The cabinet has a perforated plate as its floor which also serves as a fresh air inlet. Since the entire floor is used as the air inlet, the airflow through the interior of the cabinet is uniform and across the full width and depth of the cabinet, virtually eliminating dead areas or channels where leaked gas could accumulate. A tapered roof provides a smooth air handling transition to an exhaust port in the roof. The exhaust port may be connected to a plant ventilation system for removing the exhausted air from the cabinet.Other References
