P84 is mainly used for flue gas purification in asphalt mixing, cement kilns, drying, combustion, smelting, various industrial kilns, coal-fired boilers and waste incineration , and is widely used in processes with high emission concentration requirements.
A P84 Filter Bag is a high-performance industrial filtration solution made from polyimide (P84) fiber.The filter bag is engineered for high-temperature dust filtration in waste incineration, cement production and chemical process industries. The unique trilobal fiber cross-section of P84 provides a larger surface area that is resulting in superior filtration efficiency and lower emissions compared to conventional materials.
Our senotay’s P48 filter bag is specially developed for demanding filtration environments. P84 filter bags offer outstanding resistance to thermal oxidation, acid gases and fine particulate matter.That is making them the ideal choice for waste incineration filters and flue gas purification systems.
