Gray Area

The gray area is the interim space between the surroundigs and the white area. The pressure cascade ensures that contamination is limited and that no exterior air enters the white area. The service area is located in the gray area i.e.changing rooms and the servicing and repair of technical systems. The white and gray areas are separated by a wall or a curtain.
