MED & dMED: precision in critical environments

Ambient air pollution can play havoc with the medical air your staff and patients need. Atlas Copco's MED/dMED systems convert compressed air into highly-purified air for all your medical applications.

The MED, four-stage filtration

MED 13

The MED series ensures high quality air in worst case, but real-life pollution scenarios. The MED works with a four step filtration process:

  1. A WSD water separator, a DD and a PD coalescing filter remove free water and particles down to 0.01 micron and eliminate oil droplets down to 0.01 ppm.
  2. A heatless desiccant dryer reduces moisture content to a pressure dew point of -40°C/-40°F, removing any risk of condensation, bacteria and mold growth.
  3. A dual cleaning stage includes activated carbon to eliminate hydrocarbons (oil vapor and smells). A catalyst then converts CO into CO2.
  4. A particle PDp filter at the exit removes particles that may have been introduced in the desiccant stages down to 0.01 micron.

The dMED, seven-step filtration

dMED 35

The dMED (dual MED) is a duplexed purification package for converting a compressed air source into breathing quality air. You dMED package is independently certified to provide medical air in compliance with the European Pharmacopoeia.

The dMED has 7 stages of active purification:

  1. A water separator to remove liquid water
  2. A bulk aerosol filter eliminates oil and water
  3. A fine coalescing filter removes even smaller particles of oil and water
  4. A desiccant dryer takes out any remaining water and CO2
  5. Activated carbon removes gaseous impurities
  6. A catalyst takes care of a CO oxidation
  7. A bacteria filter eliminates bacteria and fine particles. This bacteria filter is an Atlas Copco PDp filter, which has been externally tested and certified as a bacterial filter. 

Full compliance

Compressor Technique - certificate ISO 9001 - 2000

You MED or dMEd comes pre-certified to simplify the certification process on installation. They are designed and manufactured according to:

  • ISO 9001
  • ISO 14001
  • ISO 13485:2003 quality management system

The MED systems also meet and exceed the requirements of the most demanding standards and regulation in the medical industry, such as:

  • Medical Device Directive MDD93/42/EEC
  • European pharmacopoeia
  • EN ISO 7396-1
  • ISO 14971
  • Health Technical Memorandums HTM 02-01 and HTM 2022 for medical systems
