At VIFICO, customers will be supported to survey, consult and provide free samples. All dust filter fabrics are imported 100% from reputable, quality and selected suppliers, VIFICO provides full documents of CO and CQ import. Dust filterbags are produced on a European standard technology line, reaching a capacity of more than 20,000 products/ months with a staff of many years of experience in the industry.
Polyester dust filter bags produced from Polyester non-woven dust filter cloth are white, capable of withstanding temperatures from 130oC to 150oC, high abrasion resistance, good oxidation resistance. However, Polyester dust filter bag life will be affected by the water content in the exhaust gas when working at high temperatures. Therefore, humidity control of flue gas and compressed air used to wash clean dust is one of the necessary conditions to use dust filter bags effectively. Polyester is the most popular material used in the industrial dust filter industry today because of its flexibility and low cost, economic efficiency and high dust treatment.
E.g.
- Efficientindustrial dust recovery/ disposal PE bags.
- Dust with high cohesion, PE bag for moisture-proof surface treatment.
- Fine dust <2.5 microns, acidic or alkaline, low emission concentration requirements, selection of PE bags produced from small diameter fibers, fabric weight from 550 - 600g/m2 , PTFE membrane treatment...
In Vietnam, Polyester dust filter bags are used in all industries that generate dust in some or all production stages such as:
- Construction materials: Cement, Steel, Gypsum, Ceramic tiles...
- Mining and mineral processing industry: Stone powder, Sand, Glass, Alumina, Non-ferrous
metals...
- Food and feed industry, Pharmaceuticals, Tobacco- Other industries: Wood, Fertilizer, Battery, Tire, Plastic, Waste treatment, Boiler, Thermal power, Hot asphalt...etc.
