DÜRR SUCTION SYSTEMS
Responsible dental medicine
The use of dental amalgam in dentistry
Worldwide demand is huge
Dürr Dental, a pioneer when it comes
has been characterised by its outstanding properties for easy processing and
long service life. Unfortunately, it does
put strain on our waste water streams
and the environment during processing
and after removal from the oral cavity.
Amalgam should not be part of the
clinic’s waste water and this is why it
should be collected from the waste
water from each treatment unit. Modern
dental treatment is consistently striving
to meet this challenge.
to suction systems for the dental surgery, looks back on many years of
experience with the ever more important worldwide task of amalgam separation. Since the 1980s, more than
10,000 surgeries were equipped with
Dürr amalgam separators “Made in
Germany” – adapted individually to
the existing suction system installed in
the surgery. When you select a Dürr
amalgam separator, you do not just
take a decision for its reliability, but also
for progress and innovation in dental
medicine and environmental technology.
Separation is mandatory
Separation is mandatory in many
countries with laws and regulations
requesting that raw waste water from
treatment units must be reduced by at
least 95 % before entering the normal
waste water stream. As an example,
the whole of Europe must conform to
the ISO standard 11143:1999 which
defines the minimum requirements for
amalgam separators. For Germany in
particular, the comprehensive design
and inspection rules of the Deutsches
Institut für Bautechnik (DIBT) in Berlin
are strictly followed.
Amalgam particles released during preparation need to be aspirated and separated.
Extensive amalgam fillings are very durable.
Once they are removed, however, heavy
metal particles occurring in large quantities
need to be disposed of.
Hazardous amalgam should not get into
the sewer – this is a legal duty as well
as a responsibility towards society and the
environment.

centrifugal forces. Dürr Dental makes
use of this fact with its highly effective
and patented centrifugal separation;
whether it be for the separation of the
mixture of air, secretions and solid materials or for the separation of amalgam
particles. Long years of development
involving studies of flow behaviour and
material optimisation have spawned
high-end technology which is vastly
superior compared to alternative sedimentary separators in terms of safety,
maintenance and hygiene. It works fully
automatically, is hydrodynamically selfcleaning and automatically indicates

amalgam separation, in a dental surgery has to function smoothly without
interfering with daily work routines. For
this reason Dürr Dental focuses strongly
on the performance and reliability of
the separation systems. Of course, Dürr

DÜRR SUCTION SYSTEMS
Universal solution for large
surgeries
The easiest way to equip multi-room sur-
geries with amalgam separation is the
Dürr CA 4. Installation is comparatively
easy. The only condition for so-called
“dry air” suction systems is that that
water drains need to be laid out separately from the waste water. The central
installation in a “wet” suction system,
by contrast, requires only one single
spittoon valve. Counselling and planning based on the different suction systems play a vital role when it comes to
making the right choice of investment.
With this regard, the specialised dealers
and service partners of Dürr Dental are
available for you worldwide.

CA 4 for the central separation of
up to 4 treatment units.
The Dürr CA 4 works completely independently within the suction system: As
soon as used water is produced in the
treatment units, the amalgam separator
switches on automatically. The flow rate
of up to 16 litres per minute is proof for
the consistently high performance, living
up to even the most challenging requirements, with the operation of 4 workstations in parallel. A display element in
the housing offers visual and acoustic
information on the operating mode. The
separation efficiency of nearly 99 %
exceeds by far the legally required minimum value.
Operation that suits the surgery
The Dürr CA 4 controls maintenance
tasks in the surgery: It monitors the fill
level of the amalgam collecting cartridge electronically and signals when
a replacement is due. The replacement
is carried out easily by the competent
assistant.There is no pre-planned date
or notice required, which takes considerable strain from the team. Packaged
and disinfected, the cartridge is safely
stored, waiting to be picked up.
The lever action handle releases the amalgam
collecting cartridge comfortably and safely.

DÜRR SUCTION SYSTEMS
Efficient air/water separation
and amalgam separation within
the treatment unit – CAS 1
In many countries, the planners of sur-
geries use “dry air” suction systems on
account of the difficult installation conditions. With such systems, the separation of air and water takes place in
every treatment unit. The easiest way
to retrofit amalgam separation to exchange the air/water separation is by
using a Dürr CAS 1 combination separator. Small, compact, silent and easy
to in-stall, it combines air/water separation and amalgam separation in one
single unit. The Dürr CAS 1 can be integrated in many treatment units and is
installed ex works by many leading
manufacturers. The two-phase system
with centrifugal separator and dynamic
separation turbine attains a much higher
separation performance than traditional
methods.
CAS 1 in the treatment unit –
powerful and silent.
CA 1 amalgam separator from the new
generation of Dürr C separators.
The amalgam centrifuge is self-cleaning
and achieves a tested separation efficiency of nearly 98 %. If an additional
rinsing unit is installed, the permanent
water film prevents the deposit of particles and the coagulation of blood. This
also improves the hygienic condition of
the whole suction system.
Amalgam separation next to the
treatment unit – CA 1
If the air/water separation system
cannot be replaced, it is possible to
use a Dürr CA 1 amalgam separator
in a practical housing next to the treatment unit. It offers a convincing separation efficiency of nearly 98 %, and
the robust design makes it a reliable
component of the suction system. The
Dürr CA 1 is ideal for the modernisation of a single-workstation suction unit
with integrated air/water separation
(e.g. Dürr VS 300 S) or a single-workstation water ring pump.
CAS 1 and CA 1 can be used externally

The Dürr 3-in-1-VSA technology
For single-room surgeries, Dürr Dental
combines the complex system consisting of suction unit, air/water separation
unit and amalgam separation unit in
one single combined suction unit – all
on a single drive shaft. This leading
technology not only reduces the maintenance effort, but also the number of
appliances. Top suction performance
combines with efficiency, robustness, a
long service life as well as a reduced
maintenance effort.
In case of older single-workstation suction units, retrofitting with an amalgam
separator is not economically viable. In
such cases, and where amalgam separation is legally required, the long-term
use of modernisation makes it advisable
to invest in a new Dürr VSA 300 S for
the surgery.

negative pressure required for a faultfree and perfectly safe hygienic treatment. A continuous suction power of
approx. 300 litres volume flow per
minute makes for perfect visibility in
the preparation area and prevents aerosol clouds, which could be harmful
with regard to hygiene! Before the separated used water is drained off by the
waste water pump, it is led into the
centrifuge, where the existing amalgam
particles are separated. More than
97 % of the amalgam is collected in the
collecting tank, whose fill level is automatically monitored. If a fill level of
95 % is reached, a visual and acoustic
signal indicates that the cartridge needs
to be replaced. The access to the cartridge is easy, making the replacement
simple and quick.

Systems by Dürr Dental help reduce the
costs for this to a minimum. And the
small effort is worthwhile for the environment, as is shown by current surveys.
For instance, 134 t amalgam reach the
raw waste water of dental surgeries
each year. A mandatory 95 % amalgam separation could reduce this value
down to 6.7 t. This means that environmental technology is the technology of
the future.

Concept including the hygienic
removal
Amalgam separation is not a one-way
street. The separation is followed by
safe storage in the collecting cartridge.
As Orotol® Plus is added, the content
of the cartridge is hygienically treated
to kill bacteria. The collecting cartridge
is picked up and reaches the disposal
process of authorised recycling companies. With regard to the transport,
please observe the regulations applying to your country.
Disposal in a qualified way
The disposal of amalgam waste from
dental surgeries is subject to strict regulations. Therefore full amalgam collecting cartridges are picked up directly
at the surgery by authorised waste disposal companies.
