Mann+Hummel centrifuges for the purification of lubricants and other soiled fluids consist of an outer case and a central spindle, around which a rotor spins at high speed. The lubricant is pumped under pressure into the case of the centrifuge and is transferred to the cleaning chamber of the rotor via the central spindle. After passing through the cleaning chamber, the oil exits again from the lower part of the rotor through two tangentially opposed jets.

Purifiner oil filters are simple, but incredibly effective

The design is simple but highly efficient, where two techniques are used in combination to provide pure oil.
Purifiner has a 100 % cotton filter that removes particles down to 1 mµ from the oil. Water in the oil (combined), is evaporated off in the filter's upper chamber.
