Abstract: Some embodiments of the invention provide a downdraft assembly capable of ventilating a cooktop including housing with a frame, a fluid box, and a movement assembly with a belt-lift. In some embodiments, the movement assembly can include a vertically moveable chimney. Some embodiments include a chimney with an upper and lower horizontal member and dual fluid inlets. In some embodiments, a first control panel can be coupled to the housing to activate at least one function of the downdraft assembly while remaining substantially stationary as the chimney moves. Some embodiments include a second control panel coupled chimney. Some embodiments include a visor and at least one illumination source configured and arranged to at least partially illuminate the cooktop. In some embodiments, the visor can articulate to control illumination or the flow of a cooking effluent into at least one of the dual inlets.

Abstract: Embodiments of the invention provide a ventilation system comprising a housing that includes a plurality of panels. At least one socket can be defined through at least one of the panels and the socket can be coupled to an electricity source. In some embodiments, the ventilation system can include at least one illumination system that can include a socket interface, an extension member, and at least one illumination device. The socket interface can be configured to engage the socket and the extension member can be capable of moving in a plurality of directions.

Abstract: Embodiments of the invention provide a system capable of reducing negative pressure. The system includes a make-up air system that can be configured and arranged to be installed within a structure, such as a building. The system can also include a pressure switch that is configured and arranged to sense a pressure within an exhaust duct coupled to an exhaust device. The pressure switch can also be configured to communicate an activation signal and a deactivation signal to the make-up air system. In some embodiments, communication of the activation and deactivation signals can be at least partially dependent on the pressure within the exhaust duct. Moreover, the pressure switch can be configured and arranged to be retroactively coupled to at least one of the exhaust duct and the exhaust device.

Abstract: Embodiments of the invention provide a fluid cleaning system. The system can include a housing capable of being coupled to a building structure. At least one first intake, at least one second intake, and at least one outlet are disposed through a portion of the housing. A ventilating assembly is supported within the housing and is capable of generating a fluid flow. In some embodiments, at least one detection apparatus is in communication with the ventilating assembly. At least one shutter is operatively coupled to the housing. The shutter is configured and arranged to move between at least a first position and a second position. At least one filter can he supported within the housing.

Abstract: A ventilation unit for installation in a ventilation system. The ventilation unit can include a motor coupled to a fan element and a power source. The ventilation unit can also include a calibration module having one of a voltage and current regulator for adjusting the performance of the ventilation unit based on at least one characteristic of the ventilation system.

Abstract: Method and apparatus for a range hood. The apparatus can include a housing and a lighting and control unit moveably coupled to the housing. The lighting and control unit can include a user interface and one or more lights. The lighting and control unit can be coupled to a motor that can move a first face of the lighting and control unit outward during use and can move the first face of the lighting and control unit inward when not in use. Some embodiments of the invention provide a fan mounted within the housing and a louver assembly coupled to the housing. The louver assembly can include one or more rotating louvers. In some embodiments, the louver assembly can be rotated downward to access at least one of a filter, a motor, and user interface electronics.
