GUANLIN aramid high temperature filter bag, Nomex needle felt bag for asphalt mixing and hot gas dedusting.
Aramid needle felt filter bags for asphalt plants, hot mix facilities and other continuous high temperature dust collection duties up to 204°C.
Description
Asphalt plants run their baghouses hot and they run them hard. The bag sees 160–190°C gas carrying fine aggregate dust and oily condensate, cycle after cycle, with cleaning pulses that flex the media millions of times over its life. Aramid needle felt is the established answer because it holds strength at temperature and resists the abrasion that comes with the dust load.
Why Choose GUANLIN Aramid High Temperature Filter Bags
- 204°C continuous — matched to asphalt plant gas temperatures.
- High tensile strength — resists pulse flex fatigue.
- Singed and calendered — clean release, stable pressure drop.
- PTFE coating option — improved acid and condensate resistance.
- Precise dimensions — correct fit on the cage, no bypass.
- Proven in asphalt — the standard media for the duty.
