Festo
The Festo part number 8175801 is an industrial filter regulator from the MS series, size 4, featuring a structural design with a directly controlled piston regulator, a pressure gauge displaying in MPa, and a rotary knob with detent for the actuator lock. Operating with compressed air conforming to ISO 8573-1:2010 [7:4:4] or inert gases, it provides a normal nominal flow rate of 1500 l/min, a 5 µm filtration grade, a 75% condensate separation degree, and a manual rotating condensate drain with a 16.5 ml max condensate volume. The unit delivers constant output pressure with secondary exhausting and return flow characteristics across an operating pressure of 0.1 MPa to 1 MPa (1 bar to 10 bar), a pressure regulation range of 0.3 bar to 7 bar, and a max pressure hysteresis of 0.05 MPa (0.5 bar / 7.25 psi) while maintaining a vertical ±5° mounting position, CRC 1 low corrosion stress, VDMA24364-B1/B2-L LABS conformity, and reduced Cu/Zn/Ni suitability for Li-ion battery production.
