temperature gas and acidic and basic gas.
