This Air Permeability Tester for Textiles adheres to multiple international standards, ensuring compatibility with various air permeability testing requirements. It applies to standards such as GB/T 5453, ISO 9237, ISO 9073:2015, JIS L1096 Item 8.26 Method C, BS 3424-16, BS 6F 100 3.1, NWSP 070.1.RO(15), and GB/T 24218.15, making it ideal for global textile manufacturers and research institutions.
The air permeability method involves directing air through the fabric sample, creating a pressure difference between the front and back surfaces. The amount of air that passes through the fabric under a specific pressure difference is measured, providing a precise air permeability value. The method measured on this machine allows for accurate air permeability calculation.
Description
Features of Air Permeability Tester
Tests are easy and fast.
The Air Permeability Tester is user-friendly, allowing you to choose the test standards and measurement units directly from the operation screen. The instrument automatically detects the various ranges of the test fixture head, enabling you to initiate the permeability test and receive results instantly.
Self-designed calibration system ensures accurate testing at all times.
The calibration system has undergone third-party testing, confirming its reliability and authority, which allows users to conveniently calibrate the instrument whenever needed.
More reliable test results
Our innovative test model features maintenance-free range conversion components that eliminate loss, providing high repeatability and reliability in air permeability test results. Additionally, the use of high-quality core components, including pressure sensors from well-known brands, further enhances the accuracy of these results. Canada Goose (Canada headquarters) and the world’s No. 1
electric car brand (USA) uses the instrument for testing automotive interiors.
Smart instrument
You can connect the Air Permeability Tester with the SmarTexLab App installed in smartphones through Wi-Fi. This connection enables you to set parameters, monitor the test status, receive equipment warning reminders, and share air permeability test results with the quality control department or brand buyers. This function also makes the air permeability test for fabric more efficient and transparent.
Application of Air Permeability Tester
The Air Permeability Tester is essential for assessing the resistance of various textiles to air passage, including woven, knitted, non-woven fabrics, and medical masks. The textile sample is securely clamped to resist constant air pressure during the air permeability test.
The automatic holder simplifies the process of loading the specimen into the test area, making it quick and convenient. Then, simply press down on the holder to initiate testing. Next, the machine’s vacuum pump efficiently draws air through the automatic test head, which features a circular opening, ensuring the test pressure remains consistent. Within seconds, the display will show the air permeability units of the tested specimen or notify you if a nozzle replacement is required. After completing the process, just release the holder and turn off the vacuum pump.
This tester provides precise results for understanding what air permeability is and measuring it across various textiles for quality control and performance evaluation.

Testing principle of fabric permeability
This refers to the vertical flow rate of air per unit area of a fabric at a specified differential pressure, which is the pressure difference between the two sides of the fabric. The measurement is expressed in ‘mm/s’. When a pressure difference exists across the fabric, its ability to allow air to pass through is referred to as air permeability.
Difference between moisture (vapor) permeability test and air permeability test
Vapour permeability refers to the permeability of gases through polymer materials such as films, coatings and fabrics. Vapour permeability refers to the ability of water vapour to pass through a fabric, also known in the industry as ‘moisture permeability’. Only air permeability and vapour permeability are both satisfied in order to obtain a comfortable body feeling. For measuring fabric vapor permeability, use this Auto Water Vapour Permeability Tester TF165B.
Fabric air permeability refers to the performance of air passing through the fabric when there is a pressure difference between the two sides of the fabric.
