In normal temperature circumstance(under 150 C), the polyester needle felt will satisfy the bag filter systems, if the temperature on the high side, such as tail gas/fume/dust from metallurgical plant, carbon black plant, iron works(blast furnace gas), cement plant (tail gas from vertical kiln), petroleum fumes from mixing round the beton and asphaltum, coal fired boiler, etc, the normal filter method won't work. The reason as following: 1. be restricted by specific resistance, the electronic filter system won't works, so the bag filter system is the first choice for dust/fume removal. 2.if the user try to reduce the temperature(made it under 150 C), which will increase the investment and also be restricted by field. 3. just because there may contain some material such as sulfur in the gas/fume, the acid dew will exist. Aramid needle felt, besides equip the ability of spinnability, abrasion resistance, they also with the ability of high temperature resistance, flame resistance, infusibility. The fiber won't self-ignite, when the temperature up to 400 C, the aramid fiber will carbonization gradually. Besides, aramide fiber also with a good dimensional stability, long service life.
Note: 1. special specification can be customized.
2. maximum width:2.3meters.
3. both filter cloth rolls and filter bags are available from Suita Filters.
