Hospital and Medical
A medical air supply is regarded as a vital part
of every hospital infrastructure and is one of
the few medicines that is manufactured onsite.
Compressed air can be used for a wide
variety of applications such as anaesthetics,
lung ventilation, intensive therapy, pneumatic
surgery tools, nebulisors and many more,
where the quality of the air is vitally important.
Parker domnick hunter BA-DME and BAM
breathing air purifiers provide integrated
filtration and adsorption stages to deliver the
air quality required for medical applications.
Parker domnick hunter purifiers have been
independently tested to the European
Pharmacopoeia Medical Air Standard.
The Parker domnick hunter BA-DME and BAM ranges comply
with the European Pharmacopoeia medical air standard

The BA-DME and BAM packages consist of several stages of
contaminant removal. Inlet filtration combines to remove
bulk water, particles and oil. The use of adsorption
materials, namely activated desiccant and carbon removes
water vapour and oil vapour/odours respectively. The
desiccant material is contained in a pressure swing
adsorption dryer that delivers a constant pressure dewpoint
of -40°C (-40°F).
Downstream of the desiccant dryer, a catalyst converts
carbon monoxide to carbon dioxide by catalytic conversion.
A final dust filter captures any particulates carried over from
the adsorption materials.
