Normal Temperature Needle Felt Filter Bag
The normal temperature needle felt filter bag is made from a combination of glass fiber and chemical fiber. It is known for its excellent abrasion resistance and high tensile strength. The working temperature of the needle felt filter sock bag is 150°C, though it can work at temperatures as high as 180°C for short periods of time. Filtertex’s filter bag is suitable for smoke and fume filtration in industries that have high requirements for dust extraction and air quality.
