2. Description

high-cycle, airless spray gun designed to spray solvent or waterborne
coatings. Because of its fast trigger cycle capability, the A7A gun may be
used for common product finishing as well as ultra-high speed
applications.
A7A guns are constructed of standard (aluminum) or stainless steel and
are available in both single- and dual-chamber models. The
dual-chamber models permit the user to quickly switch between two
different coatings or products with no downtime. You can also purchase
several special models such as high-speed, compound, valved
extension, and dual-chamber angled to fit your application needs.
Several service kits that may reduce downtime are available for
purchase. Retrofit kits that convert two single chamber A7A guns to one
dual-chamber model or to a dual-chamber angled model are also
available. Refer to the Parts section for details the part numbers needed
to purchase service and retrofit kits.
