We have been building centrifuges for over 10 years (see History page for a Visual History) This bowl design sets a new standard for simple centrifuges world wide. Safe, easy to maintain, and inexpensive to run, this is the skimpiest machine on the market. No need for 3-phase power or troublesome pumps. This centrifuge is gravity fed and uses standard household single phase power. We estimate that we have processed over 7500 gallons of waste oil, waste vegetable oil, bio-diesel, and hydraulic oil since building our first machine. We have saved tens of thousands of dollars by recycling waste products. The machine is simple enough anyone can run it. It makes us money 24 hours a day.
Please feel free to tour our site. We have a number of videos, images, FAQ and history to help you understand what a simple centrifuge can do for you. We are always working on new ideas and posting our latest findings online so check back often.
