The
WAMFLO
®
ATEX
dust collectors components are suitable for use in complex systems in the presence of
potentially explosive atmospheres as defined in the ATEX Directives.
In the event it is ordered a filter version equipped with anti-explosion panel (option) and the dedicated
WAM
®
hopper, the resulting unit body + panel + hopper represents a complete system, entirely suitable to ATEX Di-
rective (within the limits of use defined in this manual).
Otherwise, if the dust collector is supplier without the hopper manufactured by
WAM
®
, the protection system
could NOT BE SUITABLE. In this case, in designing phase, the installer has the responsibility of sizing suitably
(according to ATEX Directives) the possible protection system.
3.5 Notes on safety standards
Danger - Warning
The filter can be used safely in applications inside buildings by using protective technical measures
different from the controlled explosion venting system described earlier; for these special applica
-
tions, please consult our Engineering Dept.
Danger - Warning
The technical standards regarding prevention and protection against explosions require, in addition to
the explosion venting systems, correct subdivision of the filter. Specifically, the installer or user must
isolate the filter from the other parts of the plant providing isolation devices on the IN/OUT ducts (for
example; rotary cells, ventex, slide valves with rapid closure mechanism) in such a way as to ensure
that, in case of an explosion, it is not propagated towards the systems connected to the filter. All these
protection systems must be ATEX-certified. Calculation of the distance for positioning the barrier must
be done by qualified personnel and according to the subdivision system applied; for these applica
-
tions, consult our Engineering Dept.
Danger - Warning
If the filter is provided with a maintenance door, (FNXS - FNXB), the resistance to internal overpressure
is 1 barg. The maximum negative pression permitted is -0.5 barg.
Danger - Warning
THE CONFIGURATIONS OF THE WAMFLO
®
ATEX FILTER FOR ZONE 22 ARE NOT FLAME-PROOF.
The user must certify the plant on which the filter is to be installed, taking this warning into considera
-
tion, to apply the necessary warning notices or fence off the area which may be affected by the flames
in case of explosions.
