INTRODUCTION
The purpose of the present Use and Maintenance Manual is to supply User with directions within the range of
application, assembly, start-up and operational use of the
BIG-2000/Ex
Filtering unit.
Prior to assembly at the place of operation and use, it is important to get thoroughly acquain-
ted with the contents of the present instruction.
With regard to continuity of work carried on improvement of our products, we reserve for
ourselves the revision possibility of the draft and technological changes improving their
functional features and safety.
Construction of

Methodology and requirements
PURPOSE
BIG-2000/Ex
is appropriate for cleaning the dust laden air from dry dust particles, arising during production
processes with occurrence of powdery materials and dust particles of ST1 explosiveness class. The appliance is
equipped with 2 cartridge filters, with antistatic polyester membrane
– functioning on the basis of surface filtration.
Admissible maximum temperature of the filtered air is 40ºC.
The device can be applied for such processes as:
–
grinding of non-sparking materials,
–
sand blasting, shot peening,
–
mechanical cutting of metals, gas-, plasma-, laser-, arc cutting of metals,
–
polishing, planishing,
–
processing of plastics,
–
metalization,
–
powder varnishing.
Basic advantages of the device are optimum filtration efficiency, long operational use (longevity) of the cartridge
filters, low power consumption and simple and fast maintenance. The appliance is admitted for use, according to
the Ex marking, for cleaning the air in areas of explosion hazard, according to the ATEX 137 1999/92/EC Directive.
According to ATEX, the operational conditions are specified (as for this device) as follows:
Ex II 3 D Ex tD A22 T200ºC. The subsequent markings are interpreted as
:
group II
– the device is designed for work in enterprises, in on-ground premises, in sites of occur-
rence of explosion atmospheres, except for application in areas of methane hazard
(
firedamp
)
, or risk
connected with carbon dust
;
category 3
– the device is designed for application in areas where explosive atmospheres are likely
to occur, whereby the explosive atmospheres are of low risk
;
D hazard
– flammable dusts
;
Ex
– the electrical appliance is designed for function in areas of explosion hazard
;
tD
– a marking for Ex protection category of the appliance – tight housing
;
A22
– control procedure A for the area 22
;
T200ºC – the surface temperature of any part
(
of the device
)
will not exceed 200ºC during normal
operation.
