The ventilation system further includes a grille secured relative to the main housing using an attachment feature.

Abstract: A ventilation grille having a trim ring and a plate releasably connected to the trim ring. The trim ring defines an aperture allowing connection of the trim ring to a main housing of a ventilation system defining an internal region in which a blower is located. The plate is releasably connected to the trim ring to allow access to the trim ring aperture for connection of the trim ring to the main housing or blower and disconnection of the trim ring from the main housing or blower.

Abstract: A ventilation device having a housing defining an outlet, a first inlet configured to be in fluid communication with a first room of a building structure and a second inlet configured to be in fluid communication with a second room of a building structure. A blower is located within the housing to move air from the first and second inlet to the outlet. A first damper is located adjacent the first inlet and configured to be operable between a closed position blocking fluid communication between the blower and the first inlet and an open position allowing fluid communication between the blower and the first inlet. A second damper is located adjacent the second inlet and configured to be operable between a closed position blocking fluid communication between the blower and the second inlet and an open position allowing fluid communication between the blower and the second inlet.

Abstract: A flush-mounted, in-ceiling exhaust fan grille for attachment to an exhaust fan housing includes a planar integration flange forming a perimeter of the grille. The integration flange includes a plurality of through holes along the perimeter. An insert may be configured for insertion within the perimeter of the integration flange. A light module may be configured to join within a central portion of the insert while maintaining an opening between an entirety of the light module and the insert. At least one spring may be attached to the insert on a first end and attached to the fan housing on a second end, wherein the at least one spring applies a force drawing the insert towards the fan housing. An exhaust fan may be provided to draw air into the fan housing through the opening between the light module and the insert to be exhausted for proper ventilation.

Abstract: A combined ventilation and illumination system includes a ventilation assembly, a light fixture assembly, and a connector assembly. In an installed position, the system is installed above a ceiling of a room of building structure (e.g., a residence or workplace) to provide ventilation for the room. The system couples a light fixture to ventilation assembly below the ceiling. In the installed position, an air flow cavity is defined between the light fixture and the ceiling, where the cavity allows for air flow around the light fixture and into the ventilation assembly for eventual exhaust beyond the room in which the system is installed. The cavity includes a first critical distance that is sized according to operating parameters of a blower of the ventilation assembly to provide an adequate flow rate of intake air and to provide acceptable sound levels during operation of the system.
