Air Permeability Tester for Plastic

The Air Permeability Tester for plastic determines the air leakage of plastic films. This is a digital model. thus, ensures repeatable and consistent performance. The flexible design allows inserting sample at the front. This is with a small opening of 5 mm as well as a 45 mm lead.  It features two safety activation switches for clamping. So that the operators are using both hands to ensure optimum safety.

Test procedure of Air Permeability Tester

The test process starts by connecting compressed air supply to instrument and turn on air safety relief valve on rear of machine. The test sample should be prepared 300mm x 150mm using a knife. Then, the test pressure is set by adjusting test pressure regulator on rear of machine and verify on front pressure gauge. After that, the prepared sample is placed between the clamps, and hold down the two activation switches simultaneously. The upper clamp will lower and hold the sample in place. The lower chamber will pressurise to the pre-set pressure. Finally, the reading from the digital display (litres / min) can be obtained. Press Sample Release button, to turn off the test air supply and the sample is released for the next sample to be inserted.

Results using the Air Permeability Tester

The litres/min obtained at a pre-set pressure will enable the user to quantify the air leak of perforated plastic film.
