<p>A liquid-paint painting booth (10) comprises a painting chamber (11) inside which the liquid paint is sprayed and which is provided with a grille-lined floor (15) for sucking from the chamber an air flow which is then conveyed to a filter unit (20, 26) for filtering the air and separating the overspray with the aid of neutralizing powders which are introduced into the air flow upstream of the filter unit. The air flow is sucked from the chamber through at least one conduit (17), the inlet of which is close to and underneath the grille-lined floor, whereby outlet mouths (23) for a laminar flow of powder transverse to the inlet and substantially parallel to the grille-lined floor of the chamber are provided in the vicinity of the sides of the conduit inlet, so that the laminar flow is passed through by the said air flow leaving the chamber via the conduit.</p> |
