Take advantage of the Closed System Opto-Matic Oiler for equipment when maintaining a constant level of oil in the oil housing is critical. The closed system design eliminates contamination ingress during the breathing process as well as possible oil mist being pushed out of the berather or oiler vents.

Control the oil level externally through the adjustable collar. The closed system oiler is configured with a 1/8 NPT port, which accommodates a vent line back to the housing, facilitating pressure balancing between the oiler and the oiler housing.
