  "abstract": "Systems for conveying granulated materials from a material source include a receiver in fluid communication with a material source, a vacuum generator or a pump unit having a blower configured to generate a vacuum or a pressurized airflow that transports the granulated material to the receiver from the material source, and a combination relief and break valve located in the flow path between the blower and the receiver. The valve is configured to interrupt the vacuum or the pressurized airflow provided to the receiver when the vacuum level or the positive pressure level reaches a relief set point. An electronic control unit of the system is configured to automatically adjust the relief set point based on one or more predetermined criteria. The vacuum generator or the pump unit can include an IPM-SynRM motor, IPMSM motor, or a PMSM motor that drives the blower of the impeller in rotation.",
