The Graco Reactor H50 Spray Foam Proportioner is a high-output hydraulic spray foam machine delivering up to 52 lb/min with precise temperature and pressure control, making it ideal for large-scale professional insulation and roofing applications.
The
Graco Reactor H50 Spray Foam Proportioner is a high-output, hydraulic, heated plural-component system engineered for demanding professional spray foam applications. Designed for continuous spraying of polyurethane foam, the Graco Reactor H50
Spray Foam Proportioner delivers up to 52 lb/min (24 kg/min) at 60 Hz, making it ideal for large commercial, roofing, and industrial insulation projects. A hydraulic drive system provides smooth pressure control and consistent material delivery, while precision A- and B-side heaters maintain stable fluid temperatures up to 190°F (88°C).
The Graco Reactor H50
Spray Foam Proportioner features an integrated temperature and pressure monitoring system with built-in diagnostics to protect against pressure imbalance, overheating, and communication faults. Multiple electrical configurations allow operation in single- or three-phase power environments, and high-capacity heaters support long heated hose lengths for extended reach on large job sites. Built with durable industrial components, the H50 is optimized for reliability, serviceability, and high-production spray foam operations.
