Product Overview
The FESTO LFR-D-7-O-MIDI-A is a high-precision pneumatic filter regulator from Festo’s renowned LFR series (Filter Regulator combination), engineered to deliver clean, filtered, and precisely regulated compressed air to downstream pneumatic components. This MIDI-size service unit combines a centrifugal/coalescing filter element with a diaphragm-type pressure regulating valve in a single compact housing, removing condensate, particulate contamination, and oil aerosols while maintaining a stable secondary pressure independent of upstream fluctuations. As a core component of Festo’s modular air preparation system, the LFR-D-7-O-MIDI-A plays a critical role in protecting solenoid valves, cylinders, and proportional pneumatic devices from contamination and pressure instability in demanding industrial automation environments.

Engineering Features & Advantages
- Precision Performance: The diaphragm-controlled regulating valve maintains a constant output pressure with minimal hysteresis, ensuring stable actuation of downstream pneumatic valves, cylinders, and air motors even under fluctuating supply conditions.
- Integrated Filtration & Regulation: Combining a high-efficiency filter element with a precision regulator in one MIDI-size housing reduces installation footprint, piping complexity, and potential leak points within the air preparation circuit.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust die-cast housing and corrosion-resistant internal components suitable for high-cycle automation environments.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Festo LFR series service units, allowing drop-in replacement without modification to existing modular air preparation assemblies.
- Modular System Integration: Fully compatible with Festo’s modular connection system, enabling seamless combination with lubricators, soft-start valves, and shut-off valves in a single manifold-mounted unit.
Typical Industrial Applications
The FESTO LFR-D-7-O-MIDI-A is widely deployed in pneumatic control systems across heavy industry, including plastic injection molding machines requiring stable pilot air for proportional valves, metallurgical presses and forming equipment with high-cycle pneumatic
