• Gravity causes natural settling in a diesel tank. Due to solids and liquids all having different densities, solids will settle at the bottom of the tank (i.e. rust, grit and sand, sludge) then followed by the denser (heavy phase) liquids (i.e. water) then the least dense liquids (light phase, i.e. diesel fuel).

• A pick up tube attached to a suction hose pulls the contaminated fuel from the tank into the centrifuge. Our filter screens or canisters pick up most of the large particle solids before they enter the centrifuge.

• The centrifuge then uses centrifugal force, spinning the fuel outward away from the axis, thus opposite to the direction of gravity. This force causes a separation of the solids and heavy phase liquids (water) from the light phase or clean uncontaminated diesel fuel. Any and all solid particles stay stuck inside the centrifuge bowl due to the centrifugal force, water exits through the heavy phase outlet into a holding tank. The clean uncontaminated diesel exits through a clean outlet which is discharged back into the tank (also through a hose attached to a release tube).
