HOOD

A hood is provided to mount an optical catalyst filter to a path of a case for removing a corrugation pipe, which connects the path to an outlet and generates back pressure, thereby lowering back pressure and reducing motor rpm. A hood includes a case formed with an inlet, an outlet and a path conne...

More Information
Summary:A hood is provided to mount an optical catalyst filter to a path of a case for removing a corrugation pipe, which connects the path to an outlet and generates back pressure, thereby lowering back pressure and reducing motor rpm. A hood includes a case formed with an inlet, an outlet and a path connecting the inlet to the outlet. A discharge fan is mounted in the path and driven by a discharge motor A HEPA filter, an optical catalyst filter, and an ozone filter are mounted in the path. The optical catalyst filter has an optical catalyst supporting element(134) mounted in the path and formed with a plurality of fine paths(134a) in the lengthwise direction of the path, wherein the supporting element contains optical catalysts. Electrodes(133,135) are mounted at an inlet and an outlet formed at both ends of the supporting element in the lengthwise direction of the path.
