Air FRL unit is a combination of filter, regulator and lubricator used for air compressor. 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
- Quick and reliable mounting clamps makes it convenient to install and use.
- The performance of pressure adjustment is reliable with high precision.
- The efficiency of eliminating moisture and solid grain is high.
