(54) Grill arrangement


(57) A grill arrangement 10 suitable for use in a natural ventilation system. The arrangement includes a plurality of curved vanes 14 which cause air to be accelerated therethrough. The vanes 14 are shaped such that accelerated air is turned towards a direction extending parallel to a ceiling or wall surrounding the arrangement 10. By virtue of a Coanda effect, this causes the air to attach to these surfaces and spread further into a room or other space.
