Product Overview
The AVENTICS 0821300353 pneumatic filter regulator, designated NL4-FRE-G012-GAU-100-PNB-AO-05.00, is a combined air preparation unit that integrates filtration and precision pressure regulation within a single modular housing. Manufactured by AVENTICS (Emerson), this unit conditions compressed air by removing particulate contamination and condensate while maintaining a stable downstream working pressure regardless of fluctuations in inlet pressure or flow demand. As a process and pneumatic valve assembly, it serves as a critical control element in industrial air networks, protecting downstream directional valves, proportional valves, cylinders, and actuators from contamination and pressure instability. The NL4 series platform is engineered for modular integration with compatible AVENTICS air preparation components, enabling flexible system configuration in automated production environments.
