a motor housing extending between the upper frame portion and the lower frame portion and having two or more vane apertures formed on the motor housing; a plurality of secondary frame pieces each having an upper nose portion and a lower nose portion, wherein the plurality of secondary frame pieces include a first end cap connected to the upper frame portion at the upper nose portion and the first end cap connected to the lower frame portion at the lower nose portion, a second end cap of the plurality of secondary frame pieces connected to the upper frame portion at the upper nose portion and the second end cap connected to the lower frame portion at the lower nose portion, wherein when the first end cap and the second end cap are connected to the upper frame portion and the lower frame portion, one or more apertures (13, 13') of the assembled modular frame (12, 12', 12") are defined by the motor housing, the first end cap, the second end cap, the upper frame portion and the lower frame portion; a plurality of vanes (36, 37, 39) formed by extrusion, rotatably positioned within the one or more apertures (13, 13') for controlling the amount of air flowing through the one or more apertures (13, 13'), wherein a first end of each of the plurality of vanes (36, 37, 39) is rotatably connected to one of the first end cap or the second end cap and a second end each of the plurality of vanes (36, 37, 39) is rotatably connected to the motor housing; and a transmission mechanism connected between the plurality of vanes (36, 37, 39) for causing the plurality of vanes (36, 37, 39) to rotate between a closed position and an open position in response to actuation of a motor contained in the motor housing, wherein at least one of the plurality of vanes (36, 37, 39) is a driven vane that is connected to and receives rotational force from the motor, which is then transmitted through the at least one drive vane to all of the plurality of vanes (36, 37, 39) through the transmission mechanism, characterized in that each of the plurality of primary frame pieces having a hollow bore extending through the each one of the plurality of primary frame pieces forming an aperture at the first end of the hollow bore and an aperture at the second end of the hollow bore a plurality of primary frame pieces, formed by extrusion with each one of the plurality of primary frame pieces having a first end, and a second end; an upper frame portion of the assembled modular frame (12, 12', 12") formed from at least one of the plurality of primary frame pieces; a lower frame portion of the assembled modular frame (12, 12', 12") formed from at least one of the plurality of primary frame pieces; a motor housing extending between the upper frame portion and the lower frame portion and having two or more vane apertures formed on the motor housing; a plurality of secondary frame pieces each having an upper nose portion and a lower nose portion, wherein the plurality of secondary frame pieces include a first end cap connected to the upper frame portion at the upper nose portion and the first end cap connected to the lower frame portion at the lower nose portion, a second end cap of the plurality of secondary frame pieces connected to the upper frame portion at the upper nose portion and the second end cap connected to the lower frame portion at the lower nose portion, wherein when the first end cap and the second end cap are connected to the upper frame portion and the lower frame portion, one or more apertures (13, 13') of the assembled modular frame (12, 12', 12") are defined by the motor housing, the first end cap, the second end cap, the upper frame portion and the lower frame portion; a plurality of vanes (36, 37, 39) formed by extrusion, rotatably positioned within the one or more apertures (13, 13') for controlling the amount of air flowing through the one or more apertures (13, 13'), wherein a first end of each of the plurality of vanes (36, 37, 39) is rotatably connected to one of the first end cap or the second end cap and a second end each of the plurality of vanes (36, 37, 39) is rotatably connected to the motor housing; and a transmission mechanism connected between the plurality of vanes (36, 37, 39) for causing the plurality of vanes (36, 37, 39) to rotate between a closed position and an open position in response to actuation of a motor contained in the motor housing, wherein at least one of the plurality of vanes (36, 37, 39) is a driven vane that is connected to and receives rotational force from the motor, which is then transmitted through the at least one drive vane to all of the plurality of vanes (36, 37, 39) through the transmission mechanism, characterized in that each of the plurality of primary frame pieces having a hollow bore extending through the each one of the plurality of primary frame pieces forming an aperture at the first end of the hollow bore and an aperture at the second end of the hollow bore
