The mixture of liquids, solid particles and air drawn in passes through the inlet connection and into the
suction unit. The coarse filter holds back the solid particles.
Inside the separation unit, the aspirated fluids and solid particles pass through a two-stage separation
system and are separated from the suction air. This separation system consists of a cyclone separator
and a separation turbine.
The aspirated mixture flows into the cyclonic separator, where it is set into a spiral motion. In this first
stage, the resulting centrifugal forces force the fluid constituents and any remaining solid particles
against the outside wall of the separation chamber of the cyclone separator. This initially only effects a
"coarse separation" of the fluid.
In the subsequent second stage, the separation turbine effects "fine separation" of the remaining liquid
from the air flow that has carried it to this point.

The fluid and solids accreting in the separation chamber are continuously fed to the amalgam centri-
fuge, where the amalgam particles are removed. The fluid extracted via the centrifuge is fed through the
waste water valve and the outlet connection into the central waste-water system.
Under the centrifuge there is an interchangeable collecting container into which the separated amalgam
particles fall once the motor is switched off.
A sensor checks the fill level in the collecting container, and when it is full, an LED on the display panel
indicate that the collecting container needs to be replaced. Depending on the type of work carried out
and the amount of amalgam arising, the collector vessel should be changed approx. every 6-9 months.
A secure twist cap makes the replacement and closing of the collector vessel easier.
A pump connected to the centrifuge keeps the fluid level constant in the collecting container. This pre-
vents accidental overflow when replacing the collecting container.
The air separated from the liquid is sucked off by the vacuum pressure generated by the turbine wheel.
The air is then blown through the noise reduction hood and over the exhaust air connection and out of
the machine.
The turbine wheel, separation turbine and amalgam centrifuge are driven by the motor.
An auxiliary air nozzle is connected to the turbine housing. The auxiliary air nozzle limits the vacuum in
the system. In certain working situations it also sucks additional cooling air into the machine.

surgery room or in a floor below.
Further information can be found in our
suction planning information leaflet. Order
number9000-617-03/..
6.1 Installation/setup room
The room chosen for set up must fulfil the follow-
ing requirements:
– Closed, dry, well-ventilated room
– Should not be a room made for another pur-
pose (e. g. boiler room or wet cell)
Ambient and environmental conditions
must be taken into account. Do not oper-
ate the unit in damp or wet conditions.
– When installing in a cabinet the inlet and outlet
ventilation slots must be present; minimum
free cross-section at least 120 cm2.
– Forced ventilation (fan) must be provided if
there is a risk that the recommended room air
temperature could be exceeded. The air flow
performance must be at least 2 m3/min.
– Do not cover cooling slots or openings with
housing installations; ensure sufficient clear-
ance to the openings to permit sufficient cool-
ing.
6.2 Setup options
The following options for setting up the unit are
available:
– Wall installation using a Dürr Dental wall
mounting
– In a ventilated cabinet
– In a Dürr Dental noise reducing housing
When installed in a basement or a similar
room, the unit must be placed on a base
or be fixed to the wall at a minimum
height of 30 cm above the floor.
6.3 Use of nitrous oxide
This unit is technically suitable for the aspiration
of nitrous oxide (laughing gas). However, when
assembling a system for aspiration of nitrous
oxide, it is important to ensure that the other
components in the system are also suitable for
this purpose. Those responsible for setting up
the system must assess this and approve and
release the system for the aspiration of nitrous
oxide.
Operation with nitrous oxide is only per-
mitted if the exhaust air is transported
from the unit to the outside of the build-
ing.
6.4 Pipe materials
Only use vacuum-sealed HT-waste pipes
manufactured from the following materials:
– Polypropylene (PP),
– Chlorinated polyvinyl chloride (PVC-C),
– Plasticizer-free polyvinyl chloride (PVC-U),
– Polyethylene (PE).
The following materials must not be used:
– Acrylonitrile-butadiene-styrene (ABS),
– Styrene copolymer blends (e.g. SAN + PVC).
6.5 Hose materials
For waste connections and suction lines only
use the following hose types:
– Flexible spiral hoses made of PVC with inte-
grated spiral or equivalent hoses
– Hoses that are resistant to dental disinfectants
and chemicals
Plastic hoses will display signs of ageing
over time. Therefore, they should be
inspected regularly and replaced as nec-
essary.
The following types of hoses must not be
used:
– Rubber hoses
– Hoses made completely of PVC
– Hoses that are not sufficiently flexible
6.6 Installation and routeing of

7 System components
The system components listed below are
required or recommended for various procedures
or for installation.
7.1 Rinsing unit
In the absence of a spittoon or rinsing unit in the
treatment unit, it is absolutely essential that a
rinsing unit be installed in the VSA 300 S. In addi-
tion, for surgical procedures and for procedures
using airflow a rinsing unit must always be instal-
led in the treatment unit to supply a small amount
of water to the system during aspiration. Any
secretions present will thus be diluted and can be
transported away more easily.
For further information, refer to the rinsing unit
installation and operating instructions
7.2 Spittoon valve
To ensure that the waste water from the spittoon
bowl is directed into the suction pipe, a spittoon
valve needs to be installed between the drain of
the spittoon bowl and the suction pipe. The spit-
toon valve must switch on the suction machine if
required.
7.3 Flow accelerator
In order to keep the suction system free of
deposits, a flow accelerator can be fitted in con-
junction with a spittoon valve. When using a bowl
rinse system, water will collect before the flow
accelerator. The next time suction takes place
using the large cannula, the collected fluid is
transported in surges and at high speed to the
suction system. This ensures automatic cleaning
of the suction pipes.
7.4 Exhaust air filter
For hygienic reasons, we recommend the instal-
lation of a bacteria filter in the exhaust air line.
If the unit is installed in the surgery and the
exhaust air cannot be discharged to the out-
doors, it is essential to install a bacteria filter.
Depending on the type and condition of the bac-
teria filter, it will need to be replaced every 1‑2
years at the latest.
The separation integrated in the system
does not retain bacteria; this is why we
recommend installing a suitable filter in
the exhaust air system.
7.5 Noise reduction
If the noise level from the exhaust air vent or the
flow noise generated is too high, noise reduction
can be installed in the exhaust air line.

8 Installation
The actual connection can vary depending on the chosen installation option. The connection
shown is only an example.
8.1 Installation and routeing of hoses and pipes
❯Establish connections between the pipe system and the unit using the flexible hoses supplied. This
will prevent vibrations from being transmitted to the pipe system.
❯The connection between the pipe line and unit suction connection should be kept as short as possi-
ble and straight, without bends.
❯Install the drain hoses with a downward gradient so that the waste water can drain off.
❯Waste water connections must be implemented in accordance with applicable local and national reg-
ulations.
