Abstract

The frames of the Inlets have endcaps and profiles that allow an inlet to be made to different lengths to provide an inlet of a size to provide the proper amount of air needed. Each inlet also has fully insulated blades, sides, and center profiles. The components are preferably foam filled with insulation and have an insulated foam insert on the endcaps together with a center pull so that only a single pull line is needed to operate the inlet.

Claims

1. A ceiling inlet for an air ventilating unit for use in a building having a fan and an actuator that provides air flow to and from an interior of the building to an exterior of the building, said inlet comprising:

a frame suitable for mounting the unit in the ceiling of the building, the frame having an opening providing communication to the exterior of the building and wherein the frame includes end caps combined with longitudinal members extending between and spaced from the end caps to form the opening;

the longitudinal members being sized of a length to form the opening of a desired size;

at least one louver having a bottom edge and a top edge that pivotally mounts the louver between the end caps of the frame so that the louver is moveable from an open position to a closed position, wherein the at least one louver is curved convexly with respect to the interior of the building, and wherein the bottom edge of the at least one louver engages one of the longitudinal members to close off the air flow into and out of the building;

door fillers attached to the interior of the endcaps with respect to the opening, wherein the door fillers are curved convexly with the same curvature as the at least one louver, and wherein the at least one louver engages the door fillers when the at least one louver is in the closed position to prevent air flow into and out of the building; and

the end caps each having an insulated insert and a cover enclosing the insulated insert in the end cap.

2. The ceiling inlet of claim 1 in which the at least one louver is insulated.

3. The ceiling inlet of claim 1 in which there is a center profile combined with the end caps between the longitudinal members, and wherein the at least one louver includes two louvers, wherein each of the two louvers is pivotally mounted on each side of the center profile, each of the two louvers being independently movable.

4. The ceiling inlet of claim 3 in which the two louvers are insulated.

5. The ceiling inlet of claim 1, wherein a rope is connected to the at least one louver such that the actuator adjusts a tension of the rope to move the at least one louver between the open position and the closed position.
