2. Application
WPA-P-N/Ex explosion proof portable 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), the burning mass would expand within the whole non-burning
mixture}
can occur.
Increased fan pressure of the device makes possible to apply it in a system cooperating with
local exhausts, filtering units, as well as in a ventilation system of significant flow resistances.
The fans can work within temperature range -20

C up to +40

C.
They
are meant for forwarding the dry air of dustiness not exceeding 0,3 g/m³, without viscous
impurities, aggressive compounds and of maximum tempe60

C.
According to the ATEX 2014/34/EC Directive and the standard PN-EN 13463-1 the appliance
provides level of protection:
HIGH as appliance classified in group II , category 2 and designed for application in areas where
explosive atmospheres are possible to occur . It can be applied in zones 1 , 2 ( G ).
The appliance is marked on the Ex classification board: II 2 G c Ex e II T3
Marking of the operational conditions of the device
–
group/category/hazard/temperature class.

marking for explosion proof properties of the device,

group II
– the device is designed for work as on-ground application, in places where explosive
atmospheres occur, but this cannot be methane risk (fire-damp) , neither carbon dust,

category 2
– the device is designed for application in areas where explosive atmospheres
are
likely to occur ,

gas hazard G ,

“
c
” – refers the constructional protection,

Ex
– mark of the electrical device – constructed and tested according to the European standards
for work in areas of explosion risk,

execution
“
e
” – type of construction of the motor (a motor of increased safety)

gas explosion group II
– occurring in plants on ground – the fans are constructed according
to the PN-EN 14986:2009, whereby they can be applied for gas in explosion group IIA , IIB
and hydrogen ,

temperature class T3
– the temperature of any part of the device should not exceed 200ºC
;
the device can be used safely in explosive atmospheres belonging to classes T3 , T2 , T1 .
