Product Features

  • The surface layer of the filter bag is made of polyester fiber and conductive fiber which can significantly improve the composite fastness, overall strength and anti-static properties of the filter material.


  • PTFE microporous membrane is used to reduce the pore size, increase high porosity and ensure high filtration precision. The filter material is treated by PTFE impregnation, which can improve the waterproof and oil proof performance.


  • The filter material adopts high-quality polyester fiber which has good jitter performance when cleaning the dust and the dust is easy to peel off. It has the advantages of high porosity, good air permeability, high dust collection efficiency and long service life.


  • Automatic cutting can ensure no deviation in size and three chain stitches can prevent the bags from being blown out.


Erection Procedure

Transporting the whole carton of filter bags into the air purification chamber through the manhole door. The filter bag must be transported in the whole carton otherwise the filter bag is easy to be scratched.
The whole carton of filter bags shall be stacked neatly in the air purification chamber.
Distributing filter bag installation protective sleeves to filter bag installation workers.
Putting the filter bag protection sleeves into the tubeplate holes.
Inserting all the filter bags into the tubeplate holes and taking out the protective sleeves.
Bending the elastic ring of the filter bag with both hands. The groove of the outer bag mouth is aligned with the edge of the tubeplate hole. The bag ring is tightly attached to the tubeplate in the whole circle and evenly tensioned.
Usually, a "snap" sound can be heard, which means that the opening of the filter bag has been clamped with the tubeplate hole. If it is not clamped, press it by hand or gently tap the periphery with a rubber hammer until it is tensioned.
Please notice to install backward from the tail end of the jet pipe to the manhole door, which can avoid workers from stepping on the elastic circlip of the filter bag.
