Air permeability tester is used for air permeability testing of all flat materials and foam panels. The test range includes paper, airbags, and non-woven fabrics. During the test, the fabric was clamped by the test head and pressed under the clamp arm. When the clamp arm was pressed, the air pump was automatically started, and the instrument was tested according to the set parameters. Specific information as follows:

(1)Standards：

BS 5636 ，JIS L1096-A，DIN 53887，ASTM D737，ASTM D3574，EN ISO 9237，GB/T 5453，EDANA 140.2，TAPPI T251，EDANA 140.1，ASTM D737，AFNOR G07-111，ISO 7231

(2)Automatic Air Permeability Tester Scope of application:

Measuring the permeability of textiles, garments, non-woven fabrics, etc.; the fabric is pressed on the selected test head, the instrument produces a continuous airflow through the specimen, and a certain pressure difference is generated on both sides of the specimen. In a very short time, the system automatically calculates the air permeability of the sample.
