Use in a potentially explosive atmosphere
The fan has been designed and built to operate in environments where the presence of a potentially explosive
atmosphere is not expected, in other words it is not intended to handle materials which release explosive dust.
Emission into the atmosphere of harmful particles or gases must be contained within the limits established by
current regulations.
Modifications made to the fan which do not come into the categories of normal
and special maintenance, or which alter its operational and performance
characteristics, invalidate the machine’s compliance with the requirements of the
applicable directives, as attested by the manufacturer with the EC declaration
of conformity: it is up to the person responsible for the modification to resubmit
the machine to the assessment conformity procedures specified in the applicable
directives.
The fan has been designed and built in such a way that it CANNOT operate in a
classified area, according to directive 1999/92/EC.
