The filter bag made of needle felt with PTFE membrane is made of PTFE microporous film laminated with needle-punched felt and film through a special process of thermal lamination. The surface is smooth, the dust is easy to peel off, and the dust is cleaned thoroughly, which reduces the possibility of dust compaction after forming a powder layer on the surface of the filter bag. The filter material with PTFE membrane not only maintains the inherent high chemical stability of PTFE, low friction coefficient, high and low temperature resistance, anti-aging, etc., can resist tiny particles, but also has incomparable air permeability of general coated filter materials , waterproof and other characteristics. It has excellent anti-condensation function, especially for environments with high concentration, high humidity, dusty gas, high adhesion dust, and high emission requirements.
Using the filter bag with PTFE membrane, the dust cannot penetrate into the filter material, but is only filtered on the surface. Whether it is coarse or fine dust, it is all deposited on the surface of the filter material. The filter material is intercepted by the pore size of the film itself. In the initial filtration period, it is effective filtration from the beginning of use, and it is in filtration nearly 100% of the time.
The filter bag made of needle felt with PTFE membrane is a new type of post-processing technology that is more advanced than the filter bag with water-proof and oil-proof treatment. Treating the surface of the filter material with PTFE membrane not only solves the problems of anti-condensation and sticky bags, but also has greatly improved the filtration effect of the dust collector bag. Now many filter occasions that require ultra-low emissions for environmental protection generally require the dust collector bag to be treated with PTFE membrane. In places with high humidity, the use of filter bag with PTFE membrane will have a better effect than conventional water-repellent and oil-proof dust collector bags.
