Pneumatic FRL unit is a combination of filter, regulator and lubricator. It can filter the water, oil and other impurities in the compressed air, and keep the air source in a constant state to reduce the damage to valves or actuators of the device.
Features
- The structure of FRL unit is delicate and compact, which is convenient for installation and application.
- The pressed-in self-locking mechanism can prevent the abnormal movement of the set pressure caused by external interfere.
- The pressure loss is low and the efficiency of water separating is high.
- The quantity of oil dripping can be directly observed through transparent check dome.

Tips: Main functions of FRL unit – filter, regulator & lubricator
The compressed air contains a lot of moisture and impurities, it will cause certain damage to the pneumatic system, so it needs to be cleaned before it is connected to the system.
The filter is to filter out the moisture and some impurities in the air. The type of filter element can be selected according to the needs, and the filtration accuracy of the gas can be selected.
The regulator is to adjust the operating pressure of the system to avoid accidents caused by unstable air pressure.
The lubricator is to lubricate the components in the system to extend its service life.
Cost-effective 1/8 inch pneumatic FRL filter regulator lubricator combo is used for filtering water and oil in compressed air and keeping air source in a constant state, with pressure gauge and moisture trap, optional PT, G, NPT thread type, working pressure up to 145 PSI.
