Typically, labs use standard 100 feet per minute (FPM) velocity fume hoods. With advancements in fume hood design technology, high-performance low flow fume hoods operating at 80 FPM or 60 FPM are available. These hoods can reduce the fume hood exhaust air flow rate by 20% to 40%, thus saving conditioning energy.

Abstract. Compressed air is the most important input for the production processes of many businesses today. Nevertheless, generally, compressed air systems are highly inefficient, resulting in a big amount of wasted energy and cost. Compressed air is very expensive as only 10–20% of the electric energy input reaches the point of end-use.
