Abstract
Abstract This invention is an apparatus which collects and stores grease discharged from exhaust fan systems of commercial kitchens. There is a means for collecting the grease which is adjustable so that it can be attached to fit most any size commercial exhaust fan. Once the grease is collected, it flows into a means for storing the grease. The means for storing the grease is releasably supported by means for collecting the grease. Thus, the means for storing the grease can be released, the stored grease removed, and then re-attached to the means for collecting the grease. The invention also includes a means for discharging rain water that is collected by the means for collecting grease. Any water which is collected is discharged into the drainage pipe located on the restaurant roof.
