Air Flow Tester For Testing Lab

Air Flow Tester - The air flow tester is used for determination of ease with which air passes through the cellular structure of a piece of polyurethane foam at a specified difference in pressure across its two faces. It is defined as the rate of flow of air through a defined area and thickness under a specified pressure difference. The Air Flow Tester for polyurethane foam consists of an arrangement to hold a test specimen in a square opening in a cylindrical chamber 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 specimen, arrangement to measure the rate of flow of air through the test specimen, and arrangement to measure the pressure drop between the two faces of the test specimen as a result of flow of air civil lab equipments manufacturers
