Nomex Needled Felt Dust Collector Filter Bags 1 micron Bag Filter Nomex
Cement kiln dust collector , Asphalt mixing site , metal smelting furnace dust collector system equipped Nomex filter bag , ECOGRACE Nomex filter bag is high temperature resistant , water repellent treatment .ECOGRACE filter offer one of the best total economies in a filtration system because of higher air to cloth ratios , higher temperature resistant function , and long wearing life .
Properties
1) Performs at high temperatures
Nomex filter bag can be used continuously at operating temperatures up to 218°C (425°F) , and can handle higher temperature surges . However, to optimize dust filter bag wearing life, continuous temperatures of 204°C (400°F ) and lower with minimum temperature surges are recommended.
2) Resists flexing and abrasion
Flex resistance of Nomex filter bag at room temperature is good , about equal to that of polyester fiilters . after aging at temperatures of 121°C (250°F) and above its toughness if excellent. Nomex filter bag should give more than three times the wear life of polyester filter bags at 121°C (250°F) and above.
3) Effect of moisture
Nomex filter bag performs well at high operating temperatures with normal amounts of moisture. The wear life projections in the below graphs were developed using 6-10% H20. When operating in high moisture environments it would be worthwhile to investigate reduction of temperature to reduce wear life. 4) Resists Chemicals
Aramid filter bag fier resists attacks by mild acids, mild alkalis, and most hydrocarbons. In acid environments, evaluation of Nomex filter bags should be made to ensure that the fiber will perform acceptably before insulation. Aramid filter bag is acid environment , at temperatures above the dew point , will outperform polyester. Temperature above the dew point should be maintained to minimize chemical attack on Nomex filter bag and the dust collector equipment.
5) Dimensional Stability
Nomex filter bag ,Aramid filter bag is one of the most dimensionally stable dust filter bags available. Fibers of Nomex properly manufactured and finished, should neither stretch nor shrink over 2% when operated at temperatures up to 218°C (425°F).
6) High temperatures
The most effective use of Nomex filter bag ,aramid filter bag is in high efficiency filtering systems where effluent temperatures are above 250°F or in systems with surges over 250°F. In hot gas filtration systems.
Applications:
Nomex filter bag for higher temperature dust filtration ,widely applied in Asphalt mixing plant , cement Kiln smoke dust filtration in cement plant , steel melting furnace smoke filtration and so on .
NOMEX filter bag offer one of the best total economies in a filtration system because of higher air to cloth ratios, higher temperature capability, and a long working life.
