Combination Units

Norgren’s box sets pull together, in a simple ready to go assembly all the elements needed for an efficient compressed air system.

Correct compressed air preparation means using a filter regulator lubricator (FRL) in the correct order. Combination FRL assemblies or maintenance units allow your choice of units to be assembled. Norgren box sets are the ideal assembly - a filter/regulator, lubricator, shut-off valve, gauge and mounting brackets fully assembled.
