Festo
537656
Air preparation unit FRC-1/4-DB-7-MINI-H
The Festo 537656 is a mini DB-series structural design filter regulator air line lubricator featuring an 88 mm width, a rotary knob with detent actuator lock, a semi-automatic condensate drain, and a 40 µm grade of filtration. This unit provides secondary exhausting and a return flow function, a pressure gauge, an operating pressure of 0.15 MPa to 1 MPa (1.5 bar to 10 bar), a pressure regulation range of 0.5 bar to 7 bar, and a standard nominal flow rate of 650 l/min. It operates on compressed air as per ISO 8573-1:2010 [-:-:-] or inert gas with a vertical +/- 5° mounting position, achieving an output air quality class of ISO 8573-1:2010 [7:8:-].
