Air Permeability Tester

The Air Permeability Tester tests the resistance of the flow of air through fabrics. This fully automatic instrument can quickly and accurately assess air permeability of various materials. Such as woven fabrics, knitted fabrics, non-woven fabrics, industrial filter materials. As well as paper and foam products.

Air Permeability Tester of textile fabrics complies with ASTM D737, ISO 9237/7231, BS 5636, etc.

Air Permeability Tester is useful for all textile materials and medical masks. This is suitable to conduct the Breathing resistance performance of medical masks. Thus, complying with the medical masks testing standars EN 14683.

The test starts by loading the specimen to the test area. The automatic holder makes it easy to do so. The, pressing the holder down starts the test. The machine comes with a vacuum pump to draw air through an automatic interchangeable test head with a circular opening. The instrument automatically maintains the pressure.  And a few seconds the air permeability of the test specimen occurs. The digital touch panel displays the result. This is in the unit of measure as chosen before. Or the nozzle showing next test required will be replaced on the display. The test ends by releasing the holder. The Vacuum pump shuts off as well.

About Air Permeability Test 

Air permeability is the degree of airflow exceeded via a given area of fabric. This parameter affects the thermal comfort properties of the fabric to a huge extent. It is usually accepted that the air permeability of the fabric relies upon its air porosity, which in turn affects its openness. With more porosity, more permeable material is obtained.
