Model A20A

nnnn

Automatic Electric Spray Gun

nnnn

Automatic, high-cycle electric spray gun for high-speed container

nnnn

coating applications.

nnnn

The patented Nordson® Model A20A automatic electric spray

nnnn

gun is a fast-cycle, airless gun designed for use in high-speed

nnnn

container coating applications. An advanced design of the

nnnn

industry-standard and production-proven Nordson Model A10A

nnnn

and A14A guns, the A20A gun features an integral solenoid

nnnn

that eliminates the need for air lines and provides fast, positive

nnnn

response and excellent repeatability. The removable-valve/seat

nnnn

module design facilitates easy replacement of the valve and seat

nnnn

assembly in minutes for minimal downtime without removing

nnnn

the gun from the spray machine or disconnecting hydraulic lines.

nnnn

All wetted components of the Model A20A gun are of stainless

nnnn

steel construction for improved durability and compatibility

nnnn

with a wide range of water-based and solvent-based lacquers.

nnnn

The A20A gun is triggered by electronic controls, such as a

nnnn

Nordson FET timer, for more precise film deposition, accurate

nnnn

weight control and greater material savings.

nnnn

Proprietary Nordson Nozzles

nnnn

The Model A20A gun uses Nordson Controlled-Pattern or

nnnn

Cross-Cut nozzles for precise coating deposition, uniform

nnnn

distribution of coating and consistent coating weights.

nnnn

Proprietary Cross-Cut nozzles improve atomization at lower

nnnn

operation pressure to minimize overspray and bounce back

nnnn

for optimum material utilization. Controlled-Pattern nozzles

nnnn

provide uniform coating distribution, resulting in lower coating

nnnn

weights and reduced costs. The A20A gun utilizes nozzles

nnnn

mounted directly on the short gun or extended version.

nnnn

Flow Sentry Option

nnnn

The Model A20A gun is compatible with the patented Nordson

nnnn

Flow Sentry® monitor. Installed with the gun or added later, this

nnnn

electronic system monitors the flow of coating material through

nnnn

the nozzle and automatically alerts the user to changes in flow

nnnn

caused by nozzle blockage, leakage or pump malfunctions. Use

nnnn

of the Flow Sentry option with the Model A20A gun further

nnnn

enhances the performance and quality of the can-coating

nnnn

operation, minimizing product rejects and providing optimum

nnnn

production quality.
