This Air permeability tester is able to test all types of fabrics.
Repeatability and reproducibility of test results improve thanks to the particular attention given to the design of a new frame structured in a duplex volume that separates electronics and precision sensors from suction unit motor that generates a direct thermal heat dissipation.
The tests comply with Standard UNI EN ISO 9237:97, ASTM D-737 and other related norms.
With the mask testing kit to measure "DIFFERENTIAL PRESSURE" done on protective masks the instrument AIR PERMEABILITY BRANCA 37SC is designed in compliance with the reference standardEN 14683:19 and ASTM F2100.
Quick check functionNEW introduced in the operation of this air permeability tester allows the user to measure quickly several points of the sample storing all test results on memory and mapping the fabric.
At the end of each test the operator obtains the test report to analyze the uniform processing of the material, thus improving its quality during production and defining clearly technical features chosen .
After few initial settings, the user runs immediately an automatic test following it up closely on touch screen watching pressure drop fine regulation (Pa), test time (s), and results savings.
FYI: Fine adjustment under pressure drop can be manual or automatic by means of modulation devices arranged on air circuit.
A) Pressure drop is generated from an innovative ultra-silent vacuum motorwith a noise level lower than 40 dB.
B) Thanks to the QUICK CHECK function the operator achieves rapidly test results after just few seconds advisable for low-permeability, e.g. downproof materials;
D) Electro-mechanical clamping with activation switch ideal for ASTM D-737, where flanges always the same tightening force.
Air permeability 37SC is fully-equipped with a calibration check plate for periodical checks of precision sensor reading.
To test nonwoven samples thicker than 1 cm or more, special cover sleeve with desired air passage area (e.g. 20,50,100 cm2) that can be applied on the original flanges.
Air permeability tester 37SC has two side extendible wings to position comfortably the fabric reel.
Reduction flanges to get lower air crossing surfaces to 50, 20, 10, 5, 2 cm2 are arranged together with the air permeability tester and used in correlation to Reference Standard; on request auxiliary test area of 38 cm2 is given for test performances under pressure drop set at 125 Pa according to the norm ASTM D-737.
