Our PTFE Membrane Needle Felt is engineered for the most demanding dust filtration applications. By laminating a microporous PTFE (Teflon) membrane onto a high-quality needle felt base, this filter media ensures surface filtration with extremely low emissions and minimal dust penetration. It is especially suited for working conditions involving ultra-fine dust, high temperatures, and aggressive chemicals. Ideal for cement kilns, power plant boilers, waste incineration systems, and chemical industries, this membrane filter extends filter life, reduces maintenance costs, and meets strict environmental regulations.
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.
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.
