FRLs are single unit assemblies comprising a filter, regulator and lubricator for regulating air pressure, filtering out contaminants and lubricating compressed air to reduce friction in compressed air systems. These ARO pump FRLs feature bowls made of metal / metal with sight glass / polycarbonate for ensuring excellent thermal insulation and resistance against UV radiations. These ARO pump FRLs have a maximum flow rate of 215 cfm and are offered in heights of 6.2, 8.21, 9.91, 11 and 13.6 inches.
