Introduction
Filter bag is the core of the dust filter components. The filter bag has the strict requirements on design, filter material cutting, woven technology etc. These requirements are very important for the normal operation of the bag filter and convenient maintenance, and it is great significance to enlong the service life of the filter bag.
Structure and application
Filter bag are composed by woven filter material bag body and supported in role, snap ring, clamp, chain hoist, etc. The rest of the filter bag dust collector and its accessories are the venturi tube, frame, mouth of elastic ring, etc.
Filter bag material
We can supply kinds of material of filter bag, the following are the main material:
1. Polyester(PET) filter bag, used in dust temperature lower 130 celsius working condition.
2. Nomex (aramid) filter bag, used in dust temperature lower 200 celsius working condition. like asphalt.
3. PTFE filter bag,used in dust temperature lower 260 celsius working condition. it can be used all working conditions.
4. Fiber glass filter bag, used in dust temperature lower 260 celsius working condition.
5. others, like P84, PPS
