Product Information MG 25 capacity range up to approx. 22 Nm 3 /h. MG 45 capacity range up to approx. 46 Nm 3 /h. MG 75 capacity range up to approx. 68 Nm 3 /h. MG 95 capacity range up to approx. 90 Nm 3 /h. MG 125 capacity range up to approx. 135 Nm 3 /h. For the exact pressure and flow capacity ratios, please see the technical data overleaf. Benefits high mixing accuracy avoids the need to stock multiple pre-mixes (cost saving) does not require receiver (cost and space saving) inlet gas filters protect the device against impurities pneumatic operating principle, no electrical connections required mixed gas production from 2 l/min to the max. flow robust, compact design panel for wall mounting minimal maintenance required Easy operation blends are factory set and tamper proof (FIX) a mixing valve with a control knob and %-scale provides infinitely variable mixture settings (FLEX) High process reliability independent of pressure fluctuations in the gas supply independent of withdrawal fluctuations (in permitted range) fail safe design (unit shuts down on failure of either gas supply) lockable to prevent tampering (FLEX) Options monitoring of the gas supply by means of pressure switches; a low inlet pressure triggers a visual alarm (audible optional) and switches a potential free contact (e.g. to shut down machinery to avoid quality problems) - electrical connections required Other models, options and accessories available on request.
