        have the clean air blown into the cleanliness-sensitive room via individual flow tubes. This
        would lead to undesired turbulent air conditions. Instead, the air is discharged evenly
        over the entire ceiling surface. This initially creates a low-turbulence air distribution that
        flows off the ceiling in a directed manner.

        Another significant innovation is the use of side walls that are open over their entire
        surface in terms of flow technology, which creates a very low-turbulence, directed flow
        pattern from the ceiling, across the cleanliness-critical products, towards the outer
        walls. This innovation and scientifically proven flow conditions make it possible to realise
        low-turbulence, directional flow patterns, which are considered a prerequisite for the
        highest cleanliness requirements, without having to use a very cost-intensive raised
        floor system.
        For further optimisation of the flow conditions (see figure 2, righ side), a raised floor can
        be integrated as an option. In this variant, the unclean ambient air is drawn in by means
        of an FFU, in which the air is then processed and cleaned. The cleaned air is introduced
        into the pressure plenum above by means of riser hoses. The air is discharged from
        the ceiling area very homogeneously over the entire ceiling surface with the aid of a
        pressure plenum. In this variant, too, the cleaned air is discharged via the side walls and,
        depending on the design variant, additionally via an optional raised floor.

                                                                                                 CAPE –

        Figure 3; Large-scale system (> 200 sqm floor area, 7 m cleanroom height) of the
        air cleanliness ISO class 5. Left side: concept sketch. Right side: set-up phase of the
        system with textile pressure plenum already in place.

        Systems based on this conceptual variant have already been developed and realised
        for larger areas of more than 200 square metres usable cleanroom floor space of ISO
        class 5 (see figure 3). These cleanroom areas are created as self-supporting systems,
        in which the entire usable area is realised without any disturbing mechanical supports
        in the central area. These large systems are made up of individual modules and can be
        expanded or reduced at any time in any combination. The installation of this system,
        including commissioning, is completed within one working day. The system‘s key values
        are as follows:

        Cleanroom provided and media supply
        f   Provided cleanroom of ISO air cleanliness class 5
        f   media supply: 5 x 230 V; internal LED-lighting
        f   4 x 3 FFUs with an overall air volume of 9.000 m3/h; air intake on front side
        f   air distribution fabrics are opened downwards; additional ceiling openings for lifting
        Cleannroom dimensions
        f   dimemsions: 14m x 14m; clearance per module: 6,5m x 7,5m
        f   maximum height: 6,6m; insertion opening: 5,0m x 4,5m
