Device and method for diffusing a protective flux. In order to protect one area of a service station, a more or less parallel air flow is created in the direction of the area. Above a threshold F, the air flow has a gradually increasing speed Vand, below the threshold, the air flow speed Vis more or less uniform along the length of a flow section in a plane P which is transverse to the direction of flow D. One possible configuration for an air flow diffusion device, which allows a confinement barrier to be created, consists of a diffusing wall comprising a main wall and a lateral wall. The main planar wall is adapted to diffuse a main laminar flow in the sterile area to be protected. The lateral wall is adapted to diffuse a lateral flow divergent from the main flow. A skirt is disposed to create an obstacle to the lateral flow and to accelerate the flow by of deflection.

Method and device for diffusing a protective flux with regard to a surrounding environment

An installation includes a worktop, a first wall and a device for the close protection of products arranged on the worktop, whereby the products are sensitive to contamination from the ambient environment. The products are protected by diffusion of a sterile air stream in a direction substantially perpendicular or parallel to the worktop. The device extends along the worktop and has a least one end adjoining the first wall so that there is an air gap between the end and the first wall. The end is formed by a porous second wall made of perforated material, extending substantially perpendicular to a longitudinal axis of the device, in such a way as to create in the gap a sterile air leakage directed outward away from the worktop, whereby the sterile air leakage counters any ambient air induction into the gap toward the worktop.
