High Efficiency air Filter PPS Cloth Filter Bag

PPS Felt Filter Bag:   PPS filter felt is one kind of main high temperature resistant filter mediums. Our factory have selected the polyphenylene sulfide (PPS) fiber from America and Japan and followed the other producing technology of high temperature resistant filter felt to produce it, which is the most suitable for the following occasions:

1. Favorable temperature resistance melting point 285º C, working temperature 190º C,

    Instantaneous operating temperature210º C, limited oxygen index 34~35;

2. Be suitable for the oxygen content below 15%;

3. Oxide containing sculpture in the fuel or flue gas, now it has been proved that it was the fiber of anti-acid, alkali,  abrasion and chemicals;

4. Containing moisture in the flue gas;

5. Under the condition of 190~210º C operating modes.
