Filter regulator lubricator is a pneumatic FRL unit for air compressors. It is used to purify and filter the air source into the pneumatic device and reduce the pressure to the rated air source pressure supplied by the instrument, which is equivalent to the function of the power transformer in the circuit.
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: What is a FRL unit?
The FRL unit includes filter, regulator and lubricator, which is used in pneumatic system. The filter is used to clean the air source. It can filter the water, oil and other impurities in the compressed air. The regulator valve can keep the air source in a constant state, which reduces the damage to valves or actuators due to sudden changes in the air pressure. The lubricator can lubricate the moving parts of the body, which greatly extends the life span of the device.
Filter regulator lubricator is FRL air control unit for air compressor, with pressure gauge and moisture trap. 1/2 inch port size, PT, G, NPT thread type available. It is perfect combo in pneumatic system.
