ABSTRACT:
The makeup air device includes a front chamber, a lower wall of which is adapted to force rising smoke and the like into an intake of a grease extraction ventilator. A depending passage at the lower front of the device has an air outlet which discharges air toward the ventilator intake. An adjustment baffle having a forwardly slanted lower flange is moved in the outlet between a position of maximum flow and a position of no flow. Louvers in the front wall of the chamber above the passage are adjustable, so that different amounts of fresh air may flow into the room in which the cooking equipment is placed.
