Mobile star screen

The Multistar S3 is the entry-level member of Komptech’s professional star screen line. Designed expressly for the needs of lower to moderate volume users, the S3 combines low cost with a level of performance previously only available in the high-capacity L and XL class. Built on a hook lift module, it has small dimensions while still offering the requisite mobility for service providers or multi-site use. Like the higher capacity models, the applications range from compost to green cuttings to bark, chips and shredded waste wood. Similarly, almost all the options of the larger machines are available - wind-sifting of the medium fraction, screen deck variations, switch from 3 to 2 fractions, hopper extensions and much more.

  • Highlights

    The perfect start

    Low upfront costs don’t mean you have to forego performance or convenience. A large hopper with up to 3.5 m³ volume permits continuous loading. The 2.1 m² coarse and 3.9 m² fine screen decks are matched to it. The discharge conveyor height provides enough buffer capacity for smooth front loader use.

  • Highlights

    Always unclogged

    The screen units are continually cleaned by the most simplest and efficient patented CLEANSTAR cleaning system. Each star has a wear-resistant cleaning element that clears the screen gap to the surrounding stars on each rotation. So screening is always in season with Multistar star screens.

  • Highlights

    Saving with hybrid technology

    The power for the drives can come either from grid electric power or the optional built-in diesel generator. The use of grid power reduces energy consumption by up to 75% compared with diesel-hydraulic power.

  • Highlights

    A different kind of cladding

    Sheet metal panels with large access doors protect the drive components. Elsewhere, tough truck-grade tarp material protects components from dirt while saving weight and giving the machine a distinctive appearance. Rolling up the tarp sidewalls affords free access to all other components.

  • Highlights

    Semi-mobile with hook lift

    The substructure of the Multistar S3 is a standard hook lift frame. The machine can be transported easily by a 3 or 4-axle truck rated for 7 metre containers.
