P84 (Felt) Normal continuous operating temperature is 260degrees.
Common applications include: smelters, dryers, coal-fired boilers, incinerators, kilns, and calciners.
P84 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.
