According to the manufacturer, Flow International, the Paser 4 system is an efficient, integrated abrasive waterjet cutting system that is capable of unattended operation. The machine will either shut itself down or notify users in the case of abrasive waterjet failure.
A redesigned cutting head features a mixing chamber for efficient abrasive entrainment and extended orifice life.
Other features include an on/off valve, better cut quality, and an abrasive metering valve that is said to enable a more consistent garnet flow. An abrasive flow sensor is engineered to shut the system down in the event of a clog or if the machine runs out of abrasive. If there are overflow conditions, there is a sensor that will automatically shut the machine down should an unexpected event occur.
