The PTFE membrane filter material
The PTFE membrane filter material for dust filtration is made of e-PTFE membrane laminated on various synthetic fiber filter felt or glass fabrics. They provide an excellent combination of filtration efficiency and near zero emissions.
Features: Excellent efficiency, increased air flow, decreased pressure drop, dust cake release, thermal stability and durability etc.
Application: cement, paint coating, petrifaction plastic, food, metallurgy industry dust collectors and processing, lowest overall maintenance and operating costs.
