Product Description


Our ePTFE filter membrane is made of imported PTFE resin, we can adjust the pore size, pore size distribution, porosity through a special process, so that the wind resistance and efficiency can be adjusted freely. It can laminated with various nonwoven fabric which is widely used in vacuum cleaner folded filter. The efficiency can reach European standard H11, H12, H13.
Additionally, the membrane has special characteristics of breathable, chemical stability, small friction coefficient, high temperature resistance etc. It is also widely used to laminate with PP felt, polyester PPS, Nomex needle felt, glass fiber needle felt etc. The dust collect rate could be above 99.9%. It’s the best choice for any kind of high efficiency air filter.
