Air Permeability Tester KES - F8
The Air Permeability Tester measures the air permeability characteristics of a wide range of materials, from highly breathable gauze to waterproof fabrics with low air permeability. It is suitable for evaluating ventilation resistance in textiles, nonwovens, hygiene materials, and other porous samples.
The tester features a simple sample-clamping mechanism and a digital display for convenient operation and clear readings. Its pressure measurement resolution is specified as 2 Pa. Test results are expressed as ventilation resistance, R (kPa·s/m), with lower values indicating better breathability and air permeability.
Application
(1) Gauze, cotton, fibers, and other textile materials.
(2) Long stockings, socks, underwear, and hosiery fabrics.
(3) Waterproof and moisture-permeable fabrics.
(4) Nonwoven materials and personal-care or hygiene products.
(5) Tissue paper and other porous materials.
(6) Building materials and other samples requiring air-permeability evaluation.
Standards
ISO 9237:1995 — Textiles — Determination of the permeability of fabrics to air
ASTM D737-18(2023) — Standard Test Method for Air Permeability of Textile Fabrics
