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.

Abstract: A method of assembling a hanger assembly for mounting to a fan housing in a building includes, providing a first bracket having a first end and a second end, the first end having a first flange and a second flange, providing a second bracket having a first end and a second end, the second end having a first flange and a second flange. The method further includes inserting the second end of the first bracket in a first direction into a first end of a third bracket, inserting the first end of the second bracket in a second direction, opposite the first direction, into a second end of the third bracket, and coupling at least one spacer to the third bracket, the spacer extends from the third bracket in a third direction, substantially perpendicular to the first direction.

Abstract: A hanger assembly configured to mount a fan housing in a building including a first support having a lower surface and a second support. The hanger includes a body having a first end engageable with the first support and a second end engageable with the second support. The body is connectable to the fan housing to support the fan housing between the first and second supports and is adjustable to change a length defined between the first and second ends. The first end includes an outwardly extending flange, which is engageable with the first support to orient the body and the fan housing relative to the lower surface of the first support and to maintain a predetermined distance between the lower surface of the support and a lower surface of one of the fan housing and the hanger body.

Abstract: The present invention provides, among other things, an exhaust vent fan including a housing having an inlet through which air is received within the housing and an outlet through which the air exits the housing, a fan wheel supported in the housing and operable to generate a flow of the air out of the outlet, a louvered first grille positioned across the inlet, a heating element supported in the housing, and a second grille supported on the housing and being moveable relative to the first grille while the first grille is secured to the housing to direct a heated air flow from the heating element out of the housing.
