Lube Oil Centrifugation is a lube oil cleaning method that uses centrifugal force to pull matter of different densities away from one another. The cleaned oil is directed back into the process while the contamination is contained in a dedicated compartment for disposal.
Lube oil filters are a lube oil cleaning technology that use filters of varying mesh sizes to capture solids. Most commonly, the solids are captured in a disposable filter cartridge and are replaced regularly.
Coalescers are a lube oil cleaning technology that remove water from the lube oil. This water removal can be performed only after the lube oil is practically particle free. Most often the coalescer module is added to a filter system so that both solid particles and water are removed from the lube oil
