Dieselcraft Fluid Engineering developed the OC-25 Cyclone Series Centrifuge for internal combustion gas and diesel engines. Engine oil pressure spins the centrifuge rotor at a rate up to 6,000 rpms, generating a centrifugal force 2,000 times greater than gravity. That force separates the solid contaminants from the main oil supply. Contaminant particles less than 2 microns are removed, eliminating the wear and tear on close tolerance metal parts. The solids/soot is stuck to the inside of the rotor, which is easily cleaned at over 15,000 miles. The OC-25 only requires only a 1/4 NPT tapped hole to return oil to the engine. It has a universal mounting plate and comes with all the needed hoses fittings. Minimum requirements are any engine with a sump of at least 5 quarts (no maximum) and 12V.
