1. A high volume low pressure (HVLP) turbine assembly, comprising:
a turbine assembly housing; a turbine disposed within the housing, the turbine comprising a turbine fan rotatable within a turbine casing, the turbine casing comprising a turbine air inlet and a turbine air outlet; a hose outlet fitting connected to the housing, the hose outlet fitting in airflow communication with the turbine air outlet, where the hose outlet fitting is configured to be connectable to an air hose for a spray gun; an electric motor mechanically coupled to the turbine fan and configured to rotate the turbine fan inside the turbine casing; a microcontroller disposed within the housing, where the microcontroller is electrically connected to the electric motor and controls a speed of the electric motor; a power input electrically coupled to the microcontroller; a pressure sensor in airflow communication with the turbine air outlet, where the pressure sensor is electrically connected to the microcontroller; an airflow sensing means electrically connected to the microcontroller; a timer electrically connected to the microcontroller; wherein the HVLP turbine assembly does not have a bleeder port in airflow communication with the turbine air outlet, where the bleeder port would be configured to exhaust outwardly; and wherein the microcontroller is configured to reduce the speed of the electric motor to an idle speed after a predetermined time has elapsed, wherein the predetermined time is started when the airflow sensing means indicates a period of inactivity. |
