S-Series roof fans for flat roofs
The S-series roof fans and exhaust vents are designed to be installed in
the ventilation shaft, onto a silencer or in or other horizontal surface.
Thus, they are also suitable for gently sloping roofs. The S-roof fans and
S-exhaust vents are used, for example, in blocks of flats and terraced
houses, when flat-specific ventilation is required. The S-series roof fan
can also be used for modifying an old natural ventilation system into a
mechanical one during renovation.
