Air Permeability 37S is a fabric testing apparel able to determine the exact resistance of a determined flow of air through fabrics and other permeable materials.

Designed for all analyses on textiles, including garments and industrial fabrics, for technical use, on woven and non-woven fabrics, airbag, blankets, napped fabrics, knitted fabrics, layered fabrics and pile fabrics, downproof, filters, felts, paper and others fabric types.

The air permeability is defined by air speed of a fixed volume crossing perpendicularly the specimen under examination.

After setting test parameters of test area (cm2), pressure drop (Pa) as requested by the norms it's an easy operation to make the test start.

Front control panel is equipped with a 5" HMI Touch Screen as user interface for the overall management and diagnostic leds.

Pressure drop control (Pa) is done by the operator through side regulation knobs or automatically across modulation valves under electronic control.

For analyses on thicker samples over 8 mm, a suitable air sleeve can be put on samples before the tests to exclude any air leaks by the sides of test area.

A calibration check metal plate allows to verify periodically the exact reading by the instrument as specified by the Standards UNI EN ISO 9237:97 and ASTM D-737.

The saved results are stored in memory storage and are expressed in following measure units as shown below:

  • Lt/m²/s ( equal to mm/s)
  • m/s
  • Lt/min
  • Lt/h
  • CFM
  • dm3/s
  • cm3/cm2/s
