Graco Reactor 3

Upgrade your spray foam or polyurea setup with the Graco Reactor 3, the newest generation of proportioning technology built for precision, consistency, and efficiency. As the most advanced model in Graco's lineup, Reactor 3 introduces fully connected "drum-to-gun" communication. This innovation synchronizes material supply, pressure, and temperature to deliver perfect on-ratio performance every time. Whether you're spraying insulation, coatings, or elastomers, this system helps you work faster, smarter, and with greater confidence on every job.

The Reactor 3 is engineered to make every part of the spray process more predictable and efficient. With integrated electronic pressure control and touchscreen operation, setup and adjustments are simplified, while real-time system feedback keeps your material ratios perfectly balanced. Each component from pump to hose to gun communicates through Graco's advanced control platform to maintain on-ratio accuracy and consistent spray patterns. The result: better yield, fewer re-coats, and a higher-quality finish that minimizes waste and material costs.

Every feature of the Graco Reactor 3 improves uptime and profitability. The new lightweight frame, direct-drive pump, and simplified hydraulic or electric configurations mean faster start-ups and less maintenance downtime. A redesigned layout reduces generator and compressor requirements, helping lower operating costs for rig-based operations and mobile spray crews. Remote monitoring and job reporting make it easy to track performance and share data with your team, so you spend more time spraying and less time troubleshooting.

If you're searching for Graco spray foam proportioners that deliver unmatched precision and connectivity, the Reactor 3 represents the new standard for professional-grade performance in the field.
