Festo
194840
Filter regulator LFRS-3/4-D-DI-MAXI-A
The Festo part number 194840 is a D-series Maxi filter regulator featuring an integrated rotary knob lock and a pressure gauge with a working pressure range of 1 to 16 bar and a pressure regulation range of 0.5 to 12 bar. Designed for a standard nominal flow rate of 6,800 l/min, this assembly includes a 40 µm filtration grade, a fully automatic condensate drain, a 43 cm3 maximum condensate volume, and a metal bowl guard for operation within an ambient and medium temperature range of 5 to 60 µC. It processes compressed air conforming to ISO 8573-1:2010 [7:9:-] or inert gases, maintains a maximum pressure hysteresis of 0.4 bar, exhibits a CRC rating of 2 for moderate corrosion stress, and requires a vertical assembly position within a plus or minus 5-degree tolerance.
