The
Graco Reactor 3 H-30 is designed for medium-to-high output spray foam and polyurea work in residential, commercial and OEM settings. The hydraulic platform integrates advanced features such as direct-drive pumps (eliminating belt and flywheel systems for quieter, reduced-maintenance operation), horizontal pump line for positive displacement performance, and a large touchscreen Advanced Display Module (ADM) that unifies control of spray operations, diagnostics and data logging. The system supports hoses up to 320 ft (≈97 m) and maintains full-flow performance through robust R3 hybrid heaters capable of 15 kW power. The Elite tier adds features such as independent hose A/B temperature control, oval-gear flow meters for real-time ratio monitoring, and cellular/GPS connectivity via Reactor Connect for
polyurea. With either the Pro (model 27R355) or Elite (model 27R357) version, you gain a comprehensive proportioner with impressive productivity, control and serviceability for serious
spray foam operations.
