Air Permeability Tester

Air Permeability Tester


Air Permeability Tester















The air permeability tester is used to measure the air permeability of testile materials. By subjecting the material to controlled airflow, the tester can provide quantitative data on its permeability.

Working Principle

The test sample is placed in a channel with a fixed cross-sectional area, and the specific air flow will generate a certain pressure difference between the upper and lower sides of the test sample.

The test software can automatically calculate the air flow through the fabric according to the differential pressure cross-sectional area, so as to calculate the air permeability of the fabric.
