Gas Supply Requirements - Baker Bugbox Ax Manual

The Workstation is double pole fused (Live and Neutral) for protection against over current draw.
The fuses fitted are based on the voltage range applicable, see Table 3 for details:
Voltage Range
220-240 Vac
100 Vac, 110-120 Vac

Gas Supply Requirements

The workstation gas supplies are located at the rear of the unit as shown in Figure 2.
For standard physiological environment operation of the workstation the input gas requirements
are:
Gas
Nitrogen
5% Hydrogen in
Nitrogen*
Table 4: Standard Gases
For the gas supply we recommend direct connections of the gas bottle regulator to ensure
minimal pressure drops and flow rate restrictions.
The gas regulator should provide a minimum supply pressure of 3 bar gauge. The maximum
supply pressure permissible is 5 bar gauge. A supply pressure greater than this will damage
internal components of the Bugbox Ax and will invalidate the warranty.
Only the above stated gases are to be used with the workstation. Failure to comply with this may
cause the product to become hazardous.
* - Recommended Hydrogen concentrations are compliant to BS EN ISO 10165:2010 (Classification
of Flammable Gasses). The use of Hydrogen concentrations up to a maximum of 10% in Nitrogen
(N ) is the responsibility of the user and must be assessed by the user in accordance to local
2
safety regulations at the installation location.
