TQD-G1A Air Permeability Tester

TQD-G1A Air Permeability Tester is applicable to the test of air permeability and air resistance of automotive interior decoration materials, such as polyurethane foam, PVC, leather, textiles, nonwovens etc. In addition, it can also be used to test the permeability of separation membrane, sponge, carpet, non-woven fabric, paper and leather. Through measurement, the performance control of materials is realized to meet the needs of practical application of products.

Test Principle

Method A:the air flow is stabilized vertically through the sample at a constant flow. Then, the pressure difference formed on both sides of the sample is measured under this condition, and air flow resistance and other parameters are calculated.

Method B:through adjustment, a constant pressure difference is formed on both sides of the sample, the air flow passing vertically through the given area of the sample in a certain time is measured, and the air permeability and other parameters are calculated.
