[QUOTE="Wisconsonian, post: 8469883, member: 150618"] If it's fan then that will be true. A dust collector to me is a centrifugal blower wheel, so the load goes up with higher flow at lower restriction, and goes down at lower flow with higher restriction. A 7KW motor instead of a 4KW at the same speed won't affect the blower side, the motor will run cooler and could last longer, but will use more electricity to do the same work. The blower is sized to the motor, all the rest will work better or worse depending on how the ductwork is sized. [/QUOTE]
