Overview​
The AIRFLOW-4000 measures the air permeability of fabrics, membranes, and composites (ISO 9237, ASTM D737, GB/T 5453). Used in sportswear, medical textiles, and industrial filtration, it ensures optimal breathability for comfort and performance.

​Core Features​

1. ​Adjustable Testing Parameters: Configurable pressure differentials (10–100 Pa) and sample sizes (up to 20 cm²).
2. ​Precision Sensors: Measures airflow rate (L/m²/s) and pressure drop (±1% accuracy) in real time.
3. ​Environmental Control: Heated chambers (5–50°C) and humidity (10–95% RH) simulate operational environments.
4. ​Data Analytics: Software generates permeability curves, pore size distribution, and compliance reports.

​Applications​

• ​Sportswear: Optimize moisture-wicking fabrics for athletic apparel.
• ​Medical Textiles: Test surgical masks and gowns for breathability.
• ​Industrial: Certify geotextiles and filtration membranes.

​Compliance​
ISO 9237, ASTM D737, EN 13685.

​Optional Add-Ons​

• Multi-station fixtures for parallel testing.
• High-speed data acquisition (1 kHz sampling).
• Customizable sample clamps for irregular geometries.

​Conclusion​
The AIRFLOW-4000 delivers critical insights into fabric breathability, enabling manufacturers to balance comfort and functionality.
