Innovative blade geometry increases screening efficiency
MultiFoil rotors are the ideal combination of the highest screening quality and throughput rates. Innovative blade geometry prevents the spinning of fibers and reduces pulsations. Thanks to the uniform through-flow profile with short suction impulses, the MultiFoil rotor leads to improvements sustained screen openness with the highest separation rate. 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, whereby 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.
