18.06.2020
STRUCTURE AND FUNCTION
SMART-SN
roof fans have a multi-spoke steel frame, which creates a streamlined and very mechanically
durable housing, covered from below with an openwork protective cover preventing access to the interior of the
fan, meeting the
ISO-13857
standard – see below – Picture 1 and Picture 3.
Inside the housing is a flange motor with a radial impeller mounted directly on the shaft, which is statically and
dynamically balanced in accordance with
ISO 14694
, obtaining class
G 2.5
. Each
SMART-SN
fan is equipped
with an inlet with a round flange with holes, which allows the fan to be mounted with threaded fasteners – see
below – Picture 2 and Table 3. The top side of the fans is protected by a plastic cover from the weather conditions.
