Abstract
Apparatus for a discharge vent on an air circulation system includes structures for controlling the direction and quantity of airflow. Filter elements may be provided to help reduce contaminants that might otherwise be discharged through the vent. Preferred methods for assembling and using the apparatus are disclosed.
Claims16
Air discharge apparatus for controlling airflow and reducing air borne contaminants, including:
- mounting means for mounting said apparatus to receive air from a discharge vent;
- at least two regulating vents, said vents positioned generally within two or more separate planes;
- and
- at least one filter element for reducing air borne contaminants, said filter element positioned in the air flow path of said discharge apparatus, wherein said filter element includes at least one separate filter device positioned in the flow path of each of said regulating vents.
Air discharge apparatus for controlling airflow and reducing air borne contaminants, including:
- mounting means for mounting said apparatus to receive air from a discharge vent;
- at least two regulating vents, said vents positioned generally within two or more separate planes;
- and
- at least one filter element for reducing air borne contaminants, said filter element positioned in the air flow path of said discharge apparatus, further including at least one slidable damper adjacent to at least one of said regulating vents for controlling air flow therethrough;
- said apparatus further including at least one slidable panel for controlling air flow through another of said regulating vents.
Air discharge apparatus for controlling airflow and reducing air borne contaminants, including:
- mounting means for mounting said apparatus to receive air from a discharge vent;
- at least two regulating vents, said vents positioned generally within two or more separate planes;
- and
- at least one filter element for reducing air borne contaminants, said filter element positioned in the air flow path of said discharge apparatus, including a plenum to receive the output of said discharge vent, and a diffuser at the outlet of said plenum, said diffuser including said at least two regulating vents, said diffuser further including four sides and a center portion, said regulating vents being positioned along said sides, wherein said center portion is generally concave in the direction of the plenum.
Air discharge apparatus for controlling airflow and reducing air borne contaminants, including:
- mounting means for mounting said apparatus to receive air from a discharge vent;
- at least two regulating vents, said vents positioned generally within two or more separate planes;
- and
- at least one filter element for reducing air borne contaminants, said filter element positioned in the air flow path of said discharge apparatus, including a plenum to receive the output of said discharge vent, and a diffuser at the outlet of said plenum, said diffuser including said at least two regulating vents, including a hinge mechanism acting between said diffuser and said plenum to permit access into said plenum.
Apparatus for regulating a discharge vent of an HVAC system, said apparatus including:
- a plenum for receiving the flow from said discharge vents;
- a diffuser with a plurality of regulating vents for directionally controlling flow as it exits said plenum, said diffuser protruding from a surface in which said apparatus is mounted, said plurality of regulating vents being positioned in a non-planar relationship to each other about said protruding portion of said diffuser, in which said protruding portion of said diffuser is pivotably connected to said plenum to permit access into said plenum.
Apparatus for regulating a discharge vent of an HVAC system, said apparatus including:
- a plenum for receiving the flow from said discharge vents;
- a diffuser with a plurality of regulating vents for directionally controlling flow as it exits said plenum, said diffuser protruding from a surface in which said apparatus is mounted, said plurality of regulating vents being positioned in a non-planar relationship to each other about said protruding portion of said diffuser, further including at least one filter element adjacent each of said regulating vents.
