G15/G40
Manual Air-Assist spray guns designed for
exceptional spray quality and ease of use.

Exceptional Spray Quality

Maximize efficiency and quality,
while reducing operator fatigue!
G15/G40 air-assist guns use the highest quality
components for long lasting reliable performance.
Most importantly, the G15/G40 guns deliver superior
spray performance while improving transfer efficiency
and reducing material usage.

Different Applications
Need Different Guns

G15/G40 guns have increased
durability and efficiency!
•	AAF tip line is designed for soft spray and
improved transfer efficiency
•	Longer-lasting needle packing – even with
abrasive materials
•	 More robust aircap retaining ring threads

G15 – 1500 psi models
designed for the wood
industry and other low
and medium pressure
applications

G40 – 4000 psi models
designed for high pressure
industrial applications

•	 All tips have a ring to retain the tip in the aircap
•	Easier removal of the integrated gun fluid filter –
no threads or tools needed
•	 G15 aircap indexing offers increased durability

G40 RAC – A 4000 psi
model designed with a
Reverse-A-Clean tip for
high pressure applications

Reliable Performance
Spray Quality
Achieve a Superior Finish
•	Enhanced tip design creates uniform atomization for a
superior finish quality
•	Unique aircap enables soft spray
•	Lower fluid and air pressure design allows for increased
transfer effciency
•	Adjustable fan pattern means less overspray, less material
waste, less VOC’s, and improved productivity

Merkur Air-Assist
Packages
High Performance Finishing
Quality pumps enhance any finishing system.
Paired with G15/G40 air-assist spray guns,
the Merkur fine finish packages are designed
to improve productivity, reduce costs, lower
emissions and provide consistent, high quality
finishes for all of your demanding applications.

High Quality Finish

Ergonomics
Maximize Productivity
•	Overall weight and gun balance is better than other spray
guns in its category
•	Trigger pull force is ultra-light – reducing operator fatigue and
muscle stress

Low pulsation output and smooth pump
changeover deliver a consistent spray pattern.

Easy-to-use
Easy-to-flush design allows for fast color changes
and reduced solvent usage.

Rugged Construction
300 Series stainless steel pump construction
provides long-lasting durability.

•	Handle design fits any size hand for increased operator
comfort

Cost of Ownership
Save Time and Money
•	Ease of assembly and disassembly reduces repair time
•	Designed to minimize wear of replacement parts
•	Fewer parts means an overall lower cost of repair
