Abstract

1. A room ventilator in which a radial fan (19) is disposed in a parallelipipedic casing (1), a scroll chamber (21) extends as an insert around the fan rotor (20) in the casing (1) and the scroll chamber (21) and a tangential and/or radial passage (28) into which the scroll chamber (21) merges is contrived directly in the block-like insert, the same being made of a sound-damping material such as foam plastic or sponge rubber, characterised in that near an air passage part (27) open on the end face the insert (25) is at such a distance (30', 30") from the adjacent casing wall that the open part (27) extends into an air distribution chamber (32) disposed in the casing (1) before the end face of the insert (25), and the outer long sides of the insert (25) in which the scroll chamber (21) and air passage (28) are contrived have, at least over the longitudinal portion (34', 34") comprising the open part (27) of the air passage (28), bevelled parts (35', 35") extending at an acute angle to the adjacent casing longitudinal walls (3', 3"), the same being formed with air passages, for example, in the form of a grid of apertures (33', 33").
