Branca Air permeability

 

Branca Air permeability measures the exact air velocity of a an air volume to cross perdicularly FABRICS

The Air Permeability is a physical feature of fabrics and it is considered as the velocity of the air that pass perpendicularly across fabrics under specific requirements expressed from Standard as e.g. test area, pressure drop and time (e.g. ISO 9237 or ASTM D-737)

An HMI Touch Screen allows the user to define test settings and test monitor.
