Note:

The Fabius GS Premium is equipped with S-ORC (Sensitive Oxygen Ratio Controller)

S-ORC is a control element which provides a minimum O₂ concentration in the fresh gas flow. From a flow rate of approx. 300 mL/min, the N₂O concentration in the fresh gas can be set between 0 and 75 %.During O₂ shortage S-ORC limits the N₂O concentration in the fresh gas, so that the O₂ concentration does not drop below 21 vol. %.S-ORC prevents N₂O flow if the N₂O metering valve is open and O₂ metering valve closed or if the O₂ flow is less than 0.2 L/min.

Note:

The flow reading is obtained at the middle of the floating ball.
