Product Overview

High Temperature Nomex Filter Bags (Aramid Filter Bag Media) are crafted from high-performance textile filter cloth and non-woven felt. These bags utilize advanced fiber fabric filtering actions to effectively trap dust-containing gases in demanding environments.

1. Ambient Bags: Made of polyester, polypropylene, or acrylic. Features excellent air permeability, smooth surfaces, and dimensional stability. Ideal for general industrial dust removal at normal temperatures.

2. Medium-Temperature Bags: Utilizes aramid or PPS fibers with specialized treatments (waterproof, anti-oil, anti-corrosion) to handle more severe working conditions.

3. High-Temperature Bags: Constructed from high-strength fibers like P84, expanded glass fiber, and ultra-fine glass fiber. These offer superior thermal stability and long service life for extreme flue gas conditions.

Frequently Asked Questions

1. What are the primary materials used in Nomex filter bags? Our bags are primarily made of Nomex (Aramid) fibers, but we also offer Polyester, P84, PTFE, and PPS depending on the specific filtration environment and temperature requirements.

2. What is the maximum operating temperature for Nomex bags? Nomex filter bags can operate at a continuous running temperature of 200°C, with a peak temperature tolerance of up to 240°C.

3. Can these filter bags resist chemical corrosion? Yes, materials like PTFE and PPS offer excellent resistance to acids and alkalis. Nomex itself provides good alkali resistance and fair acid resistance.

4. What type of installations are available for the bag tops? We provide various top constructions including snap bands, rings, double beaded tops, and raw edge tops for side loading.

5. Are custom sizes available for industrial dust collectors? Absolutely. We offer customized diameters (standard 4" to 6.62") and lengths ranging from 18" up to 192" to fit specific pulse jet bag dust collectors.

6. What is the typical service life of these filter bags? Under normal operating conditions and proper maintenance, the service life is approximately one year.
