摘要

The device has ventilators in housings, which are supplied with circulating air from pref. a clean room, via a recycling channel. Part of the air is directly supplied to the ventilator (3) while bypassing the recycling channel (4,5). The supply passes over a guide element, which together with the housing defines an air flow channel. A mixing zone is located in front the channel. An intake hose (7) connected to the housing pref. opens into a ceiling (6) of the clean room (1) and/or an intake area of the ventilator (3). The device also has a filter.
