Filter bag selection guide

What filter bags are selected for different industries?
INDRO filtration introduces filter bag selection guide which can show you how to select filter bag materials as followings:

Filter bag materials	Filter material Performance and Adaptive Condition	Common applications and working condition
Polypropylene(PP) filter bags	Suitable for continuous temperature less than 90℃, instantaneous maximum temperature less than 100℃ working conditions, oxidation resistance is general, PH value range: 1 - 14, excellent hydrolysis resistance	It is suitable for dust collection in food, flour, sugar, fertilizer plant, electroplating, pesticide and other conditions.
Acrylic copolymer(AC) filter bags	Suitable for continuous working temperature less than 110℃, instantaneous less than 115℃ working conditions, oxidation resistance is general, PH value range: 6 - 13, relative humidity < 5%.	Dust collection for working conditions such as detergent, pulverized coal and so on
Polyester(PE) filter bags	It is suitable for the condition of continuous temperature less than 130℃ and no more than 150℃. It has good antioxidant capacity, acid alkali resistance and pH range: 4 to 12, relative humidity < 4%, and the life expectancy is affected by the water content of flue gas at high temperature.	It is applied to mine, limestone powder, cement raw material, mill and packaging, iron making, continuous casting, sintering, electric furnace dust removal, alumina transportation, electrolytic aluminum flue gas, non-ferrous metal smelting gas, and dust collection in wood processing, grain processing and pharmaceutical industries.
Polyphenylene Sulfide(PPS) filter bags	It is suitable for working conditions with a continuous temperature less than 160℃ and no more than 200℃ instantaneously. Antioxidant capacity is not good, has excellent acid and alkali resistance, pH range: 1 - 14, relative humidity >30%	Used for dust collection of low-oxygen flue gas in coal-fired boilers, waste incineration, metal smelting, chemical industry, etc.
Aramid(Nomex) filter bags	It is suitable for the condition of continuous temperature less than 204℃ and no more than 240℃ at the moment. The antioxidant capacity is general, pH range: 5 - 9, relative humidity <10%. At high temperature, its performance is affected by water content.	Dust collection suitable for asphalt mixing, non-ferrous metal smelting, ceramic, glass, cement industry kiln head (grate cooler), steel plant blast furnace gas and other working conditions
Polyimide(PI/P84) filter bags	Suitable for continuous temperature less than 220℃, instantaneous no more than 260℃ working conditions, oxidation resistance is general, PH value range: 3 - 13, relative humidity < 25%	It is used for collecting gas from chemical industry, metal smelting, garbage incineration, cement kiln tail and coal-burning boiler.
Polytetrafluoroethylene(PTFE) filter bags	It is suitable for the condition of continuous temperature less than 250℃ and no more than 280℃ at the moment. It has excellent resistance to various chemical corrosion properties. The pH range is 1 - 14 and relative humidity >30%. The filter material has excellent cleaning performance.	It is used for high temperature flue gas dust collection in chemical industry, coal-fired boiler, garbage incineration and non-ferrous metal smelting.
Fiberglass filter bags	Suitable for continuous working temperature less than 260℃, instantaneous less than 280℃,working conditions, good oxidation resistance, PH value range: 4-9, relative humidity 55%	High temperature flue gas collection for cement, coal fired boilers, waste incineration, steelmaking electric furnaces, blast furnace gas and ferroalloy furnace.
