The air permeability tester is a high-precision testing instrument designed to evaluate the breathability of PPE materials, textile fabrics, non-woven fabrics, woven fabrics, and industrial filter media. It plays a critical role in quality control, product development, and laboratory research across multiple industries including PPE, textiles, automotive interiors, and filtration systems.
Modern instruments such as the GT-C27 Air Permeability Tester are developed with advanced sensor systems, automated control logic, and multi-standard compatibility to ensure reliable and repeatable results. Complying with global standards such as ISO 9237, ASTM D737, DIN 53887, and GB/T 5453, it guarantees internationally recognized testing performance.
With high automation, accurate pressure sensing, and flexible unit conversion systems, air permeability testing equipment significantly improves testing efficiency while reducing human error. It is widely used in PPE manufacturing, textile engineering, non-woven product development, and industrial filtration quality inspection.
