P84 Filter Bag

What is a P84 Filter Bag?


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.

Superior Micro-Particle Capture: The SENOTAY P84 Filter Bag


Achieve flawless emissions control and low operational pressure drops in demanding thermal environments with the SENOTAY P84 (Polyimide) Filter Bag Series—the ultimate high-efficiency filtration solution from Hebei OuTai Environmental Protection Equipment Co., Ltd. (SENOTAY). P84 fibers feature a unique, highly irregular multi-lobed (trilobal) cross-sectional structure. This specialized irregular profile increases the effective filtration surface area by up to 80% compared to round fibers, trapping microscopic dust particles directly on the bag's surface rather than allowing them to penetrate deep into the felt.

Engineered to operate continuously at temperatures up to 240°C (464°F), SENOTAY P84 filter bags deliver exceptional surface filtration efficiency and outstanding dust cake release, making them the premier choice for plants processing fine, abrasive, or challenging particulate matter.
