Air Permeability Tester - TNG1051

The TNG1051 Air Permeability Tester is designed to determine the air permeability of various textile materials by measuring the air flow rate through a sample under controlled pressure. The instrument operates by applying a specified air pressure to the sample and measuring the resulting air velocity. This allows for the assessment of how easily air passes through the material, which is critical for applications requiring breathability or air resistance. The tester supports multiple international standards including BS 3424-16, BS 6F, ISO 9073, ISO 9237, and JIS L1096. It is suitable for testing materials such as technical textiles, non-woven fabrics, sponges, paper, and other breathable materials. The TNG1051 features an automatic test mode and can accommodate test heads of different sizes, including standard 20 cm² and optional sizes of 5 cm², 25 cm², 38 cm², 50 cm², and 100 cm². The test pressure range is 10 to 2,500 Pa, and the air velocity can be measured from 0.6 to 10,000 mm/s. The machine is powered by 220V/110V at 50/60Hz. The testing accuracy is within +/-2%, ensuring reliable results. The instrument is equipped with a self-designed calibration system that has been third-party tested for reliability. The TNG1051 provides precise and consistent measurements, making it a valuable tool for quality control and performance evaluation in textile manufacturing.

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.

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.

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.
• 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.

Frazier air permeability test method (ASTM D737 testing)of textiles 1.Air permeability definition What is the permeability of air? The air permeability is the volume of air passing a fabric under pressure. There are two types of air permeability tester for textiles, Frazier air permeability tester and Shirley air permeability tester. In ASTM D737 test method, we take Frazier differential pressure air permeability tester as an example. 2.Test Objectives: To determine the air permeability of textile fabrics by calculating the air permeability value. 3.Test Materials: Woven, knitted and non-woven textile materials. eg. cotton. 4.Air Permeability Test Procedure: 4.1 The specimens must be adjusted to the standard atmosphere with 21 +/- 1°C (70 +/- 2°F) and 65 +/- 2 % relative humidity unless there is otherwise specification of contract order.
