Product Description
Rexroth 3723522220
The Rexroth 3723522220, also known by its Aventics part number within the NL2-FRE series, is a high-performance filter regulator designed for robust air preparation in pneumatic systems. This unit efficiently combines air filtration and pressure regulation into a single, compact component. It removes particulate contaminants and condensed water from compressed air down to a 40 µm filtration level and provides a stable, adjustable output pressure between 0.5 and 10 bar. Ideal for industrial applications, the NL2-FRE helps protect downstream pneumatic devices, improve system efficiency, and ensure consistent operational performance.
