Dürr and HSM Lackiersysteme partnered to develop the EcoGun Ace, a low-pressure spray gun that makes color changes faster and easier. The spray gun features a rapid change system for the color channel — the spray gun is ready to use again within seconds after changing colors without solvents. This feature is well suited for the car repair sector, where small-batch painting is standard.

Like other Dürr low-pressure spray guns, the EcoGun Ace has a design well suited for industrial use. The company says it provides a spray pattern with distinctive application efficiency and simplifies color changing with quick-exchange injector nozzles. Additionally, a spill-proof cup system from HSM Lackiersysteme improves the product. The cup system incorporates a safety lock and soiling guard to promote good legibility of the measuring scales at all times.

Another feature of the spray gun is the rapid change system for the color channel, resulting in time and cost savings. The product is well suited for applications in various areas, such as woodworking, vehicle paintwork repairs, and yacht and boatbuilding applications.

Other feed cup spray guns are equipped with a cup that holds paint. When the time comes to change color, the cup must either be flushed and refilled or replaced with a new cup containing the appropriate color. In addition, all the channels that carry color between the cup and nozzle require flushing to prevent paint contamination or commingling. This process can be time-intensive and requires solvent use.

The EcoGun Ace spray gun features a system that enables much faster color changes. According to the company, the system replaces the entire color channel, including the nozzle, quickly and easily, so the spray gun is ready for use again within a few seconds, offering time savings of 90% compared with conventional low-pressure guns and making solvent use obsolete.

“In partnership with HSM, we are pleased to offer a very user-friendly product that sets new standards for low-pressure guns,” says Ulrich Tautz, senior sales manager of industrial products at Dürr. “Our spray guns will make painting easier, particularly for applications, such as woodworking or the car repair sector, where varnishing jobs with small amounts of varnish and lots of color changes are the norm.”
