Air Flow

These flow charts were generated by conducting flow tests on porous plastic disc randing from 1/8" to 1/2" thick, 20 to 100 microns mean pore size, and 40 to 50% void volume. The void volume of POREX Porous Plastics varies from about 35 to 65%. An increase in void volume will result in a fhigher flow at the same pressure and mean pore size. Back pressure and flow rates are essentially proportional to material thickness.

Because other factors, such as surface characteristics and pore size distribution, can also affect permeability, the flow charts should only be used for general information.
