Screen baskets and rotors for all screening applications
Your paper quality starts with screening efficiency
Slot screen baskets
In recent benchmark studies, C-bar proved to be the most reliable slot screen basket in terms of high efficiency and throughput rate with the lowest specific energy consumption and minimum fiber loss. This success is based on the unique C-bar profile, paired with overlapping bar design arrangement.
The C-bar screening cylinder is applicable for all kinds of stock in the most varied stock preparation and approach flow processes. One major advantage: The C-bar basket can also be used for high stock consistencies and trash loads.

C-bar HerculeXX – even stronger than HerculeX
With innovative end ring-cylinder connection
The C-bar HerculeXX has been developed precisely for these requirements. This screen basket combines the hybrid technology of the HerculeX with an innovative screw connection of the end rings to the screen cylinder – all the while retaining the high open screen surfaces.
In addition, the unique screw connection of the end ring offers the possibility to reuse it when replacing the screen cylinder, which contributes to a sustainable material usage reduction.
C-bar Screening Cylinder
The high-performance screen basket for efficient screening
C-bar screen baskets are unique. Their overlapping bar design protects the slots from high wear and keeps the slot widths constant over their whole lifetime.
Your benefits with C-bar Screening Cylinders
- High throughput because of large open screening surface
- Improvement in quality because of high separation rates of dirt and impurities
- Low fiber loss because of precise processing
- Energy-efficient and long-lasting mode of operation
- NDura quality screen basket material guarantees high basket strength
- Wear protection through Voith hard chrome-plating technology
- Quick and flexible delivery times with constant and reliable quality
We celebrate our 1,000th HerculeX
Strong. Solid. Stable.
To withstand the enormous flow and pressure conditions in screening applications, Voith has developed the strongest screen basket on the market – C-bar HerculeX.
Thanks to the new and innovative hybrid technology, the screen basket copes with maximum loads. In combination with C-bar technology, which has been used successfully for over 25 years, it is the ideal screen basket for applications with demanding requirements.
In combination with the proven Voith EclipseRotor, an optimal and reliable screening process will be achieved. The C-bar HerculeX screen basket can be used in all Voith and non-Voith sorters.
Your benefits with C-bar HerculeX
- Maximum stability in applications with high stock consistencies and rotor speeds such as broke screening and pre-screening
- Efficient screening due to individual adjustment of slot widths and geometries combined with proven C-bar technology
- Low investment costs compared to welded or bonded screen baskets
- Cost savings for screen maintenance
- Maximum throughput due to large open screen area
- Long service life thanks to wear-resistant material
C-bar HerculeX D
Strong version with breaker bars
Your benefits with C-bar HerculeX D
- Suitable for extremly high trash loads
- Breaker bars prevent accumulation between rotor and basket
- Overlapping profiles avoid wear in the slot
- For all grades and all process steps
- Highest open area due to overlapping design
Higher capacity with lower energy consumption
Your benefits with C-bar C
- Large, open screening surface
- High sticky removal efficiency
- Less energy consumption
- High stability with welded profile bars
- Suitable for all centripetal screening machines
Hole screen baskets
The Voith NDura hole screen basket offers precise and reliable technology for centrifugal pressure screens. They are ideal for use in stock preparation, as well as broke, pulp and approach flow screening.
The optimization of the pitch design leads to an achievement of the highest open screen areas and, as a result, to a high throughput. The high separation rates of dirt and impurities contribute to quality improvements in the end products. Constant advances in our manufacturing techniques yield the highest precision in different hole designs and roundness of the screen basket. Each screen basket is equipped with the Voith hard chrome-plating technology and possesses a high wear protection.
The highly sophisticated products are suitable for Voith screens and for all current machines and associated rotor combinations of other manufacturers.
Higher demands in raw material screening require increased screening efficiency and pose distinct challenges for facility operators. Voith screening rotors are the ideal answer, combining maximum screening quality and throughput with optimal energy use in each area of application.
Unique geometry for maximum energy savings
Because of its novel foil geometry and configuration, the EclipseR rotor facilitates optimal screening efficiency, especially in screening applications that are heavily loaded with impurities. The flat but effective foil geometry of the EclipseR rotor generates a strong suction impulse and keeps the screen free for the highest throughput, even with high pulp consistencies of up to 5%. The EclipseR rotor was developed specifically for screening applications that are energy-intensive and heavily loaded with impurities. It is suitable for use in stock preparation, broke and pulp screening by Voith screening systems and all common machines from other manufacturers.
Innovative blade geometry increases screening efficiency
In addition, the concept causes lower pulsations and longer basket service life. Due to the oblique arrangement of the short blades, the rotor is noticeably less susceptible to spinning. Frequently, the rotor speed can be reduced, thereby fiber-preserving and energy-saving screening becomes possible. MultiFoil rotors were developed for use in stock preparation and approach flow and can be used for Voith screens and machines of other manufacturers.
