About Spraytech’s Automatic Spray Gun Nozzle Setup:

The PA Automatic Spray Gun range may be fitted with any of the air atomising spray set-ups listed. They allow on-off control of liquid spray by operation of an internal air operated piston, which can cycle at a rate of up to 100 cycles per minute.

Air control pressure is recommended to be 2.5 to 3 Bar (35 – 45 psi ; 250 – 300 kPa).

Connections are 1/4″BSP female for atomising air (A) and liquid (L); select one of two inlets 1/8″BSP female for air control. Operation is from the normally closed position.
