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).
HI unit’s pressure gauges are embedded into the valve body for saving the space.
The HIC combines a filter, a regulator and mist separator into one unit. The drain part of H series is a one-touch fitting structure. Built in pressure meter.
