Test sections for air tight welds during fabrication

final stage is to powder coat.


Pressure rating:

The discharge pressure of the oxygen generator is 100 kPa (14.5 psi).
oxygen concentrator output pressure is 11.6 psi (80kpa).

Cause the oxygen is pumped into chamber inside and chamber inside pressure is 50kpa/60kpa (8.7psi), in case of backflow, oxygen concentrator output pressure must higher than chamber pressure.

 Philips output pressure only 5.5psi.
