ePTFE Membrane Needle Felt

Detail

ePTFE membrane needle felt

ePTFE embedded membrane coating for enhanced collection efficiency and dust release. Has improved chemical resistance when compared with acrylic and polyurethane.


Useing the ePTFE coated filter bag allows baghouse engineers to reduce capital and operational of cost,as well as the ability to design the baghouse for higher airflows,Use of ePTFE membrance coated filter bag also provides for a degree of protection from the"unknown" and "unpredict-able" changes that sometimes occur during baghouse operations,the ePTFE membrance is the most instances,the best economic choice for filter media, expanded many industrial operations,They are highly versatile and efficient in dust and fume collection.
