SMC Corporation AW40N04EZ Air Pressure Regulator

Description:

The SMC AW40N04EZ Regulator is an industrial air pressure regulator used in compressed air systems to maintain stable downstream pressure for pneumatic equipment and automation systems. Commonly installed in factory automation panels, air preparation units, packaging machines, and manufacturing systems where precise and consistent air pressure control is required. Maintenance teams and system integrators use this regulator for pneumatic system setup, replacement of failed regulators, and upgrades to air control assemblies.

Applications:

The SMC AW40N04EZ Regulator is commonly used in pneumatic control systems, assembly machines, packaging equipment, conveyor systems, and industrial automation lines where stable air pressure regulation is required for actuators, valves, and air-driven tools. It is typically part of an FRL (Filter-Regulator-Lubricator) system and ensures consistent operating pressure in continuous-duty industrial environments.
