The gas-mixing unit serves as proportioning device for medical gases
(e.g. oxygen, nitrous oxide and compressed air).The desired gases can be
mixed in any relation by means of the proportioning valves below the
flowmeter tubes. The types of gas can be clearly recognized on the
control knobs.
To prevent confusion, the control knob of the regulating valve for oxygen
differs haptically from the two other valves. Inadvertent shift of the
settings is avoided by a special twisting-prevention device.
The proportioning valves (control knobs) permit a continuous flow, when
they are rotated counterclockwise. The measuring area for O
two flowmeter tubes, so that an exact proportioning is guaranteed.
