Don't have enough knowledge to know but the motor draws some 5.x
A @ 120V or almost 3 @ 230V so its not exactly computer power
kind of fan country but its not that big. (There are some models available
with a 2 m blade system and they run somewhat over a kW in draw at
full output but I don't need anything of that size for this iteration!)

Fan system is some 100 m from the main computer - - - - and as wiring
isn't anywhere close to 'free' there will be a ucontroller of some type in
the facility which will be monitored at the very least from a distance.
(Still will be some 40 ish m from the control to the furthest point of
control! This is not 'standard' residential stuff - - - grin!)

Thanks for the ideas!
