DWD Acrylic (ePTFE membrane) needle punched dust filter bag is made of high quality fine denier fiber yarn. It is produced by advanced imported equipment, mixing fibers in certain textile, finishes with various processing to improve filtration and quality.

In same working condition, the filtration efficiency of acrylic PTFE membrane is twice than ordinary filter bag, and the service lifetime is prolonged by 4/5, and the cake release efficiency is increased by 86%.

Application:

Acrylic needle-punched felt filter bag is the most comprehensive, most cost-effective and most widely used in medium temperature filter material in industrial filtration, it is widely used in mining, cement, steel, nonferrous metals, ceramics, Quarrying and plastics industries.
