Festo LFR-3/8-D-MIDI-KF Service Unit G3/8 40µm 2420L/min 16bar 185773

Overview
The Festo LFR-3/8-D-MIDI-KF (part number 185773) is a high-performance service unit from the LFR series, designed for comprehensive compressed air preparation in industrial automation systems. This Midi-sized unit combines a manual on/off valve, a filter regulator with pressure gauge, a distributor module, and a pressure switch into a single, integrated solution, simplifying system design and installation.

The unit features a 40 µm filter grade, effectively removing solid particles and contaminants from compressed air lines to protect downstream pneumatic components such as valves, cylinders, and actuators. The integrated pressure regulator is directly actuated via a diaphragm design, offering a pressure regulation range of 0.5 to 12 bar and an operating pressure range of 1 to 16 bar, ensuring precise and stable pressure control for a wide variety of applications.

With a maximum condensate volume of 43 ml and a manual rotary drain, the LFR-3/8-D-MIDI-KF allows for efficient and convenient condensate removal, helping to extend the service life of the entire pneumatic system. It delivers a normal nominal flow rate of 2,420 l/min, which is sufficient to supply multiple pneumatic devices simultaneously, and features two G3/8 threaded ports for easy inline installation. The unit is designed for vertical mounting (±5°) and can be installed in any position using through-holes, providing flexibility for diverse system layouts.

Key Features

• Integrated 4-in-1 Service Unit – Combines a manual on/off valve, filter regulator (with pressure gauge), distributor module, and pressure switch into a single, space-saving unit, simplifying system design and reducing component count.

• 40 µm High-Efficiency Filtration – Effectively removes solid particles and contaminants from compressed air, protecting sensitive downstream components such as valves, cylinders, and actuators from damage and wear.

• Precise Pressure Regulation – Directly actuated diaphragm-type regulator with a pressure regulation range of 0.5 to 12 bar and an operating pressure range of 1 to 16 bar, ensuring stable and accurate output pressure for consistent system performance.

• High Flow Capacity – Delivers a normal nominal flow rate of 2,420 l/min (normalised to DIN 1343), making it suitable for supplying multiple pneumatic devices simultaneously without significant pressure drop.

• Large Condensate Volume – 43 ml maximum condensate capacity with a manual rotary drain, allowing for efficient moisture separation and easy maintenance, helping to extend the service life of the entire pneumatic system.

• Robust Metal Construction – Die-cast zinc housing with a metal protection basket and PC clamps, providing excellent durability and corrosion resistance (CRC 2) for reliable operation in demanding industrial environments.

• Wide Operating Temperature Range – Rated for ambient and media temperatures from -10 °C to +60 °C, suitable for a broad range of industrial applications and environments.

• Integrated Pressure Gauge – Built-in pressure gauge provides immediate visual feedback of the regulated output pressure, simplifying system diagnostics and monitoring.

• Original Brand New, Within Warranty Period – Genuine Festo product, brand new in sealed packaging, covered by manufacturer's warranty.

• 100% Satisfaction Guarantee – Your purchase is protected by our satisfaction guarantee; return or exchange if not completely satisfied.
