Multiple Silencers for High-Flow System

Where do you turn when you need to quickly silence 290,000 cubic feet of air in a minute?

Working closely with the local manufacturer's rep for a major fan company, BAM sized, designed, and built eight industrial silencers to handle this huge load. The units are an average of four feet high and three feet wide. 

Much of the pressure drop across the silencer was counteracted by the static regain of a gradual expansion through the unit. At 290,000 cfm, you want as little resistance as possible.
