Choosing cleanroom equipment

• Air Shower
  Use it when

  Operators need to remove dust from their bodies and clothing before entering the clean area after gowning

  Check when choosing

  • Separate personnel and material entries where possible (gowning room and air shower for people, pass box for materials).
  • Both doors must not open at the same time: interlocks for airlocks leading to Grades A and B of a sterile-medicines facility, at least a visual and/or audible warning for airlocks leading to Grades C and D.
  • In sterile-medicines facilities, the final stage of an airlock must match, at rest, the grade of the room it leads to.
• Pass Box
  Use it when

  Small items have to pass through the wall into the clean area without a person entering

  Check when choosing

  • Decide whether the box must be flushed with filtered air to protect the higher-grade side.
  • The doors must not open at the same time (whether to use an interlock is a design choice).
  • Only items on an approved list, validated for the transfer process, go into Grades A and B.
• Clean Booth
  Use it when

  Only a specific work zone or bench, not the whole room, needs to be made locally clean with filtered air

  Check when choosing

  • Decide the required cleanliness and airflow pattern first (unidirectional airflow for Grade A sterile manufacture: 0.36–0.54m/s at the working position, guidance value).
  • The installation must allow filter integrity testing and airflow volume measurement (requalification items).
• Panels
  Use it when

  Walls, ceilings and partitions divide the clean area and keep out external contamination

  Check when choosing

  • Choose the panel material and thickness for the cleanliness grade and process of the space.
  • Seal panel joints and moulding connections, for example with silicone, to keep the enclosure airtight.
