What is a FR + L (Filter Regulator + Lubricator)?
Filters are mounted in the air line upstream of regulators, lubricators, directional control valves and air driven devices such as cylinders and air motors. Filters eliminate contaminants from pneumatic systems, avoiding damage to equipment and decreasing production losses due to contaminant-related downtime.
Pressure regulators are used to regulate pressure to: blow guns, air tools, blow guns, air gauging equipment, air motors, air cylinders, and fluidic systems, spraying devices and most other fluid power applications.
Lubricators are sized by downstream flow necessities. An analysis of air flow use must be made. After determining how much air flow is needed, a lubricator can be chosen.
