The Headworks® Spiralman in-channel screen is a shaftless spiral screen that combines screenings, conveying and compacting in a single reliable unit. As the shaftless spiral rotates, it clears screenings from the perforated sieve and conveys them out of the channel. The Spiral is fitted with a brush in the Sieve Zone to keep the screen clean. The solids continue through the Transport Zone, through the optional Wash Zone and ultimately to the Dewatering Zone prior to discharge. To make maintenance both accessible and easy, the entire length of the shaftless spiral screen sits in a U-trough. The Spiral remains the same diameter over its entire length, reducing the potential for blocking. The spiral in the Sieve Zone is bolted to the transport spiral and can easily be removed for brush replacement in a safe and comfortable environment.

  • Less danger of blocking. The diameter of the sieve and transport spiral are always the same size throughout.
  • Blocking cleared faster and easier with U-trough design. If blocking does occur, it is cleared faster and easier because of the U-trough design of the transport section.
  • Effortless maintenance features. The sieve spiral section of the in-channel screen is bolted to the transport section, making maintenance and brush changes easy.
  • Add-on products to boost efficiency. Any Headworks shaftless spiral screen may be combined with the optional Wash Module and/or Bagging Module.
