Polyester Nomex Needle Felt Filter Bag For High Temperature Smoke
Description of nomex filter bag:
Nomex filter bag is widely applied in Asphalt mixing plant for high
temperature smoke filtration .Nomex filter bag ,high temperature
resistant Nomex filter bag ,water repellent treatment .Nomex filter
bag 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 of nomex filter bag
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 fibers; 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
Nomex filter bag ,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. Nomex filter bag
,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) 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

Applications of nomex filter bag:
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.
