How A Spinner II Centrifuge Cleans Your Oil

The Spinner II centrifuge is a highly efficient bypass filtration device. To understand how it works, see the video and information below.

Overview of Centrifuge Operation

The Spinner II centrifuge is typically powered only by engine oil pressure, although pump-assisted units are also available. It operates at speeds in excess of 6,000 rpm, generating a force more than 2,000 times greater than gravity. This force extracts solid contaminants from the fluid stream and deposits them on the inner wall of the cleanable rotor as a dense, solid cake.

Flow Through the Unit 

1) Dirty oil enters the separation chamber, flowing up through a hollow spindle.

2) Oil passes through a spinning rotor where centrifugal force 2,000 times greater than gravity separates contaminants from the oil.

3) Contaminants accumulate on the rotor surface as a solid cake.

4) Clean oil exits through opposing, twin nozzles that power the centrifuge up to 4,000 rpm.

5) Clean oil returns to the sump/reservoir from the level control base.
