Industrial NAC4000-N04DG-3 Combo Modular Device

SMC NAC4000-N04DG-3 is a compact, all-in-one FRL combo modular device from the NAC4000 series that integrates a filter, regulator, and lubricator in a single housing. It conditions compressed air for downstream pneumatic components by removing particulates, regulating pressure, and delivering lubrication to downstream cylinders and valves. The N04DG variant is configured for 1/2 in NPT threaded connections, enabling straightforward integration into modular air-prep circuits and compatibility with other NAC4000 family modules. Designed for automation environments, it finds use in manufacturing, packaging lines, and assembly cells where reliable air preparation and consistent downstream performance are essential. The FRL combo approach consolidates three essential functions into one compact unit, reducing the number of fittings and potential leak points in the supply line and simplifying installation and maintenance in tight control panels and routed manifolds. This makes it a practical choice for engineers seeking a streamlined, space-efficient solution to condition and standardize compressed air before actuators, valves, and other pneumatic devices.
