Abstract
A gas cabinet and a method of controlling air flow through said gas cabinet. The gas cabinet includes an enclosure; a damper having at least two flow rate positions; an exhaust outlet; a set of sensors; and a programmable logic controller configured to change a flow rate position of the damper from a first flow rate position to a second flow rate position based on the state of the sensors. The method includes using the damper to lower the amount of exhausted air required under normal operating conditions and using the damper to increase the amount of exhausted air when a possible gas leak is detected.
