N900 Air Permeability Analyser
The N900 Air Permeability Analyser is a high-precision instrument designed for experimental use, combining advanced mechanical, electronic, and software components. It is developed in accordance with the GB/T 5453-1997 standard for textile air permeability testing.
Applications
The N900 is ideal for testing the air permeability of a wide range of textiles, including technical fabrics, non-woven materials, and breathable textile products.
Key Components
- Imported pressure sensor
- Turbofan
- Air cylinder
- Motor
Working Principle
Air permeability measures how well air passes through a fabric, indicated by the rate of airflow vertically penetrating the test sample within a specified test area, pressure drop, and time. The test involves maintaining a pressure difference and measuring the airflow through the sample over a certain period to calculate the air transmission rate. This rate can be determined directly or by assessing the pressure differences across the flow pore.
Standards
The N900 Air Permeability Analyser complies with the following standards:
- ISO 4638-1984
- ASTM D737-2004(2016)
- GB/T 5453/1997
- ISO 9237-1995
