1. RY-IIB

2. O2 supply range: Rated working pressure: 0.4Mpa, allowable rang: 0.27??0.55Mpa, from central supply or gas cylinder

3. Adjusting range of flow: O2: 0.1??10L/min, N2O: 0.1-10L/min

4. O2: Flush: 35-75L/min

5. Breathing circuit: Working mode: Closed, semi-closed 1??4kpa, semi-opened, the resistances of inspiration and expiration are all not more than 0.6kpa, CO2 absorb cylinder: 2 piecs, can load with 1600g Na2CO3 at one time.

6. Alarm for O2 supply failure and N2O automatic cut-off device: Audible alarm will be given for at least 7s when O2 supply pressure drops below 0.2Mpa, gas cut-off device makes the flow of N2Ostop before that of O2 supply pressure is lower than alarm pressure and is still falling.

7. Evaporator: Concentration: 0??5vol%, temperature: 15??35flow: 0.25-15L/min, with flow, and pressure compensated auto, and can select enflureance or isoflureance according to users needs.

8. Dimension of Anaesthetic machine: (490*450*1320)mm

9. Weight: 30kg
