Electric spray gun for container coatings with
ultra high-speed response and high accuracy.
MEG
®
II Spray Gun
The Nordson MEG
®
II spray gun provides the fast, accurate
application of solventborne and waterborne can lacquers for
two- and three-piece containers. The MEG II gun is also ideal
for exterior bottom-spray applications.
Fast Response Time, Reliable Operation
Consistent, repeatable and fast open and close times provide
more full-open time for each spray cycle. This allows for faster
operating speeds when desired, as well as lower operating
pressures for less bounceback of applied coating. The gun’s
repeatability provides more consistent spray weights, reduced
material waste and cleaner operation.
The MEG II compact spray gun has no internal metal-to-metal
friction points, contributing to a faster response time and
reducing wear and heat generation in the gun. The coil and
armature assembly is specially designed to create less heat
than other electric guns for reliable operation and longer wear
of the parts. The overall cooler operation of the gun reduces
film build-up inside the gun and minimizes valve sticking.
Ease of Maintenance and Repair
The ball-and-seat assembly is designed to minimize wear, which
greatly extends the product life of the gun. When repairs are
needed, the gun module can be replaced on-line for minimal
downtime. The gun body has been designed with “flats” to grab
with a wrench for easier maintenance, and the seat holder has
an indexing ability so the seat can be rotated to promote uniform
wear on the contact points of the coil face. Altogether the gun
contains few moving parts to simplify rebuilding and minimize
replacement-part inventories.
With traditional beer and
beverage waterborne lacquers,
the MEG II gun coupled with a
Nordson driver opens in less
than 2 milliseconds (2.5 times
faster than standard guns) and
closes in less than 2 milliseconds
(4 times faster than the industry
average).
Features and Benefits
• Fast response provides more open time for each spray
cycle, which allows:
—
Faster operating speeds when desired
—
Lower operating pressures, generating less bounceback
of applied coating
• Repeatability provides more consistent spray weights,
reduced material waste and cleaner operation
• Cool operation contributes to the fast response time
and minimizes film build-up inside the gun, reducing
maintenance
• No internal metal-to-metal friction provides less wear,
longer service life and cooler operation
• Online gun-module replacement speeds maintenance.
• Nozzle pattern adjustments can be made while the
gun is spraying for fast, accurate adjustment

Why choose Nordson
In highly competitive manufacturing markets, productivity is
vital and performance is essential. That’s why we apply both
to everything we do, whether it’s our products, expertise
or outstanding customer service. We’ll always be there to
help maintain the new standards you’ve set, with expert
service and support delivered through our teams working
across the globe.
This unique Nordson approach helps you reach new levels
of production, while working more accurately, efficiently and
competitively than ever. Precisely why manufacturers who
demand quality, can rely on Nordson.
The semi-captured nozzle o-ring provides a reliable seal.
The gun spray-end design holds the seat assembly from
twisting when installing or removing a nozzle. This speeds
installation and guards against damage to the gun caused
by over-tightening of the nozzle nut.
Integration into Nordson’s Best
Practice System
The MEG II gun provides easy addition of the Nordson
CleanSpray® Automated Nozzle-Cleaning System.
Automated nozzle cleaning reduces manual nozzle
cleaning to as little as once per shift, which reduces labor,
increases productivity and improves coating quality.
The MEG II gun is also compatible with the Nordson iTrax
®
System. Installed with the gun or added later, this system
monitors the flow of coating material through the nozzle
and controls important operating parameters. This offers
enhanced product performance and quality of the can coating
operation to minimize rejects and optimize production quality.
Spray Gun Drivers
Operation of the MEG II gun is controlled by either the NC-1
Driver or the iTrax Spray Controller, both of which provide a
current-controlled signal to the gun. To speed gun response
time, the drivers deliver a higher turn-on current pulse for
three milliseconds, followed by a lower holding current for
the duration of the period. This minimizes the amount of
energy stored in the gun and results in a fast turn-off time.
Both drivers provide a precise and consistent gun drive
signal and require no adjustments.
The drivers operate at speeds above 3,000 cycles per minute
and are available in single and dual channel modes.
