Our fabric air permeability testing apparatus comprises essential components: a central unit, a pump, a pressure gauge, a flow meter, and a sample holder. The central unit serves as the command center, housing a microcomputer that orchestrates the tester's functions. Operating in harmony, the pump generates the necessary pressure differential, while the pressure gauge meticulously quantifies this pressure variation. Simultaneously, the flow meter diligently quantifies the volume of air traversing the fabric sample, and the sample holder securely cradles the fabric specimen in place. This comprehensive ensemble of components ensures precise and efficient assessment of fabric air permeability, making it a reliable tool for various applications requiring meticulous airflow analysis.
