Zero room air requirements. The Fume hood exhaust is equal to the auxiliary supply air, thereby zero room air is required. With the sash in the ½ open position and face velocity of 100 feet per minute, the CFM required equals the air supply. The hood exhaust air plus auxiliary air make up for room supply deficiencies. Since expensive tempered room air is not required, Auxiliary Air Fume Hoods provide energy savings.
