Festo
531331
Filter regulator MS6N-LFR-3/8-D7-EUM-AS
The Festo 531331 is an MS-series size 6 filter regulator featuring a structural design with an integrated metal bowl guard, a manual rotating condensate drain with a 38 ml maximum volume, and a 40 µm grade of filtration achieving a 75% degree of condensate separation. It operates within a pressure range of 0.8 bar to 20 bar (0.08 MPa to 2 MPa), providing a pressure regulation range of 0.5 bar to 12 bar with constant output pressure, secondary exhausting, and a maximum pressure hysteresis of 0.25 bar (0.025 MPa / 3.625 psi). Designed for vertical installation within ±5° using compressed air per ISO 8573-1:2010 [-:4:-] or inert gases, this unit delivers a normal nominal flow rate of 4000 l/min and includes a pressure gauge alongside a rotary knob with detent actuator lock that can be closed with accessories.
