Electrostatic rotary atomizing spray device

The method of spraying a liquid coating material with an electrostatic rotary atomizing spray device, comprising the steps of:

• directing a flow of the liquid coating material through a fluid tube extending through the electrostatic rotary atomizing spray device;
• rotating a rotary atomizing head with an air turbine motor that produces an exhaust airflow;
• and
• directing at least a portion of the exhaust airflow from the air turbine motor through an air passage and then into the atomizer head to mix with the liquid coating material being dispensed by the atomizer head and to prevent the coating material from flowing into the air passage.

An electrostatic rotary atomizing spray device for spraying a liquid coating material, comprising:

• an atomizer housing which defines an interior chamber therein;
• a rotary drive shaft within the interior chamber of the atomizer housing, the rotary drive shaft being attached at a first end to a motor within the atomizer housing that produces exhaust air and at a second opposite end to a rotary atomizer head;
• a fluid tube being disposed within the atomizer housing for directing a flow of the liquid coating material to the atomizer head;
• and
• an air passage within the atomizer housing for directing at least a portion of the exhaust air through the interior of the atomizer head.

The method of spraying a liquid coating material with an electrostatic rotary atomizing spray device, comprising the steps of:

• directing a flow of the liquid coating material through a fluid tube within an atomizer housing and through an atomizer head to a forward flow surface of the atomizer head;
• rotating a drive shaft with a motor, that creates exhaust air, connected at one end to turn the atomizer head connected at a second end of the drive shaft;
• and
• directing at least a portion of the exhaust air from the atomizer housing through the atomizer head to mix with the liquid coating material.
