About This Product
Air permeability is the rate at which air passes through a fabric under a set pressure difference. It matters for clothing comfort, filtration and similar uses, and is a routine test in textile labs. The fabric is clamped over a known area, air is drawn through it, and the airflow and the pressure drop between the two faces are recorded. Students use the results to compare fabrics of different weave, thickness and finish.
Frequently Asked Questions
Q1. How is the fabric specimen held in the Air Permeability Tester?
It is held between two round grips lined with rubber gasket, which prevents air leaking through the edges. A hand-operated screw mechanism clamps the grips.
Q2. How are vacuum pressure and airflow measured?
Vacuum pressure is read in mm of water on a digital manometer or manometer tube, and airflow is measured by rotameters fitted to the instrument.
Q3. Is a vacuum pump included?
Yes. The vacuum needed to draw air through the specimens is created by the vacuum pump supplied with the instrument.
