The NL2 series is Aventics' compact air preparation module — filters, regulators, lubricators, and combined FRL assemblies in a small footprint for moderate-flow point-of-use air conditioning. G1/8 and G1/4 port options pair with a range of filter element ratings, regulator pressure ranges, and manual or semi-automatic drain configurations. The NL2 platform handles workstation, panel, and machine-subsystem air preparation where shelf space and unit cost both matter.
