Definitions

  • a person in the area of the work opening can easily the clean air screen z. B. with their hands penetrate to z. B work on the product without that the shielding of the working opening by means of the clean air screen is adversely affected.
  • B. foreign substances adhering to the arms or hands of the person get into the clean air cabin and when handling the product to undesirable contamination of the product to lead.
  • the clean air screen shielding the working opening can be used for the known method z. B. in the area of the work surface Absorb parts of the clean air in the clean air cabin, so that a negative pressure in the area of the work surface arises.
  • the negative pressure leads to a deflection of the clean air screen.
  • the clean air screen can by the resulting Negative pressure be deflected so that edge areas of the clean air screen the product on the work surface flow around and thereby the product with beforehand from the environment contaminate ingested foreign substances.
