The Rexroth R422100623 is a high-performance maintenance unit from the AVENTICS AS3-FRE series, designed for comprehensive compressed air preparation. This combination unit integrates a filter, regulator, and lubricator (FRL) into a single, compact assembly. It effectively removes contaminants, provides precise pressure regulation, and introduces a fine oil mist to lubricate downstream pneumatic components, ensuring system reliability and extending the service life of your equipment. Equipped with a pressure gauge for easy monitoring and a semi-automatic condensate drain, this unit is ideal for demanding industrial applications requiring clean, controlled, and lubricated compressed air.
