FRL units are parts installed to prevent problems in air-pressure lines. The name FRL unit comes from the 3 items usually used in the set—an air filter (F), regulator (R) and lubricator (L).
H Series air treatment unit is similar with A series type. There is an up-gradation on the filter bottom. It equipped a connector on the drain port which can connect with a hose.
The HC combines a filter, a regulator and mist separator into one unit. The drain part of H series is a one-touch fitting structure.HC10/20 Series is with transparent bowl. HC30/40/50 bowl is covered with metal guard.
