OUR BROCHURE
The test measures the rate at which air passes through a material. Here’s a detailed explanation of how the test works:
The Test Principle of Air Permeability Test Apparatus
Sample Preparation:
The team will test the material sample. It is firmly mounted in the test apparatus to prevent air from bypassing.
Controlled Airflow:
A pump or blower drives air through the sample.
The team precisely controls and measures the airflow rate and pressure differential.
Pressure Differential (ΔP):
The experiment applies a known and constant pressure difference across the material.
This air permeability test simulates real conditions.
They are the ones the material will face. We measure the pressure differential in pascals (Pa) and inches of water column (inH2O).
Measurement of Airflow Rate:
The volume of air passing through the material per unit of time is measured. This is the core measurement in an air permeability test.
Most cases measure the airflow rate in cubic centimeters per second (cm³/s) or cubic feet per minute (CFM).
Air Permeability Calculation:
To calculate air permeability, divide the airflow rate by the sample area.
This gives an air permeability value, usually in cm³/s/cm² or CFM/ft². It measures the material’s air permeability.
Air Permeability Test Method or Air Permeability Test Procedure
Calibration is performed using 20cm2 upper and lower fixtures, with units selected in mm/s. And you can enter the calibration mode on this Air Permeability Tester operation screen. You can calibrate the air flow and differential pressure.
Please view the air permeability tester operation manual for the detailed calibration steps or contact us.
You should ground the instrument shell reliably. Its grounding resistance should be ≤ 1Ω.
Clean the filtering steel mesh once a month. The mesh is stainless steel. It is best to blow it with high-pressure gas or wash it with water. To wash with water, put it into the instrument after drying. Place the mesh in the designated location.
Take out the lower fixture and see the filtering stencil.
You can use the sealing rubber sheet, supplied as an accessory, to test the airtightness of the device. Contact ChiuVention to replace the rubber sheet when it wears out.

How to ensure accurate Air Permeability Test results for your samples?
Prepare the Sample :
Ensure the sample surface is clean, flat, and free of breakage, so as not to affect the test results. The sample size should be in line with the requirements of the test standards; too large or too small samples may affect the air permeability test results.
Test environment:
The test should be conducted in a constant temperature and humidity environment. Avoid testing in a windy or strong airflow environment, because it will interfere with the air permeability test results.
Equipment Calibration:
Before the air permeability test for fabric, please calibrate the permeability tester to ensure the accuracy of the test results.
Test parameter setting:
According to the characteristics of the material and test standards, correctly set the test parameters, such as pressure, time, etc. Keep the consistency of the test parameters in order to compare the test results of different samples or batches.
Operation specification:
Strictly follow the operation manual or standard procedures for testing in order to reduce errors. Operators should attend a training course, familiarize themselves with the testing process, and take precautions.
Safety Protection:
There should be some safety facilities in the laboratory, such as an emergency stop button fire fire-fighting equipment.
Results Analysis:
Carefully read the test results to eliminate outliers and compare with the standard or data from before. Analyze the variability of the test results and retest if necessary to verify the consistency of the results.
What is a good score on the air permeability test?
In general, Air Permeability Value are usually in the range of 100 to 300 liters/m2/sec. This range ensures adequate breathability and comfort.
It provides a good balance between fabric breathability and protection. These values are effective for everyday applications. Different applications require different air permeability values. Some applications typically require less than 100 L/m2/s. Low air permeability helps block wind and moisture. It enhances the protective properties of the material.
Other applications require higher scores. Air Permeability Values above 300 L/m2/s are common. High Air Permeability is often a characteristic of high-performance materials designed for functionality. They keep the user cool and comfortable.
What parameters does an air permeability tester measure?
An air permeability tester typically measures the following parameters:
Air Permeability is the primary measurement. It shows the amount of air that passes through a material over time. People often express it in units such as cubic centimeters per second per square centimeter (cm³/s/cm²). Or, they use cubic feet per minute per square foot (CFM/ft²).
The pressure differential (ΔP) is the difference in air pressure. It’s between the two sides of the material being tested. The differential is usually kept constant during the test. This standardizes the measurement of air permeability. Common units are pascals (Pa) or inches of water column (inH2O).
Sample Area: The area of the material sample through which the air is passing. This ensures that the air permeability is calculated per unit area. It is generally measured in square centimeters (cm²) or square inches (in²).

What is the difference between air permeability and breathability?
While often used interchangeably, air permeability specifically refers to the rate of airflow through a material under a defined pressure difference. Breathability generally refers to the overall comfort of material in allowing air and moisture vapor to escape, which is a broader concept that may include other factors like moisture-wicking properties and heat dissipation.
Can air permeability be controlled or adjusted in materials?
Yes, textile manufacturers can improve air permeability by adjusting material designs. They can change fiber density, weave patterns, and material thickness. Also, surface treatments can help. Coatings or membranes may also be applied to reduce air permeability.
How do I choose the right level of air permeability for my product?
The ideal level of air permeability depends on the application. For example, sportswear needs high air permeability for breathability. In contrast, windproof jackets, insulation materials, and certain filters require lower permeability.
Can air permeability testing be conducted in different environmental conditions?
Yes, air permeability testing can account for different environments like temperature and humidity. Testing under real-world conditions can affect air permeability test values. So, it’s important for accurate results.
How much does an industrial air permeability tester cost?
Prices for air permeability testers can vary depending on factors such as brand, features, and specifications:
