How Does An Air Permeance Tester Evaluate Membrane Pore Structures?

An air permeance tester evaluates membrane pore structures by measuring the rate at which air flows through a membrane under a specific pressure difference, essentially providing information about the size, distribution, and connectivity of pores within the membrane; a higher air permeance indicates larger or more interconnected pores, allowing for greater air flow through the material, while a lower permeance suggests smaller or less connected pores, restricting air passage.

An air permeance tester evaluates membrane pore structures by measuring the airflow rate through the membrane under controlled pressure. The test determines how easily air passes through, reflecting the size, distribution, and connectivity of pores. Higher permeance indicates larger or more connected pores, while lower values suggest smaller or tighter pore structures. This data helps assess the membrane's filtration efficiency, durability, and suitability for specific applications.
