How does the Spinner II® centrifuge work?

The Spinner II® centrifuge is a highly efficient bypass filtration device. It diverts a small sidestream of oil for processing and returns clean oil to the crankcase. Powered only by engine oil pressure, the centrifuge operates at speeds in excess of 6,000 rpm, generating a force more than 2,000 times greater than gravity. This force slings contaminants smaller than one micron out of your oil and packs them into a dense cake on the wall of the cleanable centrifuge bowl. A Spinner II® centrifuge flows up to two gallons of oil every minute, allowing it to clean the entire sump capacity of a typical heavy-duty engine 10-15 times an hour.
