Abstract: A method and system of remotely monitoring an operational status of electronic discharge devices in an air purification system senses emitted radiation at a location proximate the air purification system, alone or in combination with a determination of an amount of time remaining in an operational lifetime of the electronic discharge device, or an amount of power delivered to at least one of the electronic discharge devices. A determination of the operational status of at least one of the electronic discharge devices is made based on at least emitted radiation, and the status information is transmitted to a remote monitoring unit that receives the status information and displays an indicator of operational status. In one embodiment, the operational status of a UV-C germicidal lamp may be monitored using optically sensitive devices located within a purification system.

Abstract: A portable room air purifier includes a hollow cylindrical air filter disposed within a housing and having an inner surface circumscribing a cylindrical air treatment space and an outer surface. A sorbant material is disposed on the inner surface of the air filter and a germicidal lamp is disposed within the cylindrical air treatment space to emit germicidal light within the space and incident upon the sorbant material on the inner surface of the air filter. A fan is disposed in the housing to draw air from the cylindrical air treatment space through the air filter such that the air enters the filter through the inner surface and exits the filter through the outer surface. The portable room air purifier preferably includes an electrical circuit configured to power the fan and the germicidal lamp when the housing is in an assembled condition, and to deactivate both the fan and the lamp when the housing is disassembled.

Abstract: There is disclosed a multi-lamp germicidal treatment system with interlock. The multi-lamp germicidal treatment system includes two or more mounting assemblies, one of which is coupled to a power source. The mounting assemblies are adjustably coupled to one another. A germicidal lamp may be coupled to each of the mounting assemblies. Power is only provided to each of the germicidal lamps when all of the mounting assemblies have a germicidal lamp coupled therein.

Abstract: A germicidal lamp for harsh environments is disclosed. The germicidal lamp is suited for outdoor installation on an HVAC system or related components. The germicidal lamp is made from materials resistant to splashing water, etc., and includes plural seals to protect the interior of the fixture and prevent leakage or contamination into or out of the HVAC system.

Abstract: A germicidal lamp is disclosed. The lamp's tube has a single stem and may be installed in the lamp's fixture without touching the tube's envelope. The fixture includes a mounting mechanism and a damping mechanism which ease installation and render the tube less susceptible to adverse forces.

Abstract: A method and apparatus wherein a germicidal lamp's tube is positioned in a particular manner relative to the HVAC system such that the system coil and drain pan components are subjected to UVC radiation and an increased flux density of photons emitted therefrom, and the photons are continuously reflected and directed within and through the coil until absorbed. In this manner the flux density of the photons is increased, as well as the dosage of the photons actually applied to a surface or airborne microorganism, minimizing the occurrence of HVAC-sourced bioaerosols and effectively and efficiently killing the mold and bacteria that grow on the coil and in the drain pan of a HVAC system without producing a secondary contaminant.

Abstract: A bag type device (2) for extracting water from oil includes a bag (3) with an outer layer of felt (20) lined by at least one layer (22) of water absorbing laminate. The interior of the bag is composed of a plurality of slit sheets of water absorbing laminate forming a plurality of finger-like strips (35) depending from adjacent the top of the bag. The strips are preferably longer than the length of the bag. The bag and the water-absorbing layers within the bag are supported by a wire ring (30) stitched into a hem around the open upper end of the bag. As oil is passed through the bag, the finger-like strips provide an increased surface area for absorption of water from the oil. The strips can expand inwardly and toward the oil flow to prevent back-pressure build up within the bag.

Abstract: Disclosed herein is a disposable lightweight filter assembly which has a high flow through capacity and which is adapted to be positioned in a relatively small inaccessible space. The assembly includes a cylindrical housing having an air outlet at one end, a plurality of air inlet apertures in the side wall thereof, an offset pleated hollow cone-shaped filter element positioned within the housing and a reuseable air inlet bonnet adapted to be releasably secured to the housing about the air inlet apertures therein for securement of the filter assembly to a hump hose or other air flow coupling. Additionally, the bonnet can include a tubular moisture separator entending from the upstream end thereof.

Abstract: Disclosed herein is an air filter assembly particularly adapted for use in building air conditioning systems. The assembly is comprised of an open ended housing defining an air inlet and an air outlet and having a continuous layer of pleated filtering media extending thereacross and a plurality of pleat support members disposed at the air inlet and outlet ends of the filter housing.
