Definitions

  • the invention relates to a clean room arrangement that provides an enclosure that is directly or indirectly adjacent to a floor area and separates a room from an environment. Furthermore, a mobile filter-fan unit is provided, which has an air inlet and an air outlet area and is arranged outside the room in the environment. The air outlet area of the mobile filter-fan unit is connected to the space delimited by the housing via a supply line.
  • Clean or ultra-clean room describes a room that is closed off from its surroundings and in which the concentration of airborne particles is kept as low as necessary, depending on the processes or activities to be carried out within the room. Clean rooms are preferably used in semiconductor production, in optics and laser technology, in the life sciences, in medical research and in aerospace technology, to name just a few areas of application.
  • Clean and ultra-clean rooms are usually complex and technically complex areas, which are usually accessed via different lock systems. Clean rooms are fed with specially assembled air-conditioning units that ensure that contaminants are immediately removed from the air. For this purpose, a correspondingly filtered displacement flow is introduced into the clean room, within which the purity of the air is to be ensured by means of a large air flow rate. All surfaces facing the clean room as well as objects located within the clean room are subject to clean room-specific requirements in order to avoid air pollution in the form of outgassing, particle release or similar processes that contaminate the clean room air. Since humans are usually the largest source of particle release, appropriate work clothing, special work equipment and tools help to maintain the clean room quality that is to be maintained within the clean room, which is defined in standardized clean room classes. Work clothes, hoods, shoe covers, etc. made from special lint-free materials are used for this purpose.
