PANEL FOR AIR CONDITIONING AND ACOUSTIC ISOLATION OF ROOMS

摘要

A panel for the guidance of an air flow comprises a body of sheet material provided on opposite sides with mutually offset nozzles in the form of hollow bosses or perforated ribs converging outwardly. The nozzles are formed by alternately bending the sheet material in opposite directions whereby a protuberance on one side corresponds to a depression on the other.
