Manual Air-Assist spray guns designed for

exceptional spray quality and ease of use.

G15/G40

222

G15/G40 guns have increased

durability and efficiency!

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

G40 RAC – A 4000 psi

model designed with a

Reverse-A-Clean tip for

high pressure applications

Different Applications

Need Different Guns

• 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

• 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

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.

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

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.

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

• 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
