Product Overview
The FESTO LFR-D-O-MIDI (Part No. 162689) is a high-performance pneumatic filter regulator belonging to Festo’s renowned LFR series of service units. This combined unit integrates a centrifugal-type filter with a precision diaphragm pressure regulator in a single compact housing, designed to condition compressed air for downstream pneumatic control systems. The filter element removes condensate, oil aerosols, and particulate contamination, while the downstream regulator maintains a stable, adjustable output pressure independent of fluctuations in the supply line. Engineered for the MIDI size range, this unit is a direct-fit service component widely deployed in industrial automation, process control, and factory pneumatic networks where air quality and pressure consistency are critical to actuator and valve performance.
