2 General description
2.1 Introduction
Description
High quality air is of vital importance to many industries, but nowhere as literally as in the medical sector.
The purity of the compressed air for certain hospital applications is crucial. The air drawn from our
environment however, especially in cities or industrial areas, is rarely of a sufficient quality for medical
purposes.
For this application, BeaconMedæs has designed the dual medical air purifier range (dMED 7 up to dMED
145). The dMED takes air from any regular compressor and treats it to become ultra clean. It consists of a
number of components, which together, after the commissioning certification, produce air with a quality
matching the Pharmacopoeia legislation.
The dMED is primarily aimed at the health care sector where applications like breathing air in operating
theatres and surgical air to drive surgical tools demand high quality air.
A dMED consists of 2 independent air treatment units, each consisting of following stages of cleaning:
• A water separator (WSD) to eliminate free water from the compressed air, thus ensuring good operation
of the desiccant dryer.
• Two coalescing filters (DD filter and PD filter) to remove contaminating particles and oil droplets.
• A desiccant dryer (CD dryer) to lower the pressure dew point (PDP) to -40 ˚C (-40 ˚F), eliminating the
risk of condensation and strongly reducing water-related problems like bacteria growth.
• The QDT+ filter reduces hydrocarbons like oil vapour and smells to harmless levels and converts excessive
concentrations of CO into CO
2
.
• A particle filter (PDp filter) to eliminate particles that may have migrated out of the desiccant dryer.
Both units are controlled by a central controller (ES-MED). This central controller activates one unit and will
switch to the other one after a certain amount of time has elapsed. This guarantees a constant delivery of
purified air and also ensures service can be performed on one unit whilst the system is still operating. At all
times an indication of dew point and pressure can be retrieved from the display.
Key qualities
• Pharmacopoeia compliant:
The European Pharmacopoeia legislation accurately defines the required quality for breathing air in
hospitals, medical theatres and ambulatory centres. BeaconMedæs has adopted this quality level for the
dMED range and was certified by an external authority.
• Company certification according to EN ISO 13485:
Hospital equipment with an influence on patient health must be certified to the Medical Devices Directive
(MDD 93/42/CE). This requires that the manufacturer is certified according to EN ISO 13485 and
organises strict product follow-up once in the field.
