Instrument air filtration system to be set up in line with 4.1.4 of Article devices connected 1,2,3,5 air supply equipment, piping, valves and fittings shall comply with the provisions of this Regulation 4.1.5 instrument air supply Source control systems, monitoring and alarm, hospitals centralized gas supply, should be consistent with the instrument air supply provisions of Article 4.1.6 of the specification should be set independently set emergency backup power equipment for medical compressed air impacts: (1) The output pressure is too high or too low. Ventilator by the electronic control section and the control section composed of gas path, compressed air, such ventilator requires external compressed air and oxygen gas source, the ventilator air pressure when the requirements in 0.3 ~ 0.67MPa. If the output pressure is too high or too low, the supply of medical centers, ranging from the impact the output of the gas concentration of the mixture, namely the output of the oxygen concentration ventilator; weight will directly affect the working pressure, resulting in failure of the ventilator.
