FRL combines a filter, regulator, and lubricator into one assembly to keep your air compressor system in top working order. FRL has three main components: air filter, pressure regulator, and lubricator.

    Air filter regulators clean compressed air. It filters the air, captures solid particles (dust, dirt, rust), and separates any liquids (water, oil) from the compressed air. Filters are installed in the upstream piping of regulators, lubricators, directional control valves, and pneumatic devices such as air cylinders and air motors. Because air filters remove contaminants from pneumatic systems, they prevent equipment damage and reduce production losses due to contamination-related downtime. Downtime is expensive and often the result of contaminated and poorly maintained compressed air systems.

    The proper filter size should be selected for any application by determining the maximum allowable pressure drop the filter can cause. The pressure drop can be determined by referring to the flow curve provided by the manufacturer.

    General-purpose filters are used to remove water and particles while coalescing filters are used to remove oil, and vapor removal filters are used to remove oil vapors and odors.

    Pressure regulators reduce and control air pressure in compressed air systems, including screw air compressors. Regulators are also often referred to as PRVs (Pressure Reducing Valves).

    Ideally, a pressure regulator maintains a constant output pressure regardless of changes in input pressure and downstream flow requirements. In practice, the output pressure is affected by changes in primary pressure and flow.

    Lubricators add controlled amounts of tool oil to a compressed air system to reduce friction in moving parts. Most air tools, cylinders, valves, air motors, and other pneumatic equipment require lubrication to prolong their life.

    Using a pneumatic lubricator can solve the problem of too much or too little lubrication with traditional lubrication methods such as a grease gun or oil. Aviation lubricators also provide suitable lubricants for the tools used.
