Product Overview

Aramid filter bags, also known as aramid dust collector filter bags or Nomex filter bags, are high-temperature industrial filter bags designed for demanding dust collection applications.

Aramid fiber provides a combination of high-temperature resistance, mechanical strength and dimensional stability, making it suitable for industrial filtration systems operating at temperatures beyond the practical range of standard polyester filter media.

Aramid filter bags are widely used in industrial baghouses, pulse jet dust collectors, asphalt plants, cement processing, steel and metallurgy, industrial boilers and high-temperature flue gas filtration systems.

The actual operating temperature and chemical resistance depend on the specific aramid media, gas composition, oxygen concentration, humidity and process conditions.
