Fiberglass Bag / Pocket Filter

The fiberglass pocket filter utilizes specialized ultra-fine glass fiber media and a multi-pocket construction to increase filtration surface area and dust-holding capacity, enabling efficient capture of PM10 and PM2.5 particles while maintaining a low pressure drop. Furthermore, the filter features a construction comprising a rigid frame, multi-pocket glass fiber media, and internal reinforcing supports, ensuring excellent high-temperature resistance, corrosion resistance, and long-term operational stability.
