Let’s face it, deciding to replace your air handling unit fan is no minor consideration. Sometimes a catastrophic fan failure means you have no choice but to replace the failed fan. Sometimes, the fan has yet to fail, and there are other considerations such as performance or maintenance.
Perhaps the biggest consideration for most clients replacing AHU fans is cost. Commercial grade AHUs, their fans, and other internal components can be costly. Operating belt-driven air handling unit fans requires regular maintenance and can be energy-intensive.
Making the best decision about what kind of AHU fan to use today can have major cost implications as the unit runs over the course of many years.
