ABSTRACT:
An exhaust hood may be fabricated having a plurality of slots disposed at one side of the cavity formed by the hood to form a substantially streamlined, and uniform air flow across the cavity to efficiently entrain smoke laiden air without requiring large volumes of air flow. This type of air flow pattern within the cavity is obtained by appropriately baffling the air supplied to the multiple slots, forming a number of high velocity venturi slots, and canting oppositely disposed inlet filters away from the outlet slots. The uniform air flow creates a low pressure area which then draws underlying smoke laiden air upward. The hood canopy may be provided with a second source of tempered air to direct comfort condition air through a slot on the face of the hood along the cooking line for the safety and comfort of the workers below.
