The GLOBE Air Permeability Tester for textiles consists of an arrangement to hold the test specimen between two flat faces so as to expose a known area to the flow of air through it, a vacuum system to draw air through the exposed area of the test specimen, arrangement to measure the volume of air flowing through the test specimen, and arrangement to measure the pressure drop between the two faces of the test specimen as a result of flow of air.

 

The test specimen is held between two annular ring shaped grips. The grips are lined with rubber gaskets to reduce flow of air through the edges. The two grips can be brought in contact with each other with the help of a hand operated screw arrangement. The test area can be altered by placing adapter discs of different openings in the grips.
