The LM301 Lube Level Maintainer automatically adds oil to the crankcase as needed to keep the lube level normal. A built-in switch will alarm and/or shutdown the equipment if the makeup supply is depleted and engine oil level falls or if overfill conditions exist.

The LM301 has a high visibility "frog eye" lens, optional pipe or universal mounting brackets, and optional inlet orifices for low to high pressure applications. The unit is made of die cast aluminum (enclosure type 4 certified) and has a rigid polyurethane foam float.
