Erweka* AR 403
The ERWEKA All-Purpose system is based on a powerful drive unit available in two versions. The various attachments can be easily and quickly connected by means of a coupling.
The drive unit AR 403 is equipped with a three-phase AC motor. The sturdy ball bearing worm gear drive is completely maintenance free and provides an output torque of max. 23 Nm. The unit features electronic speed control, variable between 20 and 400 rpm. A digital dial regulates the speed.
Through permanent nominal/actual adjustment the preselected speed is kept, even under varying load. The AR 403-S is similar to the AR 403, but has a different drive train. This connection is designed for heavy use.
