MINNEAPOLIS — Graco Inc., a manufacturer of fluid handling equipment, introduces Stellair ACE and Stellair, industrial air spray guns that have achieved an Ergonomics Performance Certification. Advanced testing by United States Ergonomics proves that manual pressure feed sprayers reduce fatigue potential, increasing productivity for industrial painters.

“Painting is really hard work,” said Peter Linder, vice president of North America sales and global product management for Graco’s Industrial Division. He is among the executives who worked a shift in a factory paint spray booth to better understand the needs of industrial painters.

“My shoulder especially hurt at the end of the day,” recalled Linder. “That experience drove home the need to champion a spray gun product line that painters will ask for because it adds to their wellbeing and makes the job of painting easier.”

While ergonomics was considered in previous spray gun designs, Graco recognized the importance of continual improvements by involving United States Ergonomics, a global ergonomic consulting service and product testing company.

The collaboration resulted in the industry’s first paint spray guns certified for ergonomic performance.

Stellair ACE weighs 7.4 ounces – up to fifty percent lighter than almost any other manual pressure feed spray gun – due to its durably unique carbon-reinforced polymer construction. Stellair ACE uses up to twenty-five percent less muscle effort than comparable industrial air spray guns.

Stellair, with aluminum metal construction, weighs 14.46 ounces, still making it among the lightest industrial spray guns available. Stellair lessens muscle exertion by up to eighteen percent compared to similar air spray guns. 

Reducing weight was not the only ergonomic advancement factored into the new spray gun design. Graco engineers also focused on minimizing hand pressure points, improving overall gun balance, and enhancing hose flexibility. Research and testing by United States Ergonomics allowed them to objectively measure the improvements.

United States Ergonomics researched and evaluated manual air spray gun ergonomics at three critical stages: design analysis and optimization; design review and testing; and ergonomic assessment. Each stage involved professional painters who work in industrial settings.

“Painters consistently rated the new Graco paint sprayers superior in weight, hand fit, feel, balance, trigger control, and adjustability,” said Kevin Costello, CPE, president of United States Ergonomics. “Their feedback was important to the Ergonomics Performance Certification. We expect field trials in production paint shop applications to fulfill formal certification requirements.”
