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. |
