Variable speed blowers offer many benefits. Reducing speed can extend bearing life, reduce heat output, and reduce power during low demand. Increasing speed allows for more performance with smaller units, matching demand in real time,
increased efficiency, and more. Variable frequency drive technology is used to control blower output via varying speed. This technology is ideal in applications with variable operating loads. Blowers integrated with variable frequency drives
can also achieve higher capacities, differential pressures, and higher efficiencies as compared to their fixed-speed counterparts.
