N900 Air Permeability Analyzer to test the air permeability of many textile, including technical fabric, non-woven and breathable textile products. 1. - Product Introduction N900 Air permeability analyzer, a blend ofmechanism, électron and software, is highprecision experiment-usage testing instrument developed by GB/T5453-1997 Textile--Détermination of the permeability of fabrics of air. Itis applied to test the air permeability of many textile, including technical fabric, non-woven and breathable textile products. Key components: imported pressure sensor, turbofan, air cylinder, motor 2. - Working Principle Air permeability refers to the performance of air pass through the fabric. Indicate it by the rate of airflow vertically penetrating the test sample in a certain test area, pressure drop and time. Keeping a pressure différence, test the airflow vertically penetrating the test area of sample in a certain period of time, so as to calculate the air transmission rate. The airflow rate can be calculated directly, or calculated by testing pressure différences between two sides of flow pore. 3. - Standard GB/T 5453-1997. ISO 9237-1995. GOST ISO 9237-2013.
