I am using switched reluctance brushless vac motors rated at 1500 hrs. They sustain the lift over distance which gives them a leg-up on a lot of the other electro vac motors. Recovery tanks are small which gives an almost instant rise time. I would say the components would be around $8000 plus, depending on options. I am available for anyone to come here and see for themselves that what I say is true. Just give me a heads-up.
