What is a Combo FRL or Air Preparation Unit?
The “Air Preparation Units” designated above are often combined to create two- or three-piece units, either with pipe nipples in the case of the traditional designs, or by directly fastening to each other using screws and O-ring seals between components in the more modern “modular” design. A filter+regulator+lubricator combo is an FRL while a valve+integralFR+lubricator would be a VBL. (B is the Watts prefix for an integral filter-regulator.)
