Global Brass And Pneumatics

A pneumatic lubricator injects an aerosolized stream of oil into an air line to provide lubrication to the internal working parts of pneumatic tools, and to other devices such as actuating cylinders, valves and motors.Compressed air enters the inlet port and passes over a needle valve orifice attached to a pick-up tube. This tube - often equipped with a sintered bronze filter - is submerged into a reservoir bowl filled with light machine oil. Oil is pulled up by the venturi effect, and emitted as an aerosol at the outlet port. The needle valve is typically situated within a clear polycarbonate or nylon housing to aid in oil flow rate adjustment. Some Compressor oils and external
