PTFE Membrane Filter Bag

In industries where efficient filtration is critical, the PTFE Membrane Filter Bag stands out for its superior performance. Engineered for demanding applications, this filter bag offers exceptional dust release properties and high filtration efficiency. For environments requiring static control, our Industrial Anti Static Dust Filter Bag provides reliable protection against electrostatic discharge. Similarly, Anti-static Dust Collector Bags are ideal for dust collection systems where safety is a priority. When comparing materials, the Woven Fiberglass Filter Bag offers excellent temperature resistance, while the Nonwoven fabric filter Bag is known for its cost-effectiveness and versatility in various filtration tasks.


The PTFE Membrane Filter Bag is designed with advanced polytetrafluoroethylene (PTFE) membrane technology, which ensures minimal pressure drop and extended service life. This filter bag is highly resistant to chemicals, moisture, and high temperatures, making it suitable for harsh industrial environments. Key parameters include a filtration efficiency of up to 99.99% for sub-micron particles, operating temperatures ranging from -100°F to 500°F, and excellent permeability. Below are the detailed specifications presented in a list and table for clarity.
