Structure and Function
SMART-N radial roof fans are of original construction of bent steel profiles, making up a ske-
leton of streamline and robust properties.
Inside is located a motor with a radial impeller. Impeller is statically and dynamically balanced
according to ISO 14694:2003+AMD1:2010 gaining the
G 2,5
class
.
Lower skeletons (
of the 3000 r.p.m synchronous rotation fans)
are surrounded with a circumfe-
rential wire net, providing an openwork structure, through which the air is discharged (see Fig.
No.2). In
case of the other fan types,
their
lower skeleton is of steel
rods (see Fig. No.1). Upper
parts of the fan are shielded by a plastic hood.
The fan has to
be mounted on a roof base. It is recommended to apply a sound absorbing roof
base
TPD-N
or
TPDC-N
of suitable size, adapted to the given fan.
