  • High efficiency grease filter cartridge
    Publication number: 20070023349
    Abstract: A grease filter has a filtering portion configured such that fumes enter a major face thereof and flow through a grease extraction filter therewithin in a direction parallel to the major face. A frame that fits into an opening of a hood defines a box structure that is configured to allow flow from the end (or ends) of the filtering portion where flow exits.

  • FUME TREATMENT METHOD AND APPARATUS USING ULTRAVIOLET LIGHT TO DEGRADE CONTAMINANTS
    Publication number: 20060219235
    Abstract: An ultraviolet treatment chamber for treating exhaust streams, particularly those containing organic particulates, utilizes ultraviolet light energy very efficiently. This is done by setting up a circulating flow in a treatment plenum so that all of the effluent experiences a substantially uniform residence time without the need for baffles or other flow controllers that would block the ultraviolet light.
