BOA-IIIB3 consists of trolley, supply system, breathing circle system, ZFG-B1 vaporizer, pipelines and accessories
The frame is designed as a trolley with handles on the back. There are drawer and pan near the bottom for deposit. Two stainless plates on the back of drawer are for 10L aluminum alloy cylinders, which can be fixed by straps on the back of the base (Shown as Figure 24). Four castors under the trolley are easy to operate, two of which are lockable.
- Supply System
This machine applies three kinds of air source, O2, N2O and Air. O2 and N2O are supplied by steel cylinder or by central pipeline system. And Air is supplied by medical air compressor or by central pipeline system. The supplied gas from cylinder should be compressed to 0.4-0.5MPa through relief valve before entering O2 and N2O Hose. The Hose is connected with the inlet connector at the back left of the supply system (Shown as Fig. 2). Be sure that the gas name marked on the connector is the same as the gas from the cylinder. The supplied gas from central pipeline system can enter the hose directly, while the attention is the same. The working principle of air supply system is shown as Fig 3a:
- Pressure gauge (1) shows pressure in the cylinder. Relief valve (2) compressed the gas from the cylinder to 0.4-0.5MPa. Check valve (3) can prevent from gas mixing. And source pressure gauge (4) at the front right of the machine monitors the input gas source pressure (shown as Fig.3).
