Abstract: A ventilation fan assembly suitable for installation in a ceiling or wall to provide ventilation of the adjoining space, wherein the ventilation assembly includes a fan housing and a removable flange mounting system. The flange system including at least one bracket with a receiver that removably engages an extent of the lower housing edge and a flange that extends from the receiver outward from the lower housing edge. Depending upon the positional relationship of the fan housing and the support surface(s), namely the ceiling, the flange engages an extent of a lower or upper surface of the ceiling. The bracket receiver includes at least one projection that is engages a corresponding aperture formed in the lower housing edge to removably couple the bracket to the housing. The removable flange mounting system improves the installation process and/or the sealing performance of the ventilation fan assembly.

Abstract: Embodiments of the invention provide a ventilation assembly including a scroll assembly that can include a blower assembly including a motor coupled to a blower wheel. Some embodiments include a discharge grid capable of being coupled to the scroll using a coupling pin or snap tabs. In some embodiments, the discharge grid includes a plurality of vertical and horizontal fins, and an outlet restriction. In some embodiments, at least one of the plurality of horizontal fins extends from the outlet restriction to couple with at least one vertical fin to form an aperture. In other embodiments, at least a portion of at least one of the plurality of vertical and horizontal fins includes a flared surface. Some embodiments include a scroll assembly that includes a scroll crescent. In some embodiments, a scroll including a discharge grid and scroll crescent can at least partially guide a fluid within the ventilation assembly.

Abstract: Embodiments of the invention provide a ventilation exhaust fan comprising a main housing adapted to interchangeably receive a upgrade cartridge assembly. The main housing can include a fluid inlet through which fluid is received within the main housing, and a fluid outlet through which fluid exits the main housing. The ventilation exhaust fan can be installed in a structure in place of an existing ventilation exhaust fan assembly. The main housing can provide support to a scroll and a blower wheel positioned within the scroll. A motor may be nestled within the scroll and coupled to the blower wheel. A capacitor including a motor harness and plug can be electrically coupled with the motor. Electrical power can be supplied to the capacitor and motor to cause the motor to rotate the blower wheel to generate a flow of fluid out of the fluid outlet.

Abstract: A ventilation assembly having a main housing that can be pre-installed in a wall or ceiling aperture. A fan assembly can be inserted through the aperture and releasably mounted within the main housing. The fan assembly can be removed from the main housing and replaced without removing the main housing from the wall or ceiling. An accessory component can be releasably mounted to the fan assembly either through the aperture when the fan assembly is mounted or prior to installation of the fan assembly.

Abstract: Embodiments of the invention provide a ventilation assembly comprising a main housing adapted for installation into standard 2?×4? wall or ceiling construction within a building or space. The main housing can include a fluid inlet through which fluid is received within the main housing, and a fluid outlet through which fluid exits the main housing. The ventilation assembly can be installed in place of an existing ventilation exhaust fan assembly, or can be installed in a space where no ventilation assembly has previously existed. The main housing can provide support to a blower assembly, including a scroll and a blower wheel positioned within the scroll. A motor may be nestled within the scroll and coupled to the blower wheel. Electrical power can be supplied to the motor to cause the motor to rotate the blower wheel to generate a flow of fluid out of the fluid outlet.

Abstract: Embodiments of the invention provide a ventilation system comprising a housing. The housing includes an inlet through which air is received and the housing is capable of being installed within a structure. A ventilating assembly can be supported within an interior of the housing. The ventilating assembly can be operable to generate a flow of air and can be in fluid communication with the inlet. The system can include a thermal damper assembly comprising an aperture and a substantially non-metallic curtain. The damper assembly is capable of being coupled to the housing so that the aperture of the thermal damper assembly and the inlet of the housing are in fluid communication with each other. In some embodiments, the thermal damper assembly is configured and arranged to be uncoupled from the housing after the housing has been installed within the structure to provide access to the interior of the housing.
