Application
WP-D/Ex roof fans are meant for use in areas of explosion risk, where explosive atmos-
phere can occur, i.e. mixture of fl ammable substances in a form of gases, vapours and
mists with the air.
Due to increased pressure it is possible to apply the fans with local exhausts and with
the fi ltering units and also with a ventilation system of signifi cant resistances. The fan
can be used in installation with a roof discharge unit of a required dynamic rise.
Structure
The fan consists of:
– spiral housing,
– explosion-proof motor,
– radial impeller, mounted directly on the motor shaft,
– silencer – installed at the fan outlet,
– fl ange to install the fan,
– motor hood.
The basic elements of the fan (housing, impeller, silencer, fl ange) are made of non-
magnetic stainless austenitic steel whereas the motor hood is made of aluminium
plate. The whole fan is in a natural colour of stainless steel.

Technical Data:
V = 500 - 90.000 m³/h
P = 100 - 2.800 Pa
L = 0,37 - 55 kW

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.
