6. Functional Description
Example showing suction unit VS 900
Inside the suction unit the aspirated fluids and
solid particles are passed through a two-step
separation system and separated from the suc-
tion air. This separation system consists of a
cyclone separator and a separation turbine.
The suction operation functions continuously.
The mixture drawn in consisting of fluids, solid
particles and air Luft passes through the inlet
connection (D) and into the suction unit. The
coarse filter (B) serves to hold the solid particles
back. The rest of the mixture passes to the
cyclone separator (I) and is set into a spiral mo-
tion. In this first step the centrifugal forces
generated cause the fluid and smaller particles
remaining to be thrown against the outside wall
of the separation chamber of the cyclone-
separator. This initially creates a coarse separa-
tion of the fluid waste.
In the second stage the separation turbine (J)
effects a fine separation of the remaining fluid
from the flow of air which has carried it so far.
The waste water pump (H) feeds the fluid ema-
nating from the centrifuge stage and together
with the finer solid particles through the waste
water system connection (E) into the central
waste water network.
The air which has been separated fro the fluid
mix in the second stage is drawn in by the vacu-
um pressure which is created by the turbine
wheel (K) and can now be passed through the
exhaust air connection (C).
Both the turbine wheels and the waste water
pump are driven by the motor (L).
In order to separate out any dental
amalgam present it is necessary to have
an amalgam separator, e. g. model CA
4, located behind the waste water con-
nection (E).
As the separation step of the VS 1200 S
is approved for use with up to 24 l fluid
then, depending on the particular instal-
lation and national regulations, a second
CA 4 must be connected to this unit.
The maximum permitted water volume
of 16 l/min for one CA 4 must not be
exceeded.
Where an amalgam separator pro-
vided by a different manufacturer is
connected then the max. fluid flow
volume of the suction unit must be
strictly observed.

8. Set-up
More information can be found in the
planning information for suction units.
8.1 Room for Set-up
• Installation in special purpose rooms, e. g. in
boiler room, must be checked first against
prevailing building regulations.
• Installation in wet rooms is not permitted.
• When installation is in a cabinet or a machine
room then sufficient intake and exhaust air
openings must be provided for; these must
have at least 120 cm² clear cross-section.
Where ventilation is not sufficient, then a venti-
lation fan must be provided with a perform-
ance of at least 2 m³/min; appropriate slots to
allow the intake of cool air must also be pro-
vided for.
When cabinet installation is preferred then a
special ventilation kit can be used.
8.2 Set-up alternatives
• On the same level as the surgery room or in a
room on a floor below.
VS 300 S
Where installation of the VS 300 S is carried out
in a cellar or similar room then the unit must be
set up on a platform or fixed to the wall at a
height of 30 cm above the floor level.
• Set-up on the floor and in combination with an
amalgam separator should be carried out us-
ing a floor unit or platform.
The suction unit itself should be set
up at least 20 cm above any ins-
talled Dürr amalgam separator that
might be present.
• For wall mounting we recommend the Dürr
wall mounting bracket.
• In well-ventilated cabinet (e.g. Dürr PTS).
• In Dürr housing (VS 300 S only)
as extension to the treatment unit.
Information concerning installation can
be found in the installation instructions
provided with the floor unit or the wall
mounting bracket.
8.3 Bacterial filter / noise reduction
(muffler)
Bacterial filter: for reasons of hygiene we strong-
ly recommend that a bacterial filter is provided
for in the exhaust air connection. Where the
suction unit is installed in the surgery rooms and
the exhaust air cannot be fed to the outside of
the building then a bacterial filter must be fitted.
Depending on the model type and condition of
the bacterial filter this must be replaced every
1-2 years at the latest.
Noise reduction muffler: where the noise of the
exhaust air extraction at the outlet is too loud
then a muffler can be installed into the exhaust
air line.
8.4 Installation of surge tank in
combination with amalgam
separator
• Suction units VS 600, VS 900 S and VS 1200
S require the installation of a surge tank when
used in combination with an amalgam
separator.
Information on installation can be found
in the installation instructions supplied
with the surge tank.
Where a VS 900 is replaced by a VS
900 S or VS 1200 S then we also
strongly recommend replacing the sy-
phon with a surge tank. (Order number
see under Special accessories.)
8.5 Rinsing Unit
When carrying out surgical treatments then we
recommend using a rinsing unit together with
the suction unit; this provides a small amount of
water during the aspiration phase which then
serves to thin the secretions which arise and
makes it easier to transport these through the
system.
The rinsing unit should be installed within the
treatment unit itself or set up in the vicinity of the
suction unit.

8.6 Tubing
The following materials may NOT
be used:
Acrylonitric butadiene styrene or
Styrol-copolymer-blends
(e. g. SAN+PVC).
Only the following plumbing materials may
be used:
airtight HT-waste water tubes of polypropylene
(PP), chlorinated polyvinyl chloride (PVC-C), un-
plasticized polyvinyl chloride (PVC-U) and poly-
ethylene (PEh).
8.7 Hose materials
The following materials may NOT
be used:
hose materials which are not re-
sistant to dental disinfectants and
chemicals, rubber hoses or full
PVC-hoses which are not sufficient-
ly flexible.
For waste water systems and suction connec-
tions only flexible spiral PVC hoses with integrat-
ed spiral or hoses of a comparable quality may
be used.
As all plastic hoses are subject to dete-
rioration with age, these must be
checked and inspected frequently and
replaced when necessary. When a suc-
tion unit is replaced, we recommend
that all hose connections also be re-
placed at the same time.
8.8 Hose and pipe laying
• Waste water connections must be carried
out in strict accordance with local and national
regulations.
The connection between the pipe line
and connection to the suction unit
should be kept straight, without bends,
and as short as possible using the flexi-
ble hoses provided. This will reduce the
amount of vibration in the plumbing
system.

10. Electrical Connection
The electrical connections must be car-
ried out observing any and all technical
regulations concerning the set up of low
voltage systems in areas used for medi-
cal purposes.
• Before start-up and first use the supply volt-
age must be compared with the voltage in-
structions to be found on the model identifica-
tion plate.
• When carrying out electrical connections to
the main power supply an all-polar insulating
device (all-polar circuit breaker or all-polar
power safety switch (fused)) with a minimum 3
mm contact opening width must be built into
the system.
• Suction units can only be connected to the
mains power supply using a fixed cable
connection.
• The suction unit is operated using the control-
ler located in the external control unit.

The suction unit can be connected to a control
unit which is either part of the delivery contents
or, if not, can be ordered as a special accesso-
ry. Connection plans and circuit diagrams can
be found in the Control Unit Installation and
Operating Instructions.
The control box is factory set for con-
nection to the suction unit; this should
be kept in mind when replacing the suc-
tion unit with a unit of a different size.
