The QBZ2-2x120/1140(660) mining explosion proof partial ventilator combination vacuum electromagnet starter (hereafter called Starter) applies to mines that are full of dangerous gas (methane) and coal dust. The rated voltage is 1140V or 660V and starter can be used to control and protect several counter rotating partial ventilators' combinational operation, so that it can ensure the heading face's continual ventilation and reduce unplanned stop ventilation events.
