What is a lubricator?
A pneumatic lubricator injects an aerosolized stream of oil into an airline to give lubrication to the internal working parts of pneumatic tools and to other devices such as actuating cylinders, valves and motors. A lubricator should always be the last element in an FRL (Filter-Regulator-Lubricator) unit. If an FRL is connected “backwards” with incoming air connected to the lubricator, oil-laden air will interfere with pressure regulator operation. Oil is separated from the air stream and drained by the filter, and very little or none is transported to connected equipment.

How does a lubricator work?
Lubricators are an unusual conditioning device that adds a small quantity of oil or mist to the air, upon leaving the regulator. While passing through, the flow increases in velocity. Oil is pulled up by the venture effect and radiated as an aerosol at the outlet port. The needle valve is positioned within a clear polycarbonate or nylon housing to aid in oil flow rate alteration.

How do we maintain a lubricator?
Airflow has a huge effect on the kind of lubricator that should be identified. For instance, irrespective of size, more or less the same types of lubricators may not be able to distribute enough lubricant for a given airflow, while others may every time dispense too much. Hence, dispensing too much lubricant can form a mess and is improvident.  Besides that, if a pneumatic system is allowed to run dry for a lengthy period after getting too much lubricant, residual oil may custom a baked-on varnish on internal surfaces, delaying the proper operation, performance and service life.
