Cleveland, OH, best known as the hometown of NBA superstar Lebron James, is also home to one of the leading industrial air filtration and ventilation companies in the U.S. right now. 3B Air Systems specializes in air filtration systems with a particular focus on customer success. For these reasons, Mike Krayer, owner and founder of 3B Air Systems, is the focus of this month’s AirPro Rep Highlight.

AirPro engineers designed this custom baghouse fan for a Mississippi River barge that unloads corn and soybeans. This fan connects to a larger zipper duct that moves down the barge. Featuring a 54.2” diameter backward curved wheel, the fan is direct drive with an arrangement 8 configuration and includes a pie-split housing for easy maintenance access to the wheel/shaft.  

The Centrifugal Fan Basics

The most basic answer to the question, “What does a centrifugal fan do?”, is that it moves gas (air), drawing it into the inlet, turning it 90 degrees, and blowing it through the outlet to exit the fan. It moves a higher static pressure than an axial fan, which moves air and gas straight, in one direction. Without air movement inside buildings – whether a room (like in Chet’s example in the video), a house, or an industrial manufacturing facility – things would get dicey. If you were to be trapped in a small room with no ventilation, only breathing in your own exhaled air, you could only survive for so long. Imagine what would happen in a manufacturing facility where there are many other gases and particles at play! If that is all the information on centrifugal fans you were looking for, feel free to stop reading now. For a little more on how they work, carry on.

Our work at AirPro is not always about designing new fans; we often build replacement parts for all fan brands and send field service support teams to oversee installation and ensure the fans are ready for operation. We recently helped a minerals facility when their fan was damaged during operation. Our application engineers recommended replacement of the fan wheel and inlet cone and then our manufacturing team expedited production to provide the fastest delivery possible.
