A7A automatic guns are compact, high-cycle, airless spray guns designed
for use with solvent or waterborne coatings. They are air-operated,
actuated by remote electro-pneumatic solenoids. They can be used for
general finishing as well as ultra-high speed applications.
A7A guns are available in single-chamber, straight dual-chamber and
angled dual chamber models. The dual-chamber models permit the user to
quickly switch between two different coatings with no downtime. Kits are
available to convert two single-chamber A7A guns to one straight or angled
dual-chamber gun, or a straight dual-chamber gun to an angled gun.
Refer to the A7A Gun List on page 14 for a list of all available models.
