Air is suctioned through the material to be measured with a specific pressure. The generated air flow is measured, and the air permeability of the material can thus be determined.
Permeability measurement is used for all air-permeable materials such as textile, nonwoven, paper or composite material. The applications range from simple textiles to highly complex filter materials.
