According to the company, the UniFlow Auxiliary Air Fume Hood will cut costs when there is a shortage of air in the lab, compared to changing or enlarging a building’s air handling system. The sash has been designed in the half-open position and face velocity of 100 feet per minute so that 50% of supply air is required to make up for the exhaust air. Fume hoods are available in 4’, 5’, and 6’ widths. The access panel is removable to access ducting connections and electrical services from a single-point electrical box, 115/60Hz AC operation.
