Knauf PFT - LOTUS XS screw mixer

LOTUS XS The small, handy and inexpensive screw mixer

The horizontal PFT screw mixers of the LOTUS series (also called mortar mixers) continuously and fully automatically mix all ready-mix dry mortars based on lime and cement (e.g. masonry mortar, jointing mortar, levelling compounds, adhesive/reinforcing mortar). A special feature of the model is the metering and mixing shaft as a single unit without a central axis and with a rubber outlet fabricated from a single piece. The rotating dosing segment doubles the service life of the wear part. The LOTUS XS FC-230V version is a small, handy mixer for bagged goods with an AC connection. The innovative special mixing shaft ensures homogeneous mixing at low engine power. The optimally placed water inlet minimises caking and makes the mixer almost self-cleaning. The easy-to-operate machine mixes all lime and cement-based ready-mix dry mortars up to a maximum of 4 mm. The compact LOTUS XS FC-230V fits into any estate car.
