Questoair permeability tester is suitable of determining the resistance to the passage of air of woven, knitted and nonwoven, and most of the textile materials.
Features of Air Permeability Tester:
The Textile Air Permeability Tester accurately and swiftly determines the resistance of fabrics (woven, knitted and nonwoven textile) to the passage of air (air flow) under constant pre-set air pressure while firmly clamped in the test rig of selected test head/area.
The air permeability of the fabric is calculated automatically within a short time.

Applications of Air Permeability Tester:
Questoair permeability tester is to measure the air permeability of textiles, clothing, non-woven fabrics and other materials; The fabric is pressed on the selected test head, the instrument generates continuous air flow through the sample, and a certain pressure difference is generated on both sides of the sample. In a very short time, the system automatically calculates the air permeability of the sample.
