Why compressed air?
Why does the press have a compressed air connection or an accumulator?
The compressed air retracts the ram back to the TDC (top dead center) with constant force and speed. In addition, the speed can be individually adjusted with the pressure regulator, this pneumatic driven return stroke increases the ergonomic compared to a conventional spring solution. In addition, the two-chamber design of the accumulator ensures that the weight of the upper tool can be compensated via the adjustable differential pressure.
The version with pressure accumulator is available for self-sufficient and maximum energy-efficient operation of the press. Thanks to the intelligent re-storage of compressed air, the loss of compressed air is minimised and it is sufficient to fill the accumulator about once a week. Alternatively, the press can also be connected directly to the compressed air supply.
