Description; Technical Specification - Parker BAC-4015 Mode D'emploi

2 Description

The Parker domnick hunter BAC-4015 is a fully portable pneumatically controlled air purification system designed to provide breathing quality
air to a higher level than specified in EN12021 for oil mist, vapour, odour and particulate removal. The BAC-4015 will also remove carbon
monoxide (CO) and reduce carbon dioxide (CO2) to fully meet EN12021 and other international specifications.
The BAC-4015 breathing air purifier utilises 5 separate stages of compressed air treatment, combined together in a compact and robust
housing.
1st Stage - Grade AA - high efficiency coalescing filter for removal of oil/water aerosols and dirt particulate down to 0.01 micrometre, giving a
maximum remaining oil content of 0.01 mg/m
2nd Stage - Grade AC - adsorption bed of activated carbon for removal of oil vapours and odours. The downstream air after this stage now has
a maximum remaining oil content of 0.003 mg/m
3rd Stage - Adsorption Purifier regenerative adsorption bed of desiccant for removing water vapour and also reducing the CO2 content prior to
the catalyst stage. The desiccant purifier maintains a low dewpoint by utilising the heatless pressure swing adsorption principle. Cycle time is
controlled by a pneumatic cam timer.
4th Stage - Grade HC - catalytic element for removal of carbon monoxide by oxidation to carbon dioxide through chemisorption and catalysis.
The catalyst is kept active by maintaining a low dewpoint prior to the catalytic bed. This is achieved by the integral adsorption purifier (stage 3).
5th Stage - Grade AA - high efficiency coalescing filter for removal of oil/water aerosols and dirt particulate down to 0.01 micrometre, giving a
maximum remaining oil content of 0.01 mg/m
These air purification stages are installed in an epoxy painted steel cabinet with lifting handles and a lockable door. Inlet and outlet pressure
gauges are mounted on the upper facia panel. The outlet pressure can be set as desired using the pressure regulator.
