See pics for the motor and blower specs. Runs on household current, 15 amp minimum. I can let you see it run. Although it's not labeled, I believe this is a Dyna-Lite, made by Dyna-Vac Equipment (see last pic from their website). Dyna-Vac doesn't allow their prices to be published, but comparable machines cost around $7000.
This has been in storage for several years, so I would recommend preventative maintenance before putting it to use, such as lubing the Roots blower through the attached grease fittings. Includes the blue hose, about 10' in length. This is a very heavy machine. You'll need a ramp, a come-along or winch, and straps.
