Airflow Resistance Tester


The textile airflow resistance tester is used to determine the anti-penetration properties of ordinary fabrics and medical protective masks to airflow at a constant flow rate . It is mainly used for the determination of air penetration of textiles ,cotton, and space cotton. The tester is one of the important means to identify the comfort and hygiene of clothing textiles, especially medical textiles.
