Ross Controls MD451MSB52 Lubricator

Ross Controls MD451MSB52 is a 3/4 in NPT sight-feed lubricator in the MD4 Full-Size Series that injects lubrication into the compressed air stream for downstream pneumatic components. It operates from 0 to 200 psig and supports a maximum flow of up to 210 scfm, making it suitable for multiple tool stations in automated systems. The unit uses a 9-ounce polycarbonate bowl with a clear sight dome and a sight-feed design that provides a visible oil drop indicator, allowing quick verification of lubrication delivery. Typical applications include lubricating pneumatic actuators, cylinders, and valves in manufacturing and automation environments. This model is sized for a 3/4 in NPT port consistent with the MD4 family’s full-size lubricators.
