Branca Air permeability tester is a textile testing instrument useful to determine the exact air speed of a quantity of air that passes perdicularly across a specimen of fabric

The air permeability is a physical feature of textile materials and is considered as the air flow speed that pass perpendincularly through a fabric sample under specific data as requested by the reference Standard: test area, pressure drop and time (e.g. ISO 9237 or ASTM D-737)

An HMI touch panel allows the user to define test settings and monitor values.
