Product Overview
The FESTO LFRS-D-MIDI-A (Part No. 194757) is a high-performance pneumatic filter regulator belonging to FESTO’s renowned D-series air preparation family. This combined unit integrates a centrifugal-type filter with a precision diaphragm pressure regulator in a single compact housing, delivering clean, dry, and accurately regulated compressed air to downstream pneumatic actuators, valves, and control systems. Designed for MIDI-size (G1/4 to G1/2) service, the LFRS-D-MIDI-A features a manual rotary knob with lockable adjustment, a condensate drain, and a high-efficiency filter element that removes solid particles and liquid water droplets from the air stream. As a core component of any industrial pneumatic infrastructure, it ensures stable secondary pressure regardless of fluctuations in the primary supply, protecting sensitive equipment and maximizing process repeatability.
