Pneumatic filter regulator lubricator (FRL) is used to deliver clean air, at a fixed pressure, and lubricated (if needed) to ensure proper pneumatic component operation and increase their operation lifetime. Filters, regulators, and lubricators can be bought individually or as a package.
1. Filter: remove water, dirt and other harmful debris from an air system. This is often the first step in improving the air quality.
2. Regulator: adjust and control the air pressure of a system to ensure that down-line components do not exceed their maximum operating pressures. This is the second step in the FRL system.
3. Lubricator: reduce the internal friction in tools or equipment by releasing a controlled mist of oil into the compressed air. This is often done last and/or right before the component needing lubrication.
