Glass Fiber and PTFE Membrane Filter Bags

Glass Fiber Filter with PTFE Membrane

Xiwang glass fiber filter media with PTFE membranes are specifically developed for industrial dust collection systems operating under high temperatures, heavy dust loads, and abrasive process conditions. This product group combines the superior thermal resistance of glass fiber with the high filtration efficiency and emission control provided by the PTFE membrane.

Thanks to the PTFE membrane, filtration takes place on the filter surface. This structure prevents dust from penetrating into the filter media, ensuring lower and more stable differential pressure, longer filter service life, and high process stability. It delivers reliable and sustainable performance, especially in cement and mineral industries.
