Anesthesia Machine

AR-322 Anesthesia Machine

Main body  

High-strength engineering plastic rack, light, beautiful and corrosion resistant

Scope of application

adult, child

Gas source

O2: 0.27--0.55MPa  N2O: 0.27--0.55MPa

Flow meter

O2: 0.1--10L/min   N2O: 0.1--10L/min

O2, N2O linkage and N2O Stopper

When using nitrous oxide, oxygen concentration>25%;

When the oxygen pressure < 0.2 MPa, the flow of nitrous oxide would be cut off.

Flow rate of rapid oxygen supply


Low oxygen pressure alarm

There will be sound alarm when the oxygen pressure < 0.2MPa


It has the function of automatic compensation based on pressure, temperature, and flow rate. The regulation range of evaporator concentration is 0--5vol%. Among Halothane, Enflurane, Isoflurane and Sevoflurane, one can be chosen for application as required by the customer. And vaporizers that are imported with original packaging are also available.

Respiratory circuit
