Abstract

An air treatment system includes at least one chamberless tube having air inlet and air outlet ends and a UV light reflective interior surface. The tube has an inside diameter and is preferably made from a UV grade aluminum. At least one tubular UV light source corresponding to the at least one chamberless tube is disposed generally coaxially within the UV reflective tube. The UV light source has an exterior light emitting surface spaced from the tube reflective interior surface. The light emitting surface has an outside diameter. Airborne pathogens in air moved through the tube and over the UV light source are eliminated.

Claims

1. An air treatment system comprising:

at least one chamberless tube having air inlet and air outlet ends and a UV light reflective interior surface;

said tube having an inside diameter;

at least one tubular UV light source corresponding to said at least one chamberless tube;

said light source being disposed generally coaxially within said reflective tube and having an exterior light emitting surface spaced from said tube reflective interior surface; and

said light emitting surface having an outside diameter;

whereby airborne pathogens in air moved through said tube and over said UV light source are eliminated.

2. The air treatment system of claim 1 wherein said UV light source is disposed in said tube such that the distance between the exterior light emitting surface of said light source and the reflective interior surface of said tube is in the range of ¼

to ¾

the outside diameter, of said light emitting surface.

3. The air treatment system of claim 2 comprising:

an air filter mounted about the air inlet end of said tube for filtering out particulates from air moving through said tube.

4. The air treatment system of claim 2 comprising:

an air mover mounted about one end of said tube for moving air through said tube.

5. The air treatment system of claim 2 wherein the distance between the exterior light emitting surface and the reflective interior surface is generally ½

the outside diameter of said light emitting surface.

6. The air treatment system of claim 2 wherein said tube comprises a UV grade aluminum.

7. The air treatment system of claim 1 wherein said UV light source is in the range of 30 to 100 watts.
