Filtered For your advantage
Why plastic melts love Gneuss Filtration
When selecting a Screen Changer or Melt Filtration System, the operating efficiency must be
considered: not only the investment costs, but also the operating costs. For example the screen
element costs, throughput variations or the creation of off grade product during screen changes
or the back flushing waste from self-cleaning systems should be considered.

The advantages of the RSFgenius Filtration System
Fully-automatic mode of operation with integrated self-cleaning
The filtration system operates fully-automatically and ensures 100 % availability of the line. Depending on
the contamination level, a screen change (which takes approx. 20 - 30 minutes) is carried out approx. every
1 - 16 weeks and has no influence on the production process and product quality.
Constant melt pressure, temperature, viscosity and throughput
By always keeping the size of the active screen area constant, pressure, temperature, viscosity and throughput of the melt remain constant, which guarantees the highest end product quality.
Guaranteed melt purity and quality, short dwell time of the melt
Optimal flow channel design and encapsulation guarantee lasting purity and quality of the melt after the
filtration. The short dwell time of the melt in the filtration system (< 1 minute) permits quick material or
color changes. Filtration finenesses down to 1μm are possible.
Simple and safe screen changes, low filtration costs
Screen changes do not expose personnel and environment to any danger. With the fully encapsulated design
of the RSFgenius, influences from the environment (e.g. moisture, oxygen) during the filtration process are
excluded. Due to the very effective screen cleaning with high pressure impulses, screens are automatically
re-used 100 - 400 times (depending on the filtration fineness).
Compact size and minimal installation effort
The small and compact design of the RSFgenius makes a simple and cost-efficient integration possible
even in a very confined space. Thanks to the compact design and the high quality insulation, the energy
consumption is extremely low.

kept constant and that the pressure upstream of
the filter increases only slightly during the whole
production process.
After the cavities have passed through the melt
flow, the screens can be removed without disturbing the production process.

The advantages of the SF Filtration System
Constant melt pressure, temperature and viscosity
By always keeping the size of the free active screen area constant, the pressure can be kept constant
during the whole production process (max. pressure variations of ±1.5 bar). Also, melt temperature and
viscosity are permanently free from variations. Thus, the end product quality is always constant.
Melt purity and quality are always guaranteed
Melt purity and quality downstream of the filtration system are permanently achieved. Rheologically optimized melt flow channels.
Very short dwell time of the melt
Due to the optimal rheological flow channel design, the dwell time of all the melt in the filtration system is
very short (< 1 minute).
Simple handling during screen changes
The operator is informed in time about upcoming screen changes by the control system. Changing screens
is a simple and quick procedure and does not have any influence on the process and product quality.
Compact size and simple installation
The compact design of the SF makes a simple and cost-efficient integration possible even in a very confined space. Thanks to the compact design and the high quality insulation, the energy consumption is
extremely low.

Applications SF
The SF was the first ever Rotary Filter and is running on many applications for over 25 years now.
This model is suitable for most applications but is
used today mainly on PVC processes and in the
manufacture of PS foam sheet.
The rheologically optimized, extremely streamlined melt flow channels with no dead spots come
into their own when processing rigid PVC, together with the pressure-stable operation (± max.
1.5 bar guaranteed) this system offers.
SF in the manufacture of foam sheet
Thanks to the constant processing conditions with
regard to shear, pressure and temperature, burn
ups can be avoided. The SF Melt Filtration System
is used on both rigid and flexible PVC, for example
in recycling or blown and cast film, as well as in the
manufacture of pipes and tubing.
SF in PVC processing
typical applications for SF:
Sheet manufacture:
Semi-finished products:
• Thermoformingsheet/
• Pipes
• Sheet

• Foamsheet
• Profiles
• Blownfilm
• Tubes

KSF
Permanent process consistency
The KSF Filtration System guarantees a constant production process. As neither pressure spikes
nor degraded material are created, melt purity and a constant product quality are guaranteed.
Further, short flow channels – free from dead spots – guarantee a short dwell time of the melt.

TheadvantagesoftheKSFFiltrationSystem
No pressure spikes during screen changes
Since the active screen area is enlarged during screen changes, no additional pressure increase is caused.
Pressure spikes are avoided.
No degraded material during screen changes
Since the filter disk always turns in one direction, self-cleaning is ensured. This avoids the creation of
degraded material. Furthermore, the filter disk can be cleaned completely without any problems.
Very short dwell time of the melt
Dead spots in the filtration system are avoided by matching the melt channel to the individual application.
Therefore, the lowest possible pressure drop as well as the shortest dwell time of the melt in the system
are guaranteed.
Simple handling during screen changes
The operator is warned by the control system in advance of automatic screen changes. The changing of the
screen packs is a simple and quick procedure. The control system can also be configured to run through a timedependent change sequence (e.g. during 1 week). This is recommended for production cycles < 1 week.
Compact size and simple installation
The small and compact design of the KSF makes simple and cost-efficient integration possible even in a very
confined space, and guarantees process-constant filtration even at high melt pressures.

The advantages of the HSprimus and HSSprimus screen changers
Sturdy design
The metallic sealing system is highly wear-resistant. It is, however, flexible and guaranteed leak-free even
with low-viscosity melts up to 800 bar.
Optimum rheological properties
The rheology of the melt channel and the inner parts of the screen changer can be individually adjusted to
the specific requirements. There are no edges, “dead spots“ and no seals. These screen changers are therefore excellent for PVC.
Short residence time
The residence time of the melt in the screen changer is < 1 minute, which ensures that material or color
changes can take place quickly and without problems.
Simple handling during screen changes
A screen change can be made at any time (even while the production is running).
Maximum screen surface area
The increased screen surface area of the HSSprimus leads to great technological and economic advantages
without rheological compromises – especially for twin screw extruders, but also for single screw extruders.
Applications HSprimus and HSSprimus
The HSprimus is intended for applications where continuous filtration is not required. For example where
only virgin material is used or only “safety net” filtration is required.
