Air Permeability Tester

DRK461F Air Permeability Tester

Instrument use:

Used for testing the breathability of industrial fabrics, non-woven fabrics, coated fabrics, and other industrial paper (air filter paper, cement bag paper, industrial filter paper), leather, plastics, and chemical products that require controlled breathability.

Standard：

FZ/T 64078-2019 melt blown nonwoven fabric 4.6 air permeability, GB/T 24218.15, GB/T5453, GB/T13764, ISO 9237, EN ISO 7231, AFNOR G07, ASTM D737, BS5636, DIN 53887, EDANA 140.1, JIS L1096, TAPPIT251 and other standards.

Product features：
This model is designed based on the actual large testing volume of various local fiber inspection, quality inspection, commercial inspection, and third-party notary testing institutions. It can be easily tested by simply pressing the gripper, without the need for other operations. The data is automatically saved, which improves the testing efficiency.

The instrument adopts new technology, high configuration, and the whole machine shell is treated with baking paint technology, with beautiful appearance, stable performance, easy operation, and no need for special maintenance in the future, resulting in low maintenance costs. Full screen display and operation.

1. The full screen can be used for separate control testing, or a computer can be used for control testing. The computer can display the dynamic curve of pressure difference and air permeability in real time, which is convenient for controlling product quality and allowing R&D personnel to have a more intuitive understanding of the sample’s air permeability performance;

2. Adopting high-precision imported micro differential pressure sensors, the measurement results are accurate, with good repeatability, and the data comparison error with foreign brands is extremely small, which is significantly better than related products produced by domestic peers;

3. Fully automated measurement is achieved, with the sample placed in the designated position and the instrument automatically finding the appropriate measurement range, adjusting automatically, and measuring accurately.

4. Pneumatic clamping of samples, fully meeting the clamping requirements of various materials;

5. The instrument adopts a self-designed noise reduction device to control the suction fan, solving the problem of high noise caused by large pressure difference in similar products;

6. The instrument is equipped with standard calibration orifice plates, which can quickly complete calibration to ensure the accuracy of data;

7. By using a long arm clamping handle, it is possible to measure larger samples without having to cut them small, greatly improving work efficiency;

8. The special aluminum sample table has a metal baking paint treatment on the entire machine shell, which is durable and has a beautiful and elegant appearance, making it easy to clean;

9. The instrument operation is very simple, with interchangeable Chinese and English interfaces, making it easy for even inexperienced personnel to operate;

10. Testing method: Rapid testing (single test time less than 30 seconds, quickly obtain results);

Stability test (the fan’s exhaust speed increases uniformly, reaches the set pressure difference, and maintains the pressure for a certain period of time to obtain the result, which is very suitable for high-precision testing of fabrics with relatively low breathability).
