Frequently Asked Questions
Are PTFE filter bags hydrophobic?
Yes. PTFE is inherently hydrophobic and hydrolysis-resistant—ideal for wet or high-humidity flue gas.
What’s the difference between PTFE-coated and 100% PTFE filter bags?
PTFE-coated bags use a base fabric (e.g., fiberglass) with a PTFE layer—good for moderate conditions. 100% PTFE bags (like ours) contain no other fibers, offering superior chemical resistance for extreme environments.
Can you supply PTFE bags for my pulse jet collector?
Absolutely. We manufacture PTFE filter bags compatible with all major baghouse brands (GE, FL, Donaldson, etc.). Just provide your cage dimensions.

7. PTFE filter bag has excellent filtration efficiency, low and stable differential pressure, easy cleaning, and under the same conditions its life is significantly longer than other high temperature resistant filter materials. teflon felt liquid filter bag
The structure of cloth bag dust collector is mainly composed of: upper, middle and lower parts, dust cleaning system and dust discharge mechanism. The performance of the bag filter is good or bad is in addition to the correct choice of bag material, the dust cleaning system plays an important decisive role for the bag filter. ptfe needle felt filter cloth
