1. Introductory Remarks
The purpose of the present Use and Maintenance Manual is to supply User with directions within the range of application, installation, start-up and the use of the WP-11/Ex explosion-proof
duct fans.
Installing, start up and operational use are exclusively admissible after getting acquaintted with the contents of the Use and Maintenance Manual.
With regard to continuity of work carried on improvement of our products, we reserve for oursel-
ves the revision possibility of the draft and technological changes improving their functional fea-
tures and safety.
Construction of the WP-11/Ex explosion-proof duct fans meets the requirements of the current
state of technology as well as the safety and health assurances included in:

2. Application
Duct fans are designed for general ventilation of the rooms, where explosive atmosphere, (i.e.
mixture of flammable substances in form of gas and vapour with the air, whereby after their
ignition – in atmospheric conditions – the burning mass would expand within the whole nonburning mixture) is likely to occur.
the whole non-burning mixture) is likely to occur.
The appliances are meant for installing inside the rooms (indoor application), directly in the
system of round ventilation ducts. They have been constructed for application within temperature range -20 up to 40C.
The forwarded air must be of dustiness not exceeding 0,3 g/m3, without viscous pollutants and
without aggressive compounds, and maximum temperature 60C.
According to the 1914/34/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).
Specification of the operational zones and the knowledge on hazards caused by atmosphere of explosion risk in those zones – belongs to operator of the appliance.
The appliance is marked on the nominal data plate:
II 2 G c Ex eb IIB T3
Marking of the operational conditions of the device: group / category / hazard / class.
marking for explosion proof properties of the appliance,
group II – the device is designed for on-ground work, in factories, in areas of explosion
hazard, but this cannot be methane (firedamp) hazard neither carbon dust occurrence,
category 2 – the device is designed for application in areas where explosive atmospheres are likely to occur,
gas hazard G,
“c” – category of protection against the ignition – constructional protection,
Ex – mark of the electrical device – constructed and tested according to the European Stan-
dards for work in areas of explosion hazard,
execution “e” – type of construction of the motor (a motor of increased safety)
“b” – protection by means of controlling the ignition sources,
gas explosion group IIB – occurring in on-ground factories – the fans are constructed according to the PN-EN 14986:2009, whereby they can be applied for gases in explosion groups
IIA and IIB and hydrogen,
temperature class T3 – the surface temperature of any part of the appliance should not ex-
ceed 200ºC (during the normal operation). The device can be used safely in explosive atmospheres belonging to temperature classes T1, T2, T3.
3. Reservations of Producer
A.
Manufacturer accepts no liability for any consequences following from the operational use
that is in contradiction to the purpose of application.
B.
Installing of any additional elements not belonging to the normal device structure (or acces-
sory set) is not acceptable.
C.
Do not undertake any structural changes or constructional modifications on the device on
one’s own.
D.
Protect the appliance’s housing from mechanical damage.
E.
Prior to installing check the load carrying capacity of the building structure where the device
will be mounted. Unsure mounting could cause hazard to personnel/people in vicinity and
effect in damage of the device.

F.
Do not use the fan for conveying the air containing viscous impurities that
could deposit (build up) on the device surface, especially on the impeller.
G.
Neither use it for forwarding the air with aggressive pollutants which
will destructively effect the device structure.
H.
During operation, the maximum impeller rotations should not exceed the nominal rotations.
I.
Manufacturer is not responsible for wounds, injuries, body laceration experienced
by User or personnel during the improper operational use.
