EWL 5837

A 1 Features

KaVo EWL vacuum mixers serve not only for the mixing of all types of plaster, investment materials and silicones, but also for special
techniques in dental technology such as the hydration of models.
They are provided with separate drive systems for generation of vacuum, and the stirring mechanism.  The stirring mechanism can be
switched on and off by a time-controller at any time, without disturbing the vacuum.
The pre-set mixing time of up to 240 seconds is set only once, and remains available for further mixing procedures. The end of the stirring
time is indicated by an acoustic signal.
As the mixing bowl of the unit is held by vacuum at the flange, total vacuum is guaranteed.
On delivery, the units are prepared for wall-mounting, but can be converted for bench-mounting at any time. (see Accessories)
