The invention relates to a ventilation plant comprising fans for distribution of intake air and exhaust air in branch ducts (9, 19) having openings (10, 20) for the intake air and exhaust air. Tubular filters (11, 21) are sealingly attached to the openings and create a pressure drop of about 200 Pascal, which filters at flow velocities adjusted to about 2-5 m/sec. are acting also as throttling and sound damping devices of the plant.
L'invention concerne une installation de ventilation comprenant des ventilateurs destinés à répartir l'air d'admission et l'air d'évacuation dans des conduits ramifiés (9, 19) présentant des ouvertures (10, 20) destinées à l'air d'admission et à l'air d'évacuation. Des filtres tubulaires (11, 21) sont fixés de manière étanche aux ouvertures, ils créent une chute de pression d'environ 200 pascals, et à des vitesses de flux d'environ 2 à 5 m/sec, ils font également office de dispositif d'étranglement et d'amortissement acoustique de l'installation.
