Abstract
A ventilation diffuser of the type used as a ceiling ventilation outlet and characterized by its adjustability to produce the desired flow output, to produce the desired directional flow pattern around it, to rooms of different sizes and to different positions relative to the inside walls of a building, and to ventilation outlet ducts of different sizes. This ventilation diffuser comprises a receptacle including a bottom and an open end opposite the bottom, a ventilation deflector adjustably displaceable in in-and-out direction in the open end and curved to produce an outward flow parallel to and against the ceiling, frictionally engaged male and female connection members to readily adjust the ventilation deflector relative to the receptacle and thus the ventilation output, a gate device having selectively tearable tabs regulating the ventilation output to selectively define a desired directional flow pattern around the diffuser, and clips to snappingly secure the diffuser in an aperture of the ceiling.
