D20 - the solid construction site mixer

The D20 mixer is a robust all-rounder for processing dry mortar products with a granularity of up 4 mm. It is the best-selling mixer within this class and, depending on the version, rationalises the processing of finishing plaster, masonry mortar or fine concrete.

The 230V version specialises in the processing of finishing plaster and therefore is fitted with the versatile standard mixing chamber with plain bearing. It is also available in a 400V version, which exhibits its benefits in the processing of heavy materials such as masonry mortar and fine concrete. In doing so the ball-bearing mounted fine concrete mixing chamber is used.

The D20 is filled with bagged material as standard and impressively offers homogeneous blending. The large material container fulfils requirements of the construction site.

The clear layout of the controls enables intuitive operation. As is typical of m-tec systems, the D20 has easy and quick to use connection systems that enable important elements, e.g. the mixing chamber, to be replaced in just a few seconds.
