PTFE membrane needle felt
PTFE embedded membrane coating for enhanced collection efficiency and dust release. Has improved chemical resistance when compared with acrylic and polyurethane.
Using the ePTFE coated filter bag allows bag house engineers to reduce capital and operational of cost, as well as the ability to design the bag house for higher airflows, Use of ePTFE membrane coated filter bag also provides for a degree of protection from the” unknown" and "unpredicted-able" changes that sometimes occur during bag house operations, the ePTFE membrane 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.
Needle felts we made can be treated with PTFE membrane.
