Factory Wholesale Air Permeability Tester

Air Permeability Tester, widely used to test the resistance of fabrics (woven, knitted and non-woven textile materials) to the passage of air (air flow), the test textile is firmly clamped by a specified rig of selected test head/area to resist the constant air pressure settled before the permeability test.

The specimen is loaded to the test area of the instrument easily by means of an automatic holder. By pressing down the holder to start the test. Air permeability tester equipped with a vacuum pump to draw air through an automatic interchangeable test head with a circular opening. The pre-selected test pressure is automatically maintained, and after a few seconds the air permeability of the test specimen is digitally displayed in the pre-selected unit of measure on the touch panel, or the next test nozzle required to be replaced will be displayed. After the test, the holder is released and the vacuum pump will be shut off.
