Features and Advantages of Motorized Impellers

CMI Backward Curved Motorized AC ImpellerWhen it comes to commercial / industrial cooling, it may seem that there are a lot of choices, making it hard to know which is best. What’s important to know is that for many applications—from electronic cabinet cooling to air filtration, fume hoods, heat exchangers—motorized impellers offer distinct advantages over other air movers. There are many features and advantages of motorized impellers.

They work particularly well in electronics cabinets with moderate to high static pressure, and are available with AC, DC, and EC motors. Their compact design, coupled with their superior performance, means they provide better value than other options.

All of our motorized impellers feature backward curved (BC) blades.  BC impellers offer many advantages over forward curved (FC) impellers, providing the highest efficiency of all centrifugal fan designs while being quieter and generating significant static pressure.
