Gas Spray Foam Rig Cost

Gas spray foam rigs are the most common entry point for new spray foam contractors. They use gas-powered generators and compressors to power air-driven proportioners — typically the Graco Reactor A-25 or similar platforms.

• A professionally engineered gas spray foam rig includes:
• Graco Reactor A-25 or equivalent proportioner
• 20 kW gas generator (matched to the A-25 heater package)
• 35 CFM gas compressor
• Refrigerated air dryer
• 160–210 ft heated hose system
• Fusion PC spray gun
• Complete safety package (supplied air for two workers)
• One day of hands-on training

A well-configured, production-ready gas rig from a credible dealer typically runs $75,000–$95,000.

Lower-priced gas rigs are available at $55,000–$70,000. At this price point, evaluate carefully what has been omitted or undersized. Common cost reductions include smaller generators, shorter hose packages, basic air filtration instead of a refrigerated dryer, and no or minimal safety equipment.

The SprayWorks 16-Foot Gas Spray Foam Rig is configured as a complete production system with properly matched components and includes a full safety package and training.
