Can P84 Filter Bags Withstand High Temperature and High Corrosion Environments?
Are you facing the challenges of high temperature and high corrosion in waste incineration plants, coal-fired boilers, chemical plants, or metallurgical industries? P84 filter bags can withstand high temperatures of 240°C for a long time (260°C in an instant) and have excellent acid resistance, easily dealing with corrosive gases such as HCl, Cl₂, SO₂, etc. In addition, the P84 material itself is non-flammable, flame-retardant, safe and reliable. Whether it is chlorine-containing gas released by plastic incineration, sulfide produced by coal combustion, or extreme working conditions in chemical metallurgy, P84 filter bags can operate stably, helping you filter efficiently and reduce maintenance costs!
Cost-Effective P84 Filter Bags
