ADJUSTABLE EXHAUST HOOD WITH AIR CURTAIN |
摘要 |
An exhaust hood is disclosed which comprises an open underside and a grease filter defining an exhaust plenum between the hood and the grease filter and a flow path through the grease filter. A shutter-like panel is slidable into the flow path adjacent to the grease filter for blocking a portion of the flow path to adjust the distribution of air across the face of the hood without altering the volume of air flowing through the exhaust hood. Multiple side-by-side panels may be provided and each panel preferably tapers in height across its width. An intake fan is provided at a front portion of the hood to direct room air from adjacent the hood through an intake plenum and downwardly at a front portion of the space beneath the hood to create a partial air curtain which is then exhausted through the hood.
