In-line, automated, duct-washing apparatus
First Claim
1. An in-line apparatus for sanitizing an internal lumen of a duct system, the apparatus comprising:
- a housing disposed in-line with the duct system to be sanitized;
at least one air inlet manifold and at least one air discharge manifold defined in the housing, wherein both the air inlet manifold and the air outlet manifold can be switched between an open position and an air-tight closed position;
an auto wash sub-assembly disposed within the housing; and
an ultraviolet or ionizing radiation source disposed within the housing such that air entering the housing via the air inlet manifold is exposed to the UV or ionizing radiation source for a time sufficient to kill microbes present in the air within the housing.

Abstract
Disclosed is an in-line apparatus for sanitizing an internal lumen of a duct system. The apparatus includes a housing with an air inlet manifold and an air discharge manifold defined in the housing; an auto wash sub-assembly disposed within the housing; and an ultraviolet or ionizing radiation source disposed within the housing. The apparatus may also include a one cooling coil, a burner, a steam unit disposed, and/or an electrostatic sub-assembly disposed within the housing. In a preferred arrangement, a pogrammable logic controller is operationally linked to the auto wash sub-assembly, the ultraviolet or ionizing radiation source, the cooling coil, the burner, and the steam unit, and can control these elements according to user-defined, pre-set modes. The device functions to sanitize air that is circulated throughout rooms and buildings via duct systems.

12. An in-line apparatus for sanitizing an internal lumen of a duct system, the apparatus comprising:
-
a housing disposed in-line with the duct system to be sanitized, the duct system having a plurality of vents defined therein;
at least one air inlet manifold and at least one air discharge manifold defined in the housing, wherein both the air inlet manifold and the air outlet manifold can be switched between an open position and an air-tight closed position;
an auto wash sub-assembly disposed within the housing;
an ultraviolet or ionizing radiation source disposed within the housing such that air entering the housing via the air inlet manifold is exposed to the UV or ionizing radiation source for a time sufficient to kill microbes present in the air within the housing;
a positive-closing duct system (PCDS) comprising, in combination, a corresponding door and a actuator for every vent present in the duct system to be sanitized, wherein the actuator is dimensioned and configured to move its corresponding door between a closed position and an open position;
a programmable logic controller operationally linked to the auto wash sub-assembly, ultraviolet or ionizing radiation source, and the PCDS, wherein the programable logic controller is user-programmable to operate the auto wash sub-assembly and the ultraviolet or ionizing radiation source in pre-set modes and to move the doors of the PCDS between the closed and open positions. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
