Work station for performing e.g. fractionation operation, has blower unit generating frontal air flow, and another blower unit generating air flow from and at proximity of opening in direction of manipulation zone

摘要

The work station has a blower unit (4a) that generates a frontal air flow, which is vertical, for constituting a frontal protection screen for an operator. A blower unit (4b) generates an air flow from and at proximity of an opening (3) in a direction of a manipulation zone (9). The frontal air flow generated by the unit (4a) converges towards the interior of an enclosure that is driven by the air flow generated by the unit (4b). The unit (4b) is placed at the level of an upper position of the opening and the unit (4a) is placed at the level of a bottom position of the opening.
