Air Permeability Tester

The “METLOR” Air Permeability Tester for textiles is used for air permeability testing of the fabrics. Digital and analog models are available. This system consists of an arrangement for holding the test specimens between two flat faces so as to expose a known area to the flow of air through it, a vacuum system to draw air through the exposed area of the test specimens. There is an arrangement to measure the volume of air flowing through the test specimen, and arrangement to measure the pressure drop between the faces of the test specimen. The test specimen is held between two round-shaped grips. The grips are lined with the rubber gasket to avoid the leakage of air through the edges. The two grips can be held the test specimens with the help of a hand operated screw mechanism. The vacuum needed to draw the air through the test specimens is created with the vacuum pump supplied with the instrument. The vacuum pressure is measured by the digital manometer (or manometer tube) in terms of mm of water level & airflow is measured by the Rotameters attached with the instrument. The equipment is metallic paint & bright chrome plating finish for corrosion resistant finishing.
