P84 Filter Bags

Dewdon’s P84 (Polymide) needle punched felt filter bag is made of P84 fiber with three foliage structure imported raw material, the fiber itself has a larger specific surface area, it can Increase the contact probability of fiber and dust particles, and the efficiency of the intercepting and collecting of the dust in the flue gas is greatly improved.

Product Features

Max. operating temperature: 240℃/464℉; Ultimate temperature: 260℃/500℉.

Due to its leaf-shaped cross section, It’s 80% increase in filtration area than others filter Media.

The properties of Hydrolytic and Oxidation resistance are moderate. We suggest the water vapour content less than 35%Vol and O2 content less than 16%Vol.

Oxysulfide will shorter the service life of P84 bag, the suggestion content of oxysulfide should be less than 700mg/Nm3; the waste incinerator should have the desulfurizing unit.
