Polyester non woven felt is the most widely used filter material for normal temperature dust collection because of its versatile property and high cost-effectiveness. Hongyuan's Polyester needle felt filter felt is made out by long filament scrim, and fine fiber needle punching on the surface, in suitable density and thickness to ensure the optimal filtration efficiency and tensile strength.
Various finishing including water and oil repellent, anti-static, PTFE membrane laminated, etc to meet your different application working conditions.
