Abstract

A supply air terminal device intended for a room and comprising a supply air chamber (4) to which supply air is delivered, and a number of air outlet nozzles (30-33) which are distributed along a length direction of the chamber, wherein the nozzles are adapted to provide a drop in pressure of at least 70 Pascal, and an air flow rate of at least 8 metres per second, wherein the nozzles are formed to provide but a low noise build-up during the throughflow of supply air, in a known manner. The supply air chamber (4) is surrounded by a housing (8) that includes an opening (13), which extends along that part of the chamber (4) equipped with said nozzles. The opening (13) is screened or shielded by an air-permeable grating (14) and extends around at least 20 percent of the housing periphery, transversely to the long direction of the chamber (4). The nozzles (30-33) are directed so that the air jets issuing from said nozzles will impinge on the housing walls at a distance from the housing opening (13).
