Feature
PureMax® dust filter bags are consumables widely used in various industrial dust collection equipment. However, considering the operating costs of factories, in addition to general singed, calendered or flame retardancy treatments, PureMax® dust filter bags can also be specially treated with the function of oil-proof, waterproof, and corrosion-proofing to meet the dust characteristics and operating environment requirements of various industries. This significantly improves the dust filtration efficiency and the product's lifespan, thereby reducing replacement frequency, time, and monetary costs.
Advantage
▪ Versatile Filter Media SelectionDifferent dust characteristics and process requirements,
including Polyamide, Polyester, Polypropylene, Nomex, PTFE (Teflon), GLass fiber, and more.
▪ Wide Range of Particle Filtration
Filter media can be selected according to dust particle size and filtration requirements.
For particle sizes ranging from approximately 30 μm to 0.3 μm.
▪ Multiple Temperature Resistance Grades
Standard heat-resistant filter cartridges generally support operating temperatures ranging from approximately 80°C to 200°C.
Suitable filter media can also be selected according to actual process conditions
