Graco's Polyurea Air-Purge Spray Gun Offers Tool-Less Maintenance

Monday, December 23, 2002
A key consideration for users who spray fast-set plural-components materials, such as polyurea, is gun maintenance. Graco Inc. makes quick and easy maintenance a reality with the Fusion plural-component air-purge spray gun. Designed specifically for polyurea, sprayers can easily disassemble and clean the Fusion AP without any tools, ensuring proper material application and productive uptime.

"Due to its short reaction time, polyurea causes guns to clog easily, forcing sprayers to spend a significant amount of time on maintenance," said Brian Zumbolo, worldwide product marketing manager, Protective Coatings Equipment, Graco.

The Fusion's adjustable tip air-blast cleaning feature reduces tip clogging and downtime. In addition, the Quick-shot grease port shortens end-of-day maintenance time and eliminates the need to take the gun apart for cleaning. When spraying coatings for extended periods of time, operator fatigue is a risk. The lightweight, ergonomic design of the Fusion reduces this risk, while the four-position fluid manifold and two-position air-power inlet provide application flexibility and comfort.

Graco designed the Fusion to withstand harsh application demands. Durable hardened stainless steel construction gives mix chambers and seals 50 percent longer life than comparable products, which translate into lower operating costs. Graco estimates that users can expect a return on the Fusion investment in less than six months.

The Fusion gun is designed for use with the Graco Reactor plural-component proportioning system. The Reactor's digital controls and diagnostics are easy to use, providing superior mix accuracy in a lightweight, highly portable design.

Graco's Polyurea-Dedicated Proportioner

Since polyurea's inception, contractors and material suppliers have been limited to applying it with modified foam-spraying equipment, which is not optimized for polyurea applications. To meet the high-temperature, high-pressure demands of polyurea applications, Gracohas announced the Reactor E-XP, the first polyurea-dedicated proportioner. Built-in diagnostics provide ratio assurance, easing operator use, and its lightweight design gives users unprecedented job-site mobility.

"The Reactor is the next generation of polyurea delivery systems," said Joe Haydu, vice president of field services, VersaFlex. "Graco created a proportioner with a compact and functional design with a smooth, consistent electric pump that keeps pressures within 50 psi."

The Reactor's easy-to-use controls and integrated monitoring capabilities take the guesswork out of polyurea applications. Featuring Graco Smart Mix controls, the Reactor provides operators system diagnostics, auto shutdown and data reporting. Its digital controls and improved temperature-sensing capabilities provide accurate heating. Digital pressure control, reduced pulsation, improved pump loading and balanced feed pressures make the Reactor the ultimate polyurea metering system. The improved application controls result in ratio assurance, superior mix accuracy and, ultimately, better quality.
