The LM300 Series Level Maintainer automatically adds oil to the crankcase as needed to keep the lube level normal.
Most models have built-in switches that will alarm and/or shut down the equipment if the makeup supply is depleted and engine oil level falls or if overfill conditions exist. The LM300 can be used in engines, compressors, pumps and coolers. LM300 Series EX models (explosion-proof) are CSA certified for Class I, Division 1 Hazardous areas.
