Function
2.3.1
General
The roof-mounted fan in conjunction with the corresponding inlet
filter(s) is used to dissipate heat loss from enclosures and ventilate
the enclosure, thereby protecting temperature-sensitive compo-
nents.
This is achieved via the direct infeed of ambient air, the tempera-
ture of which must be lower than the admissible enclosure interior
temperature.
The ambient air enters the enclosure via an air inlet grille in the
lower section and is drawn upwards through the enclosure by the
roof-mounted fan. The warmed air is then returned to the outside
via the fan. It is not possible to change the air flow direction.
2.3.2
Safety devices
The fan is equipped with a thermal winding protection for protec-
tion against overload.
2.3.3
Filter mats
The roof-mounted fan is supplied with four pleated filters (class
ePM10 50% to ISO 16890) pre-installed. The filter must be
checked regularly depending on the level of dust exposure, and
replaced as necessary.
