Kitchen Exhaust Hood is the most obvious and noticeable part of the kitchen exhaust system. The hood is located directly above the cooking equipment, hanging over the stove or fryer and above the cook’s head. The hood collects all the heat and incoming grease vapors being produced from the cooking equipment. Inside the hood, baffle-filters collect and filter the grease vapors before they enter the ductwork. This makes it so less grease finds its way into the ductwork and thus gets expelled into the air outside the building.
