2. Application
WPA-D-N/Ex explosion-proof roof fans are intended for use in areas of explosion risk, where
explosive atmosphere, (i.e. mixture of flammable substances in form of gas and vapour with
the air, whereby after ignition –in atmospheric conditions –the burning mass would expand
within the whole non-burning mixture) is likely to occur. The fans have been constructed for
application within temperature range -20 up to 40C. The forwarded air must be dry, of dus-
tiness not exceeding 0,3 g/m3, without viscous, aggressive contaminants and of maximum
temperature +60C.
Increased fan pressure guarantees their application in systems with local exhausts and filte-
ring units, and additionally in ventilation ductings of significant flow resistances.
According to the 2014/34/EC ATEX Directive and EN ISO 80079-36 the device carries the
level of protection: “HIGH” –as a device classified for Group II, Category 2, and it can
work in areas where explosive atmospheres are likely to occur. The fan can be applied
in zones 1, 2(G).

5. Structure and Function
The fan consists of a spiral steel housing, Ex motor, aluminium radial impeller (directly instal-
led on the motor shaft) and a steel sheet motor hood. The impeller blades feature a shape
of an aeroplane wing and they provide low noise level. The fan inlet is equipped with a flange
to install the fan on a roof base or on a wall bracket.
Typical feature of the fan is the silencer, fastened at the outlet of the spiral housing.
For safety reasons, both inlet and outlet are equipped with a protective grill. It is recommended
to install the TK silencers at the fan inlet (see acoustic data in Table No.1).
ADDITIONAL EQUIPMENT –delivered on separate order:
■ roof bases or wall brackets
■ silencers
The fan housing is equipped with a protective cable to dissipate the electrostatic charges away.
There is a terminal for the protective cable on the motor housing. Additionally, there is located
a terminal box for supply. Hemispheric motor hood is of aluminium sheet and protects from at-
mospheric factors / weather conditions.
6. Assembly and Start-up
The appliance can work outside the industrial rooms (outdoor application). Manufacturer sug-
gests installing the fan on the roof base or on a wall bracket (as an element of optional equip-
ment constructed upon separate documentation).
The inlet- and outlet connection fitting pieces ought to be fastened to the ventilation system
by means of flexible connectors (of antistatic material). The way of fastening of the connections
depends on the established technologies of the system execution and should be specified at
the site of installing. User performing the assembly is strictly responsible for full compli-
ance with the provisions of EN ISO 13857.
6.1. Guidelines of installing:
a/
VENTILATION SYSTEM –to which the WPA-D-N/Ex fan will be connected,
must be designed and executed in accordance with the valid regulations and
standards –according to the local conditions of explosion risk.
b/
SUPPLY SYSTEM - to which the WPA-D-N/Ex fan shall be connected must be
designed and executed in accordance with the valid regulations and standards
–according to the local conditions of explosion risk.
–
Prior to connection, make sure if the parameters of the hitherto existing electrical supply sys-
tem, are in accordance with the parameters on the nominal plate. Otherwise, the connection
steps cannot be executed.
–
Any steps of connection activity can be carried out by an authorised person with qualification
–according to the valid regulations and standards.
–
The whole ventilation system must have the efficient performed installation dissipating the
electrostatic charges. Any joints / connections between ventilation sections should have
electrostatic connections made of protective cable.
–
Check if the metal ducts are grounded correctly. Additionally, provide the grounding to the
motor housing, by joining the protective cable with the contact on the motor housing.

Disconnect the fan from the power supply. Exemption from this are
activities that must be executed at the running fan, i.e. vibration mea-
surements (especially here are important safety regulations).
–
Wait until the fan impeller stops rotating.
The fan can be restarted after the control steps, (described in Section 6 “Assembly and Start
-up”), are carried out.
10. Occupational Health and Safety
Start-up and the operational use of the fan are admissible after getting acquainted with
the contents of the present Use and Maintenance Manual. The fan shall not cause any ha-
zard under the condition it is correctly and firmly installed on the roof base or other structural
element of the building.
Any installation activities related to the power supply system, have to be carried out strictly ac-
cording to the enclosed Connection Diagram and in accordance with the instructions given in
Section 6 of the present Use and Maintenance Manual.

12
