Abstract
A ventilation element for mounting in a partition opening having a tubular connector having an open end for admitting air to a room, a cover for regulating the quantity and direction of incoming air, and a tubular diffuser which telescopically engages the connector and mounts the cover for adjustment toward and away from the open end of the connector. The diffuser has a cylindrical wall extending less than 360.degree. to provide a radial inlet opening between the connector and the cover. The diffuser wall is engaged with the connector by fasteners and oblique slots which effect axial movement of the diffuser when it is rotated relative to the connector whereby the diffuser may be adjusted axially relative to the connector, and the connector and diffuser together may be adjusted circumferentially in the partition opening.
