A conversion to a recirculation system is also indicated if an open fireplace is to be operated in the space of the extractor hood.

  • the maximum outflow cross section is available and the exiting filtered vapor has a low flow velocity. If a certain outlet direction of the filtered Wrasens is to be defined, one or more of the Partial surfaces are closed. The flow rate of the exiting filtered vapor is then higher. Due to the at least two partial surfaces twisted relative to one another, this adjustment of the outlet direction can still take place even when the filter housing is already mounted.
