ABSTRACT:
A high volume, low pressure air supply for a paint spraying system includes a primary, high pressure reservoir connected to a secondary reservoir maintained at a pressure substantially lower than the primary reservoir. The secondary reservoir is a "dedicated" unit supplying a limited number, for example two, conventional spray guns. The dedicated reservoir in combination with larger than conventional, short supply lines to the paint spray guns provides a high volume, low pressure spray system that results in substantially less "overspray" thereby conserving paint and reducing airborne pollutants. The air supply system includes an air heater downstream of the dedicated reservoir for heating air supplied thereby so as to reduce the viscosity of the paint entrained by the air stream.
