ECOGRACE Dust  Filter bags widely applied in different industrial dust filtration system or air pollution control system dust collector filter  elements.

ECOGRACE PTFE membrane fiberglas Filter bag ,with 260-280 degree working temperature Fiberglass Filter bag is maily applied for the metal smelting mill , cement kiln dust filration system . 

Production Description
1.Temperature (°C): Continue: 260 , Instant: 280
2.Features: Lower price compared with other high temperature fibers , and stable size,low shrinkage rate , high intensity .
3.Application: Fume Filtraiton / Ash handling system for industry like chemistry , steel factory, metallurgy, cement,etc.
Steel factory smoke treatment Fiberglass pocket filter is a high temperature resistant filter media,they are mainly used in cement plant,carbon black process of flue gas purification. With the benefits of high temperature resistance and low cost,it becomes a widely used filter material.

Steel factory smoke treatment Fiberglass pocket filter : 
puts PTFE membrane bonding to the surface of thermoplastic fiber filter material, plays the role of early powder layer to achieve surface of filter material. The membrane surface is smooth, with excellent chemical stability and good cleaning effect, greatly improving the service life of filter materials

PTFE 100% Filter Felt Air Filter Bag For Air Pollution control filter system in coal fired power generation power plant  , waste treatment power generation plant . 

Application of PTFE Filter Fabrics PTFE Filter Bag :


PTFE filter cloth Dust collector filter bags are high temperature resistant filter bag . It is widely applied in waste treatment power generation plant for air pollution control system , filter bag .

 PTFE Filter bags  are suitable for the corrosion resistance of harsh condition that require a longer working life of dust filters, such as waste incineration flue gas filtration.
As dust filter bags, it is largely used in thermal power industry, waste treatment power generation plant air pollution contorl system .
Very good chemcial resistant , anti acid , anti alkalic , anti corrossion , high temperature resistant .
Below fiber performance index for your reference.
