Industrial Dust Collector Nomex Air Filter Bag For Asphalt Plant baghouse
Nomex Anti - Acid Filter Bag
We select Dupont Nomex Filter Fiber to produce the Nomex high temperature needle felt , it is the best filter material for high temperature fume / dust / ash, for steel plant, asphalt mixing, other metal industries .
The characteristics of nomex filter needle felt: High temperature (204~ 240 degree), anti -acid, anti-alkali, high filtration precision, blow speed, low pressure drop, anti -break, anti -abrasion, mostly applied in pitch mix gas, blast furnace gas in steel factory, tail gas of white char, kiln applications, electric cooker high temperature gas.
The normal specification of Nomex Filtration Felt :
400 gsm , 450 gsm , 500 gsm , 550 gsm , 600 gsm ,
Threatment : PTFE coating, PTFE membrane, Water and oil repellemnt treatment .
Although we can tailor produce the size of Nomex Filter Bag for different Model of dust collector , there is normal size as following :
