Abstract (en)
[origin: EP0867665A2] The clean air cabin is equipped with a feed installation for additional clean air producing a clean air cushion directly over the work surface (10) of the work plate (9). The work plate is sieve-shaped. The area of the lower surface (11) of the work plate turned away from the work surface is formed as a trough component (8) sealed against the atmosphere and in it issues at lease one conduit (19,19') feeding clean air. In at least one edge area of the work plate at least one conduit feeding clean air is arranged, which in specific sections has outflow apertures, which steer the emerging clean air against a product on the work surface. In the area of the work plate on at least one clean air cabin wall at least one upwardly directed nozzle (33) is arranged.
