Abstract (en)
[origin: CA3176728A1] The invention relates to a jet ventilator for ventilating tunnels, in particular road tunnels, to a jet ventilator system and to a method for producing a jet ventilator for ventilating tunnels. In particular, the invention relates to a jet ventilator for ventilating tunnels, in particular road tunnels, comprising a ventilator unit (106) for generating an air flow, a noise damper (110, 130) arranged on the ventilator unit (106), with a proximal portion (112) and a distal portion (116) adjoining the proximal portion (112), characterized in that the distal portion and the proximal portion are at an angle (120, 122) to one another.
