Munsch MA60

Munsch hand extruders are operated with either a separate compressor or an integrated blower for the air supply to the pre-heat air unit. With either, internal or external air supply systems, the pre-heat air temperature and extrude temperatures are separately set. The set point and actual temperatures are simultaneously read out on the extruder display. An interlock ensures that the drive can only be started when the pre-set temperature has been reached.
