Waste Oil Recovery and Purification Systems

The Fuel Factory is a plug and play complete system for processing waste motor oil or waste vegetable oil

The Fuel Factory is a set of precision centrifuges driven by an industrial duty gear pump that can run continuous for 24 hours with out a problem and will clean 216 gallons of waste oil per hour.

The Fuel Factory will clean any waste motor oil, transmission fluid or vegetable oil without any filters.

The Fuel Factory is built on a precision heavy steel plate that hold the two centrifuges, pump, motor, switch and the easy pour 12″ pour opening.

The Fuel Factory is designed to fit inside and just below the top edge of a standard 55gallon open top drum. By being below the top a 1/2 inch there are NO SPILLS on the ground. Everything goes in the Fuel Factory. 

The Fuel Factory is easily removed from the drum if needed. 
Process the oil in one drum then use the same pump to transfer the finished product to a storage tank.

* Time depends on oil temperature and time it take to heat to operation temperature of 160-180F
Individual parts are available to configure a smaller system if needed.
