How Much Does a Spray Foam Rig Cost

The cost of a spray foam rig depends on three primary variables: the proportioner platform, the power system, and what is included in the turnkey configuration.

At the low end, spray foam equipment packages — machine, hose, and gun without a generator, compressor, trailer, or safety systems — start around $25,000–$45,000. These are not complete rigs. They are the spray components only.

A complete, production-ready gas spray foam rig with a properly matched generator, refrigerated air dryer, complete safety systems, and training runs $75,000–$95,000 for a well-engineered turnkey configuration.

A diesel spray foam rig with a hydraulic or electric proportioner, diesel generator, and complete systems typically runs $95,000–$130,000.

A digitally monitored rig with a Graco Reactor 3 or PMC Premiere platform, cellular connectivity, and complete systems typically runs $100,000–$160,000 depending on machine tier.

• What drives cost up:
• Higher heater wattage machine packages
• Diesel generator vs gas generator
• Longer hose systems
• Digital monitoring and cellular connectivity
• Larger trailer platforms
• Generator upgrades (40 kW, 50 kW vs 30 kW)
• Electric transfer pump packages

• What drives cost down (and what it means):
• Smaller generator (limits heater performance)
• No refrigerated air dryer (increases moisture-related problems)
• Shorter hose (limits jobsite reach)
• No safety systems (non-compliant for interior work)
• No training (increases risk of operator error)
