Roof fan
max. 0,3 g/m3, max. 27 500 m3/h | SMART series KLIMAWENT

Application
The roof fans of new generation are designed for the general ventilation of buildings. They are meant for forwarding the dry
air of maximum temperature +60°C, of dustiness not exceeding 0,3 g/m³, without viscous, aggressive pollutants or impurities
that could create explosion risk. The SMART family of fans is a series of seven sizes of motor rates from 0,37 kW up to 7,5 kW
and maximum volume fl ow 27.500 m³/h.

Structure
The SMART fans as unique among the examples on the market are featured by original construction of bent steel profi les giv-
ing the skeleton of aerodynamic and at the same very robust properties. Inside is a motor with a radial impeller of aluminium
and steel sheets. The impeller is statically and dynamically balanced. The circumferential surface around the lower skeleton is
formed of a steel wire spiral or an expanded wire mesh, giving an openwork structure through which the air is discharged. The
free spaces of the operwork surface meet the requirements of suitable normatives. Therefore an accident access to the rotat-
ing impeller is practically impossible. The upper part of the fan is shielded by a hood made of a polyester-glass composite of
high mechanic resistance and extraordinary aesthetic features. The fan has to be mounted on a roof base. It is recommended
to apply a sound absorbing roof base type TPD-N or TPDC-N of adequate size adapted to the fan.
