Heat Resistant Needle Felt Dust Collector P84 Filter Bag
P84 Filter Bag Introduction:
P84 (polymide) dust collector filter media displays excellent stability under dry high heat temperatures, has great filtration properties, and performs well even under elevated levels of moisture content. These are some of the reasons P84 is one of the more expensive filter medias used in pulse jet baghouse dust collectors. Industries that use P84 filter media range from waste to energy, power, and cement.
P84 filter bag is non-flammable and no hydroscopic. This felt offers extended bag life in low pH applications
and helps reduce differential pressure across the baghouse. P84 operates will in high temperature applications,
against acid attacks and is resistant to flex abrasion (unlike Fiberglass).
Alkaline should be avoided at high temperatures with using P84.
The P84 yarn is special in that it has a three-leaf cross section. This makes P84 an excellent filter for fine dust.
P84 Filter Bag Advantage:
Excellent stability in applications with high dry heat temperatures, mineral acids and alkaline.
P84 Filter Bag Disdvantage:
Must oversize bag for shrinkage that can occur in temperatures above 450 Degrees F.
