Product Code : FRL
Product Description

Pneumatic FRL 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 housing to aid in oil flow rate adjustment. 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 interferes with pressure regulator operation, oil is separated from the air stream and drained by the filter, and very little or none is delivered to connected equipment.
