PTFE Membrane Polyester Filter Cloth


PTFE polyester membrane filter cloth for enhanced collection efficiency and dust release.

Using the ePTFE membrane filter cloth allows bag house engineers to reduce capital and operational of cost.

Useing of ePTFE membrane polyester filter cloth also provides for a degree of protection from the” unknown" and "Unpredictably-able" changes that sometimes occur during bag house operations, the ePTFE membrane polyester filter cloth is the most instances, the best economic choice for filter cloth, expanded many industrial operations, PTFE membrane polyester filter cloth are highly versatile and efficient in dust and fume collection.

Benefit of PTFE Membrane

On a standard bag dust builds up on the outside of the bag and creates what is known as the filter cake. The filter cake actually does the filtering while the bag fabric acts only as a support for the cake. When the bags are pulsed most of the filter cake releases and the build-up of dust begins again.


Over time however, some of the dust gets embedded deep into the bag fibers. Eventually, the bags will completely plug and need to be replaced.


Conversely, when PTFE is added to the bag it acts as the filter cake. Commonly known as Teflon. PTFE is used in many different applications from cookware to outerwear and more. When a PTFE membrane is laminated to a filter bag media it can enhance the performance of both the filter bag and the dust collection system. Let’s take a closer look at how a PTFE membrane works. If we zoom in on the PTFE membrane we can see that it is actually made out of tiny microscopic holes like Swiss cheese. The holes are large enough to allow air molecules and vapors to pass through but small enough to inhibit even the smallest dust particles from getting through.

Because the membrane keeps the dust on the surface of the bag particles never get embedded in the bag fibers and the bags will not fail from plugging up. Typically PTFE membrane bags wear out before they plug up. Usually lasting twice as long as standard bag. With twice the lifespan costly change-outs and plant shutdowns are cut in half reducing maintenance costs and increasing plant production. Since the bags are not gradually plugging up over time, PTFE bags give the additional benefit of providing more consistent airflow or suction from your dust collection system.
