PTFE Teflon Membrane Air Dust Filter Bags

Temperature :
Application :
Sample :

The PTFE membrane filter bag is an after treatment ptfe filter bags after doing the ptfe membrane . The ptfe membrane filter bags can improve the filtration percistion to 20mg /m3 but it also increase the resistance of dust collector . 

After Surface Treatment of PTFE dust Filter Bags :

1. Ptfe Dipping : Improve the filtration precision ≤10mg/m³,  lower filtration efficiency but increase the acid-base resistance property . 

2. Ptfe film: Improve filtration precision ≤20mg/m³, can't lower the filtration efficiencyjust a small increase in acid-base resistance property


1. High Temperature resistance: up to 260℃ (572℉)

2. The Longest working life than other . Service life can reach 4-6 years at the temperature 66℃~204℃ and stable normal working conditions.

3. Excellent Anti-acid and anti-alkali resistance 

4. Excellent filter efficiency high to 99.99% 

5. Good performances of hydrolysis  and flame retardant

Application :

1. Waste Incineration Boiler 

2. Power Plant Boiler 

3. Other high temperature working conditons
