How high temperature can the polyester filter bag withstand in general use?

Polyester filter bag is a hard and soft fiber structure, with high substrate strength, sufficient mechanical strength, good dust removal effect, low cost, low ash strength, and low stable pressure loss. Polyester filter bag has the characteristics of high air permeability, low resistance and high filtration efficiency.

Polyester filter bag has the advantages of ordinary felt filter cloth with high porosity, good air permeability, high dust removal efficiency and long service life. The polyester filter bag is resistant to high temperature 150℃, acid and alkali, and has excellent abrasion resistance.


The polyester filter bag can be continuously 100~130℃, and the instantaneous temperature is 150℃. The polyester filter bag has good dimensional stability, high strength and low elongation. In addition, the polyester filter bag has a smooth surface, easy dust removal, low operating resistance and good comprehensive chemical resistance.


Polyester filter bags have low shrinkage, good filtration performance, corrosion resistance, and stable dimensions. They can be used for a long time at temperatures below 150 degrees, not more than 150 degrees Celsius and acid-base environments. The scope of application and restrictions on use. This filter bag product is suitable for gas Solid flow separation, high dust removal efficiency, low emission concentration and low dust ratio. Polyester filter bags are widely used. It can meet the requirements of internal and external protection and environmental protection.


The damage and abrasion of the polyester filter bag has always been an important part of the maintenance cost of the filter bag. Therefore, the polyester filter bag should pay attention to adjusting the exhaust volume of the dust collector. When the flow is large, an automatic flow control system should be added to ensure that the dust collector operates under a stable air volume. Uneven air inlets can easily cause local impacts on the bag body and cause damage to the perforations in the bag. At this time, a ventilation pipe should be installed on the air inlet, otherwise, the wear-resistant polyester filter bag needs to be replaced.
