The Off Line/Filter System, or OLFS for short, can be used in any hydraulic, lubrication and transmission system. The filter unit has its own motor-pump combination. This engine-pump combination takes in oil from the reservoir (or e.g. from the crankcase of an engine). Along the way, the dirty oil is pumped through the filter, filtered, and then pumped back into the tank. The tangible benefits of clean oil translate directly into fewer faults, less wear, longer oil life, extended service intervals and structural cost savings. Show more
