Knauf PFT - LOTUS XL screw mixer

LOTUS XL The revolutionary mixing technique with decisive advantages.

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 LOTUS XL 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 significantly extends the service life of the wear part. The LOTUS XL 230V version is a silo mixer for grain sizes up to a maximum of 4 mm. The mixing capacity of the machine can be increased up to 90 l/min with special dosing shafts. Also available as 400 V version.
