Description
The LFR-3/8-D-MIDI-KB from the Festo D series combines an on-off valve, filter regulator with pressure gauge and branch module in size Midi. With G3/8 at inlet and outlet and 2420 l/min standard nominal flow, it supplies downstream valves and actuators.
Benefits
- Filter grade 40 µm at 2420 l/min standard nominal flow, air quality class at outlet [7:8:4] to ISO 8573-1:2010
- Pressure regulation range 0.5 to 12 bar at 1 to 16 bar operating pressure, max. pressure hysteresis 0.35 bar
- Condensate drain manual rotary, bowl holds up to 43 ml condensate, bowl with metal guard
- Pre-assembled: on-off valve to switch the air supply on and off and branch module for an additional air take-off
- Rotary knob with latch secures the pressure setting
Applications
The unit is fitted at the inlet of machines and systems, before the air is distributed to valves and cylinders. The LFR-3/8-D-MIDI-KB requires mounting position vertical ± 5° and a medium temperature of -10 to 60 °C. Permitted media for the LFR-3/8-D-MIDI-KB are compressed air to ISO 8573-1:2010 [-:-:-] and inert gases.
