Like the bench-top apparel, Air permeability 37S, the upgraded version AIR PERMEABILITY 37SC measures the exact air permeability of all types of permeable fabrics.
Air permeability 37SC has a NEW DESIGN
Repeatability and reproducibility improve thanks to the particular attention given to the design of a new frame structured in a double indoor volume that separates devices that generate a a thermal load by suction unit from those of precision measuring sensors and of airflow control.
The tests has to be carried out by operators inside conditioned areas to be in compliance with Standard ISO 139 as prescribed by reference norms UNI EN ISO 9237 and ASTM D-737 and equivalent ones.
The Quick check function introduced in the logic of the apparel allows the operator to measure quickly multiple points of the specimen/mesh saving directly all results on memory.
At the end of the test the operator will have a full test report to evalute the uniformity of the whole material, thus its production process and finishing.
After the initial test settings, the user runs an air permeability test monitoring events on touch screen by means of command function keys for Pressure drop (Pa), Time (s) and other parameters analyzing test running and results savings.
Fine adjustment on pressure drop can be chosen manual or automatic by means of modulation devices arranged on air circuit.
A) The suction is powered from an innovative ultra-silent vacuum unitwith a noise level lower than 40 dB incorporated inside the tester.
B) Thanks to QUICK CHECK function the operator achieves the air permeability results after few seconds also testing very low permeability samples;
C) Pressure drop control can be both manual or automatic
D) Electro-mechanical clamping system with activation switch ideal for ASTM D-737, where flanges always same clampling force not exceeding 0 ± 5 N.
Air permeability tester 37SC is supplied together with a calibration check plate for periodical checks on machine calibration.
With thicker samples up to 1 cm or more, special cover sleeve with requested area (cm2) can be applied on original test area.
Air permeability tester 37SC is designed to support roll of materials to slide on test area to verify its uniformity.
Test area reduction flanges of 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 used in test performances under pressure drop set at 125 Pa in compliance with Standard ASTM D-737.
