I have industrial centrifuge designed for filtering liquids such as WVO and other liquids. All food grade materials, stainless steel, sanitary connectors, etc. PLC controlled. 3 phase motor. Could be the centerpiece for a small industrial scale waste oil filtering setup for SVO or Biodiesel.
The unit is practically new and has only been used a few times.
I've included a similar picture, however, I can arrange for actual pictures and demo.
