  Air Filter Paper Specification

  The technical index of Air Filter Paper can be divided into two aspects, one is filtration characteristics of Air Filter Papers, on the other hand, physical characteristics. Filtration characteristics include air permeability, gas resistance, maximum aperture, and average aperture. Physical characteristics include quantitative, thickness, stiffness, corrugated depth, bursting resistance, resin content.

  Quantitative: Refers to the quality of Air Filter Paper per square meter, unit: $literal.

  Thickness: Refers to the thickness of Air Filter Paper, excluding corrugated depth. Unit: MM.

  Gas Resistance: The resistance of Air Filter Paper to air flow. Using 100CM2 Air Filter Paper in one minutes through 85 liters of air pressure drop value to represent. The unit is mbar. or water column height (mm).

  Corrugated Depth: In order to strengthen the longitudinal stiffness of Air Filter Paper and suppress the depth of the groove, the unit is: MM. In general, the value is 0.2mm.

  Air permeability: In a certain area, under certain pressure (mm water column), per unit of time through the amount of Air Filter Paper. Units are: L/m2·s.

  Nominal filtration accuracy: refers to the resistance of a Air Filter Paper to a certain size of particles, can be blocked or filtered out of the small ball size of 50%. Unit: μm.

  Maximum aperture: The void size calculated by the pressure of the first bubble in the filter sample when it is tested. Unit: μm.

  Average aperture: The aperture calculated by pressure during "dense" bubbling is called the mean aperture. Units are: μm.

  Resin content: Resin as a percentage of the weight of Air Filter Paper. Generally $number

  Stiffness: Air Filter Paper resistant to deformation. Unit: MG.

  Break-resistant: Air Filter Paper unit area can withstand the maximum pressure. Unit: kpa.
