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: Some embodiments of the present invention provide a combination lighting and ventilating apparatus for installation in a structure. The apparatus can include a main housing having a first aperture that defines a ventilating inlet and a lighting outlet, a lamp housing recessed within the main housing, having first and second apertures spaced a distance from one another, and having a portion that extends outside of the main housing, and a lamp recessed within the lamp housing and the main housing. In some embodiments, the apparatus further includes a fan positioned to draw air into and through the first aperture of the lamp housing, around the lamp, and through the second aperture of the lamp housing. In another aspect of the invention, a method of lighting and ventilating a room using a combination lighting and ventilating apparatus is provided.

Abstract: A ventilation exhaust fan is provided, and in some embodiments includes a housing adapted to interchangeably receive a first module having a first support plate and a second module having a second support plate. Each of the first and second modules have at least one of a motor and a fan wheel operable to generate a flow of fluid into and out of the exhaust fan. At least one of the motor and fan wheel of the first module is different from the motor and the fan wheel of the second module, respectively.

Abstract: A ventilating and heating apparatus for installation in a building structure. In some embodiments, the apparatus includes a main housing in which is located a ventilating fan assembly and a heater fan assembly having a heater and a discharge duct terminating in a discharge outlet, wherein the heater is located within and connected to the discharge duct of the heater fan assembly. The heater can be shielded from the discharge outlet by at least one interior wall of the discharge duct. In some embodiments, the discharge duct can have a tapered portion approaching the discharge outlet.

Abstract: A backshelf compensating exhaust hood includes an upper wall passageway for forming and redirecting an induction air stream into and through an exhaust chamber to an exhaust passageway, the upper wall passageway extends through the upper wall to a smooth curved reverse passageway redirects the air into a short slot which discharges a stream into the upper end of the exhaust chamber. A forward tilted filter is located in the exhaust chamber to form the back wall of the exhaust chamber and with the lower end spaced inwardly of the upper end and with the upper portion aligned with the induction air stream. The filter is oriented to define an essentially right angle with the interior upper wall of the exhaust chamber. The top wall of the exhaust chamber extends inwardly and upwardly slightly to the filter. The induction air supply passageway is a relatively large passageway which has a depth which is a multiple of the depth of the slot.
