Festo LFR-1/8-D-MINI Filter Regulator G1/8 40µm 750L/min 12bar

Overview
The Festo LFR-1/8-D-MINI (part number 159630) is a compact, high‑performance filter regulator from the LFR‑D series, designed for compressed air preparation in pneumatic systems. Combining a 40 µm particulate filter and a precision pressure regulator in a single unit, it ensures clean, reliably controlled compressed air for sensitive pneumatic equipment.

The regulator features a G1/8 port connection, a standard nominal flow rate of 720 l/min (or 750 l/min), and a pressure regulation range of 0.5 bar to 12 bar. The integrated pressure gauge allows for immediate visual monitoring, and the rotary knob with lock secures the set pressure value to prevent unauthorised adjustment.

Built from a durable die‑cast zinc housing and a polycarbonate bowl with a metal bowl guard, the unit offers high resistance to moisture and corrosion (CRC 2). The manual condensate drain enables efficient removal of accumulated condensate, and the vertical mounting position (± 5°) is easy to integrate into control cabinets and machine panels. With an ambient temperature range of –10 °C to +60 °C and compliance with ISO 8573‑1 and RoHS, the LFR-1/8-D-MINI is a dependable choice for reliable air preparation in industrial automation.

Key Features

• 2‑in‑1 Functionality – 40 µm filtration and precise pressure regulation in a compact, space‑saving unit, eliminating the need for separate components.

• High Flow Rate – Delivers 720 l/min (normalised to DIN 1343) or 750 l/min standard nominal flow rate, ensuring efficient operation of downstream pneumatic equipment.

• Precise Pressure Control – Pressure regulation range of 0.5 bar to 12 bar with a max. pressure hysteresis of 0.2 bar for stable output pressure.

• Secure Setting Lock – Rotary knob with detent locking mechanism protects the adjusted pressure value from unauthorised or accidental changes.

• Durable Construction – Die‑cast zinc housing and polycarbonate bowl with metal bowl guard offer excellent corrosion resistance (CRC 2) and robustness for demanding environments.

• Easy Maintenance – Manual condensate drain with metal bowl guard allows quick removal of accumulated condensate without disassembly.

• Integrated Pressure Gauge – Built‑in pressure gauge for immediate visual feedback of the regulated output pressure, simplifying system diagnostics.

• Proven Quality – Compliant with ISO 8573‑1 and RoHS; the unit is pre‑assembled and factory‑tested, ensuring reliable, ready‑to‑use operation.

• 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.
