Air operated spray dispensers feed liquid to elevated, distant, or inaccessible points
The amount of liquid sprayed is infinitely adjustable from a fine spray, invisible to the eye, to a coarse spray by adjusting the air pressure of the needle valve on the spray nozzle
Any liquid that flows can usually be sprayed, up to 1000 SSU viscosity at 100°F
For best performance, a second regulator with suitable air capacity is supplied to adjust the air pressure to spray valves
Operation can be made automatic with two solenoid valves which can be activated by a motor drive or with a timer, allowing the valves to continually or momentarily apply a film of liquid
