The operating principle of dust collector bag:the dust collector bag is the core element of the dust catcher.The impulse type of cylindrical dust collector bag is usually suspended vertically in the dust collectors.The dust gas enter the dust collector from the inlet openning and pass the guide plate.then the part of big dust paryicle is separated by inertia force and fall into the dust hopper.When the dust gas passes the filtering area of dust collector bag.the most dust is isolated on the external surface of the bag and the purified gas flow into the box through the bag,then discharge from the aie outlet.The cage is used to prevent the bags to collapse and remove and redistribute the dust cake.

The type of filter bag

The frame filter bag:These products will be customized by the end-user chart and the size.

The liquid filter bags:These products can be customized.The normal model:NO1,2,5filter bag.The filter fineness:1u m,5u m,10u m,25u m,50u m,75u m,100u m.

The dust collector bags:These products include flat filter bag,inwar bag,oval filter bag(8m),hot melt filter bag,irregularly shaped filter bag,ring-yrpe bag,anti-static ilter bag,tectorial membrane filter bag,high-temperature filter bag,glass fiber filter bags.
