Product description

1. Physical intercept filtering and make the filtration more thoroughly, 99% efficiency @0.5um
2. Elastic sealing, repeating using, can be washed by thousand times and the resistance will not add.
3. Elastic PU sealing, instead of Non-degradable plastics, environment-friendly products
4. High efficiency and lower resistance design, more dust capacity, longer lifetime, good performance.
5. G4- H10 efficiency
6. Our professional engineer can design the filters and choose the suitable material according to customer’s requirement. Such as air flow, installation size, efficiency, resistance and so on.

1. Filter durability test per ASTM F494
2. Air pressure loss per: ASTM F-588
3. ASTM F1977-04: Determining Initial, fractional, filtration efficiency of vacuum cleaner filter test standard.
4. ANSI/ASHARE Standard 52.2-2007: Method of Test General Ventilation Air-Cleaning Devices for Removal Efficiency by particle size.
