With the laminar flow box of the FBS series a portable clean room workspace is created which, depending on the model, can measure between 0.24 to 1.12 m2. It is used for the manufacture of products and for the storage of objects in clean room conditions.Ambient air is drawn in using EC fans and pushed through the filter. This generates an ISO class 5 laminar flow, i.e. the air streams down in parallel flow lines. Particles are picked up the flow of air and transported out of the box through the perforated floor.
