Description
What is the Air Permeability Test?
Auto Air Permeability Tester, or air permeability tester for fabric is used to determine the air permeability of fabric automatically. With its wide measuring range, it is suitable for all kinds of knitted, woven, non-woven, coated fabrics, paper, film, leather, etc. Besides, air permeability test equipment can also be used to measure the differential pressure of airflow from two sides of breathability-related products like face masks.
Put a test sample on the clamping head; and then set the test parameters on the Android software on the Samsung tablet. By pressing down the upper clamping arm the system automatically starts, the system automatically adjusts the machine, and then shifts nozzles if required; after a few seconds the test results are then displayed and the excel report is generated, and the test results are displayed on the Samsung pad.

The Air Permeability Definition of Fabric
What is the permeability of air? Fabric permeability refers to the air permeability of fabric in the presence of pressure difference on both sides of the fabric, that is, the volume of air flowing through the fabric per unit and area per unit time under the specified pressure difference between the two sides of the fabric. Because pressure difference is a necessary condition for air flow, air flow in the fabric can only be produced by maintaining a certain pressure difference on both sides of the tested fabric.
The Importance of Fabric Permeability
Fabric permeability is an important factor affecting fabric comfort and service performance. For example, sportswear, cagoule and warm wear have higher requirements for fabric permeability, and some industrial textiles such as parachute and filter cloth have special requirements for fabric permeability. Only the fabric that conforming to the requirements of air permeability can meet the different needs of our life and production.
Testing Principle for Air Permeability The sample is fixed to the test zone through the handle. By pressing the test head to begin the test, a strong aspirator pump begins to draw air through an interchangeable test head at a circular opening. After the preset test pressure is automatically started and maintained for a few seconds, the air permeability of the tested sample is displayed in a preset unit of measurement. Press the test head again for one second, the sample is released and the aspirator pump is closed.
Test standard for Air Permeability of Fabrics
The measurement of air permeability is based on the fixed pressure difference as the benchmark for the test. Because the pressure difference stipulated in the national test standards is not consistent, current the common test standards are the: ASTM D737, ISO 9237, GBT 5453, and JIS L1096. The test requirements for each method, test results and conversion between common air permeability units are shown below.
The Test Methods for Each Standard are Compared as Follows

The Test Results of air permeability rating for the Different Standards are as Follows
[table id=918 /]
Common Conversion Table of Air Permeability Unit
[table id=919 /]
There are many standards for testing the air permeability of fabrics, and there are slight differences between the standards according to the size of the test area and the value of the differential pressure air permeability tester. The air permeability meter should carry out the test strictly in accordance with the regulations.
Conventional Operation Flow
- Prepare the samples as required and cut them into the required size.
- Check the calibration instrument.
- Turn on the power switch, enter the control interface to set the test parameters, and then enter the test interface.
- Place the specimen in the test area and clamp it on the test table. The test position should avoid from the edges and creases, and the specimen should be kept flat before clamping.
- Start the instrument and begin test automatically. The suction fan start and the air through the sample, when the pressure difference approaches the specified value the instrument will records the air flow automatically.
- Complete the test, press the test head, release the sample, and test the sample in different positions.
- Repeat the above operation to test a set of samples, after the test, query the results and display the test average.

您好,我们的业务员会稍后联系您。
Evan Samson –
It seems to work well so far. The only reason I didn’t give it a 5 star rating is because I haven’t really had it long and am not sure yet how it will hold up throughout time. But like I said, it’s been great so far.
