DA 300 compressed air purge unit for HEIDENHAIN linear and rotary encodes
click here for more images HEIDENHAIN offers the DA 300 Compressed Air Unit for purifying and conditioning compressed air. It consists of two fi lter stages (fi ne fi lter and activated carbon fi lter), automatic condensation trap, and a pressure regulator with pressure gauge. The compressed air introduced directly onto the encoders must be cleaned by a microfilter. One DA300 can serve up to 10 encoders.
Its pressure gauge and automatic pressure switch (available as accessories) effectively monitor the DA 300. The required air flow is 7 to 10 l/min per linear encoder; permissible pressure is in the range of 0.6 to 105 to 1 · 105 Pa. The compressed air must fl ow through connecting pieces with integrated throttle.
