RAMP-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, Air Permeability Tester To test the air permeability of various woven fabrics, knitted fabrics, non-woven fabrics, Protective Clothing, industrial filter materials etc.
Application Fabric, including garments and industrial fabrics, technical fabrics, woven, nonwoven, paper, rubbers, filters, felts and
other materials permeable to the air.
