Branca Air permeability 37SC measures air permeability of textile materials such as clothing and industrial fabrics, technical, downproof, nonwovens, filters, felts, tents, foam materials and other types.
BAP 37SC has innovative technology, eye-catching design; it provides excellent performances for air permeability tests on a huge variety of samples in the textile industry for laboratory tests, QC textile processing and production checks.
The instrument complies with the UNI EN ISO 9237:97 standard that considers air permeability of a fabric such as the rate at which an air volume passes perpendicularly to a sample with specific test area and pressure drop.
The structure of the Air permeability 37SC is a floor standing unit with wheels to move it easily within the work spaces.
Air permeability allows you to test multiple sample points acquiring permeability values quickly and listing a final report.
Through the permeability tests on multiple points of the material, uniformity is determined and therefore the sample quality.
Following the setting of the test parameters, the operator starts the tests through the HMI Touch Screen panel by checking the pressure drop regulation and saving the results at the end.
Pressure drop control is critical and is monitored if within the acceptable limits, otherwise the test will be interrupted.
The vacuum is generated by a BAP 37SC self-cooled suction unit mounted inside the apparel.
Consider a sound pressure level lower than 40 dB.
Through the QUICK CHECK test function the operator gets the results of air permeability quickly after a few seconds, particularly on low-permeable samples.
Air permeability 37SC is supplied with calibration template for calibration check and test area reduction flanges of 50, 20, 10, 5, 2 cm2.
The sample is tightened between the flanges with upper and lower gasket of the test area.
On request, the side locking ring is provided, excluding air leaks laterally and without distorting the test sample.The sample blocking system can be manual by means of fixing knob or electromechanical type commanded with a switch on control panel.
The regulation of pressure drop can be MANUAL or AUTOMATIC type
Air permeability 37SC is designed to support the tablecloths of the material to slide on the test area to verify its uniformity.
Test area reduction flanges are adopted together with the instrument and used in relation to the individual features of the samples to be tested; on request the test area of 38 cm2 is commonly employed in test performances at a pressure drop of 125 Pa according to the Standard ASTM D-737.E.g.: Test with calibration check template;
