ECOGRACE Dust Collection Filter Bag , Fabric Bag Filter Cloth
High temperatures fume / smoke Filter
The most effective use of Nomex filter bag, aramid filter bag is in high efficiency filtration systems where effluent temperature are above 250° F or in systems with surges over 250° F. In hot gas filtration systems, Nomex filter bag require less filter area, for equal gas volume and efficiencies, than fiber glass.
Nomex filter bag:
1. Temperature (°C): Continue: 204, Instant: 240
2. Features : anti-acid,anti-alkali,high filtration blow speed,low pressure drop,anti-break,and anti-abrasion,but it easily be hydrolyzed in the condition of high temperature
3. Application : pitch mix gas,blast furnace gas in steel factory, gas, tail gas of white char,kiln applications,electric cooker high temperature gas,etc.
PPS Ryton filter bag:
1. Temperature (°C): Continue: 190, Instant: 210
2. Features:the best filter medium for anti-acid,anti-alkali,hydrolysis resistant,but it is not good at anti-oxidant
3. Application:waste incinerator,electric station boiler,industry boiler and so on.
P84 filter bag ( Polyimide ) :
1. Temperature (°C): Continue: 260, Instant: 300
2. Features:good chemistry resistance,good air permeability,high filtration efficiency.
3. Application:cement kiln,waste incinerator,etc
Fiberglass filter bag:
1.Temperature (°C): Continue: 240, Instant: 260
2.Features:low price compared with other high temperature fibers,and stable size,low
shrinkage rate,high intensity
3.Application:chemistry,steel factory,metallurgy,cement,etc.
Fiberglass combined tailer produced filter bag:
1.Temperature (°C): Continue: 260, Instant: 280
2.Features:heavy loads,long life time, reasonable price, strong function etc.
3.Application:polluted air and dust in Iron & Steel factory, Melting factory, Cement factory,Petrol chemistry ,etc.
PTFE filter bag :
1. Temperature (°C): Continue: 250, Instant: 300
2. Features: strong stability, wear resistance, chemical stability, temperature resistance is particularly prominent
3. Application:used in steel, power, waste incineration flue gas filtration and other harsh environments.
Technical Specifications for Nomex Filter :
Polyester filter bag:
1.Temperature (°C): Continue: 130, Instant: 150
2.Features:excellent anti-anrasion/High quality and economical/Can be customized.
3.Application : steel works, chemical plant, building, metallurgy, power plant, petroleum
refining, pharmaceutical, dye industry, food processing, etc.
PP (Polypropyline) filter bag:
1.Temperature (°C): Continue: 90, Instant: 120
2.Features:Excellent resistant to hydrolysis, acids and alkalies.Lower fiber release, Lower
density,High mechanical characteristics
3.Application : alvanic industry and Chemical industry,Prefiltering solvents
Anti-static filter bag:
1. Chemical dust and coal dust is often explosive or cause fire, when the concentration reach its explosion limit and meet the static. therefore the needle punched felt, which is used to make bags containing these dust must be antistatic.
2. Features:Excellent anti-static performance/High quality and economical/Can be customized.
3. Application : chemical industry, metallurgy, food pharmaceuticals, construction industry.
4. Type: blend type/line type/matrix type
Homopolymer Acrylic filter bag:
1. Temperature (°C): Continue: 140, Instant: 160
2. Features:Excellent hydrolysis stability/.glabrous surface, easy for separate/High filtration efficiency.
3. Application : waste incinerators, asphalt, dance spray dryer, coal mill and power plant fume gas collection.
