Aramid Felt (common brand: Nomex®) Normal maximum continuous operating temperature is
375°F. General applications for Aramid felt include: highly abrasive dust applications, electric arc
furnaces, high temperature dryers, cupolas, and chemical applications where high temperatures
exist. Aramid offers a good resistance to alkalis under most condition. Most mineral oxides cause
degradation and partial decomposition. Aramid withstands common organic solvents very well. Some phenolic compounds cause solubility.
Fiberglass (Woven) (FG)– Normal continuous operating temperature is 500°F. General applications include: cement kilns, high temperature dryers, carbon black reactors, power plants, and electric furnaces. Fiberglass has excellent resistance to most acids, but is attacked by hydrofluoric acid. Not recommended where bases and salts such as chlorides, bromides, and cyanides are present.This media has poor flex abrasion qualities and requires a 20 vertical wire minimum support cage when used in tubular filter bag form.
P-84® (Felt) (PM) – Normal continuous operating temperature is 500°F. Common applications
include: smelters, dryers, coal-fired boilers, incinerators, kilns, and calciners. P-84® is non-flammable and no hydroscopic. This felt offers extended bag life in low pH applications and helps
reduce differential pressure across the baghouse.
