The Down and Dirty Details on Clearing the Air

Dilution air (air that combines with flue gas) is present in power plants, as well as boiler systems, cooling systems, and other industrial systems that produce dirty air. Each of these requires a dilution air fan to assist in removing the pollutants from the flue gas to clear the air for breathing.

In the optimal application, your inlet duct will have a long, straight pathway into the fan. The recommended length is as much as five to eight times the diameter of your duct. In the real world, it often is simply not practical or even possible. Fortunately, there is a next best option to create the runway the air needs on its way into your centrifugal fan – an inlet box.
