Function

The ATMOS S 351 Natal is a mains-operated suction unit. The
quiet, maintenance-free diaphragm pump forms the core of
the ATMOS S 351 Natal. It creates a vacuum in the collection
jar which assists in drawing off and collecting the secretions.
The fi nal vacuum required and thus the suction power can be
preselected in steps with the press of a button. The ATMOS S
351 Natal produces this vacuum with the aid of a micro-proc-
essor-based controller. The pump switches off when the set
value is reached. A control circuit ensures that the pump only
runs when the vacuum is less than the value set.
The electronic fi lling level control, a safety jar (optional) and a
bacterial fi lter prevent secretions being sucked into the unit.
Various monitoring and control functions increase the ease
of operation of the ATMOS S 351 Natal and ensure safe use.
These are, for example:
– Electronic fi lling level monitoring of the collection jar which
provides visual and acoustic signals when the maximum
level is exceeded.
Electronic fi lter monitoring signalling a blocked (clogged)
–
fi lter audibly and visually.
–
A monitoring function which checks all main equipment
functions at regular intervals and activates a service re-
quest indicator if a fault is detected.
All components which come into contact with the secretion,
such as hoses, collection jar, lid system can be autoclaved
o
(up to 134 C, 4 min.).
A special equipment trolley can be supplied for mobile use.
