Air Permeability Tester
Air Permeability Tester of textile fabrics complies with ASTM D737, ISO 9237/7231, BS 5636, etc. It is used to test the resistance of the flow of air through fabrics. There is different air permeability test method to do air permeability testing for textiles, we can offer all the test methods and competitive price.

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

The Air Permeability Tester accurately and swiftly determines the resistance of fabrics (woven, knitted and nonwoven textile) to the passage of air (air flow) under constant pre-set air pressure while firmly clamped in the test rig of selected test head/area. The air permeability of the fabric is calculated automatically within a short time.
