Simply, this doesn’t make sense to me…

I assume you’re discussing the Super Dust Deputy (SDD); as the smaller ‘Dust Deputy’’ is intended to sit pre-vacuum cleaner. Cyclones are inherently self-regulating; that is, only so much air can be pulled through a 4” or 5” or 6” opening; with inherent line static pressure and pressure-drop getting in the way: the line opening constricts the throughput. Putting an outsized impeller and motor onto a too-small airflow (limited by either the run size (6” or 8” main runs), or too-small a coupling hole) will serve to ‘starve’ the impeller. – I’m not sure I explained that clearly…

I used the SDD for years connected to a 2hp motor, and it worked great.
