30.7 Gas supplies
The air and oxygen high pressure gas supplies are
used as fresh gas.
30.7.1 Oxygen supply
The ventilator requires a supply of pure oxygen
between 2.8 to 6 bar
(Please refer to section 30.7.3 for further details).
30.7.2 Air supply
The ventilator requires a supply of medical grade
compressed air to ISO8573.1 Class 1.4.1 (minimum
level of filtration) between 2.8 to 6 bar
(Please refer to section 30.7.3 for further details).
Recommended level of filtration is class 1.1.1.
Description of Class 1.4.1
1= particle size of 0.1 microns. 4 = Pressure
dewpoint of +3ºC. 1= oil content 0.01Mg/m3
Description of Class 1.1.1
1= particle size of 0.1 microns. 1 = Pressure
dewpoint of -70ºC. 1= oil content 0.01Mg/m3
If the compressed air supply is found to fall below
the ISO8573.1 standard then in-line filtration of the
air is required.
30.7.3 Input pressures and ventilator
performance
30.7.3.1 Operation from 3.3 to 6 bar
The ventilator is factory set to operate with input
pressures of between 3.3 to 6 bar, this is to achieve
the maximum HFO performance.
30.7.3.2 Operation from 2.8 to 3.2 bar
If the ventilator is to be used with input pressures of
between 2.8 to 3.2 bar the input pressure regulators
need to be adjusted as per service manual
instructions. The user needs to be made aware that
once adjusted the ventilators upper end
performance will be curtailed. Details of the
performance changes are available in the service
manual. Note: The adjustment of the input pressure
regulators can only be carried out by trained service
engineers.
