ABSTRACT:
A greatly extended plenum chamber, comprising a plenum or exhaust chamber and a plenum extension connected thereto, is employed in combination with grease filters which operate by impingement and by centrifugal action. Furthermore, a stream of air is directed against the upstream surfaces of the filters. The result of the combination is a surprisingly effective removal of grease and smoke from cooking fumes, with consequent minimization of grease coatings on the surfaces of the plenum chamber and of the exhaust blower connected thereto. When space does not permit vertical installation of a large extended plenum chamber, portions of such chamber may be inclined from the vertical and/or may be replaced by a plurality of smaller plenum extensions.
In an additional embodiment, the effect of a very large plenum extension is obtained by a single and much smaller plenum extension. This is achieved by (a) using a duct (to the exhaust blower) which has a diameter larger than the depth of the plenum extension, and (b) placing a relatively small air deflector below the connection between such duct and the plenum extension.
Other features of the apparatus and method include (a) a unitary construction which is substantially completed at the factory and is easily and unitarily installed at the job site by dropping it into a hole in the ceiling, and (b) an electrostatic precipitator which is sometimes employed where smog regulations are particularly stringent.
