Product description

High Temperature Nomex Needle Punched Felt Filter Bags
Overview:
Meta-Aramid Nomex dust filter bags fire retardant filter cartridge which made of aramid needle felt is a high temperature filtration media used in pulse jet bag house dust collectors. The filter bags maintain high strength, high abrasive resistance. The filter cartridge also has excellent dust release properties and resists attacks from many chemicals found in industrial smoke and fumes.

The Nomex needle punched felt has excellent high temperature resistance and flame retardancy. Its raw material is a felt made of Nomex short fibers combined with a high frequency, high density, high speed needle press. It also has non-toxic, and good electrical and mechanical properties.


Application:
Asphalt mixing, non ferrous metal refining, cement, quarrying, lime, foundry, smelting, gypsum and chemical industry.


Features:

1. The surface of the PTFE film is smooth and chemically coated, and it is laminated to the surface layer of the ordinary filter material, and the dust can be completely trapped on the surface of the film to realize surface layer filtration;

2. The Nomex needle punched felt has high porosity, and does not change the porosity after cleaning, so the dust removal efficiency has been high;

3. The use of the cleaning dust pressure is low, thereby improving the service life of the filter material, which can significantly reduce the maintenance and repair workload of the dust collector, and reduce the operating cost of the product;

4. The film filter material also has chemical stability, heat resistance and chemical resistance.
