Aramid / Nomex Filter Bags

The aramid filter bag is a high temperature filter product; it is made of imported aramid fibers. Normal maximum continuous operating temperature is 375°F. General applications for Aramid felt include highly abrasive dust applications, cement kiln, 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.
