AIR PERMEABILITY 37S Branca Idealair is an air permeability tester able to determine the exact air permeability of fabrics and other materials

Air permeability 37S is an air permeability tester suitable for all textile fabrics, included garments and industrial fabrics, for technical use, woven and non-woven fabrics, air bag fabrics, blankets, napped fabrics, knitted fabrics, layered fabrics and pile fabrics, filtration materials, felts, paper and other materials permeable to the air.

The Air permeability tester 37S determines the exact rate of air flow with which a fixed air volume (10 or 100 Lt) passes perpendicularly across a specimen just after having set paramenters according to the specific requirements by the Standards as the test area (cm2) and the pressure drop (Pa) and endly the time period (s) in conformity with the Standard UNI EN ISO 9237:07.

The HMI 5" monochromatic touch screen allows the overall management by the operator able to monitor test running, to store data on memory and of course to set parameters according to the reference Standard and material to be checked:

Test area (cm²): 2, 5, 10, 20, 38, 50, 100;
Pressure drop (Pa): 0..1000 (0..100 mm WC)
0..2500

Pressure drop fine regulation (e.g. 200 Pa) can be done manually by the operator with knobs or automatically with a close-control adjustment system on request

Test results are expressed in the following measure units as shown below:
  • Lt/m²/s (mm/s)
  • m/s
  • Lt/min
  • Lt/h
  • CFM
  • dm3/s
  • cm3/cm2/s
