What are the features of Fully Automatic Digital Air Permeability Tester?

The Fully Automatic Digital Air Permeability Tester is suitable for a wide variety of fabrics including wovens, non-wovens, airbag fabrics, blankets, pile fabrics, knitted fabrics, multi-layer fabrics and lint fabrics that can be used for competitive, large area , coated, resin-treated or any other treated. The instrument can also test airflow through thick, elastic porous objects such as polyurethane foam. With a compact design, it is easy to install and test large area samples. The pressure system automatically detects the range of air pressure and detects and calibrates the mounted test head. The test results can be displayed on the LED display, and can also be input into the computer through the software (optional).

The air permeability test manufactured by QINSUN instruments is based on a fixed differential pressure as the benchmark for air permeability testing. The pressure difference stipulated by the test standards of various countries is not consistent. For example, American ANSI/ASTM, K773, FS191/5450 and Japan's JISL1096 stipulate that it is 127.4Pa (13mm water column); French NFG07-111 stipulates that it is 196Pa (20mm water column); German DIN53387 stipulates clothing The fabric is 100Pa (10mm water column), the parachute fabric is 160PA (16mm water column), the filter fabric and industrial fabric is 200Pa (20mm water column); the British BS5636 stipulates that it is 98Pa (about 10mm water column), etc.
