• a ventilation unit comprising an insulated double chamber plenum box, a ventilation opening, and an air flow regulator,
• the linear air diffuser further comprises a mounting profile mounted to an air outlet part of the ventilation unit, and an air diffuser profile mounted to the mounting profile, and
• the air diffuser profile consisting of two lateral sides with slits, wherein the two lateral sides are connected at an acute angle and a drop-shaped air deflector connected at a top of the two lateral sides, wherein:
• the mounting profile is formed of an H-profile having a perforated horizontal connection surface, and an upper and a lower part, and a downwards duct for attaching a stretch ceiling material is located at bottom of external sides of the lower part;
• on an outer side of the downwards duct is a mounting bracket at a right angle, where an external wall of a vertical part of the mounting bracket has vertical grooves and the mounting bracket is intended for attaching a suspended ceiling element;
• at a lower end of inner sides of the lower part of the mounting profile is a groove which opens downwards for attaching the air deflector profile;
• each of the two lateral sides of the air deflector profile has at a middle a vertical protrusion with a widened end for mounting the air deflection profile to the groove of the mounting profile and a bottom edge of each lateral side of the air diffuser profile projects horizontally for additional support for the suspended ceiling element and for covering a connection point of the stretch ceiling material and the suspended ceiling element.
