Application
WPA-P-N fans have been designed both, for air-supply ventilation
and
extraction ventilation of
rooms and workplaces.
They
can be applied for general ventilation and for local exhausts.
Addi
-
tionally,
WPA-P-N
fans can be used or drying the humid rooms
by forcing the multiple air exchan-
ges.
Do not
use the fan for conveying the aggressive gases or substances creating explosive atmos-
pheres with the air. In general, the fan is designed
for transporting the air, of dustiness not ex-
ceeding
0,3 g/m³, without viscous impurities, aggressive contamination or compounds creating
hazard of explosion.

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.
It is unacceptable to install on the
device structure
any additional elements not belonging to
its normal construction or accessory set.
C.
Any structural changes or modification of the device,
carried out
by
User
on one’s own are
not permitted.
D.
Protect the housing from mechanical damage.
E.
The
fan cannot
be
used for conveying
the
air contaminated
with a
mixture of flamma-
ble substances
in form of gas, vapour, mist and dust that in connection with the air
create the explosive atmosphere
.
F.
Do not use
the
fan
for
conveying the air containing viscous impurities
that could
accumulate
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.
