(1) Textile Industry: woven fabrics, knitted fabrics, nonwoven fabrics, coated fabrics, technical textiles

(2) Apparel and Sportswear Industry: breathable clothing, sportswear, protective wear, jackets, functional garments

(3) Medical and Healthcare Industry: surgical masks, medical gowns, medical nonwoven fabrics, filter materials

(4) Filter and Air Treatment Industry: air filters, HEPA filter media, HVAC filters, automotive filter fabrics

(5) Quality Control and Inspection: production consistency testing, material verification, laboratory testing of fabric batches

(6) Research and Development: development of new textile materials with controlled airflow, comparative fabric studies, innovative breathable fabrics

(7) Technical Textile Applications: industrial fabrics, geotextiles, industrial membranes, packaging materials

(8) Educational and Testing Institutes: teaching laboratories, material testing centers, third-party certification testing

The instrument is widely used for product development, quality control, R&D, and laboratory testing.

Standards

The instrument complies with and can be applied to the following standards (including but not limited to):

(1) ASTM D737 – Standard Test Method for Air Permeability of Textile Fabrics Using the Frazier Tester

(2) ISO 9237 – Textiles — Determination of Air Permeability of Fabrics

(3) EDANA WSP 070.1 – European Nonwovens Association Method for Air Permeability Testing

(4) JIS L1096 – Japanese Industrial Standard for Air Permeability Tests of Fabrics

Features

(1) Automatic control mode for stable and repeatable measurements

(2) Suction-type air supply ensuring uniform airflow through the specimen

(3) Digital measurement and display of airflow and test duration

(4) Multiple test stations (up to 12) for efficient batch testing

(5) Interchangeable test heads and orifice sizes to accommodate fabrics with different air permeability

(6) Compliance with international standards (ASTM, ISO, EDANA, JIS) for reliable and comparable results

(7) Supports quality control, material comparison, product development, and research applications

(8) Objective evaluation of fabric breathability, openness, and technical performance
