Multistar S3

Star screen with electric drive icon Diesel icon Electric icon Mechanical

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 class.

Built on a hook lift module, it has small dimensions while still offering the requisite mobility for service providers or multi-site use. 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.

Key facts

The perfect

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.


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.



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.


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.
