2.1 Intended use
The compressor vacuum pumps series VacuStar W were
developed to be installed into a superior system. The
manufacturer of the overall system must assess the new risks
resulting from the installation. These risks must be included in
the operating instructions of the system.
The VacuStar W is intended exclusively for the compression or
suctioning of filtered air.
The VacuStar W in the explosion proof design complies with
Directive 2014/34/EC (ATEX) and is suitable for conveying
potentially explosive gases and gas mixtures of explosion group
IIB, temperature class T2/T3 from potentially explosive zone 1 and
zone 2 areas.
No explosive atmosphere is allowed in the area around the
VacuStar W. The VacuStar W may only be opened when it is
stopped and when there is no explosive atmosphere around it.
Marking of the VacuStar W:
II 2G c IIB T2 (i) (for VacuStar W without cell ventilation)
II 2G c IIB T3 (i) (for VacuStar W with cell ventilation
and
no potentially explosive external atmosphere).
The gas temperature in temperature class T2 is restricted to
220 °C and in temperature class T3 to 195 °C and must be
secured.
The vacuum must be secured to 200 mbar for temperature class
T2 and to 100 mbar for temperature class T3 (only with cell
ventilation).
