Trislot Advantages

  • Reversibility = double lifetime. In this specific application the wear is concentrated on the top of the screen. Trislot® offers the possibility of reversible screens. If the wear on one side becomes too extensive, you simply turn the screen upside down.
  • Slot precision. This is one of the most important characteristics of the Trislot® screen as it determines the dimensions of the fibers passing through. Trislot guarantees a superb slot precision .
