Choosing the right Graco spray foam rig involves more than comparing the proportioner alone. Contractors also need to consider power, air supply, heated hose capacity, material handling, trailer layout, and the way every component works together on the job.
The ProPAK 300D with the Graco Reactor 3 E-30 Pro brings those systems together in a diesel-powered setup designed for professional insulation contractors who need dependable production and room to grow.
What Is Inside the ProPAK 300D?
The ProPAK 300D is built in an 8.5 x 20-foot, 14,000-pound GVWR tag-along trailer with a side door and two rear barn doors. Its layout provides space for more than three sets of spray foam material while still leaving room for equipment, ladders, scaffolding, safety supplies, and other jobsite essentials.
Major components include:
• Graco Reactor 3 E-30 Pro with a 10kW heater
• 220 feet of internally heated hose
• Graco Fusion PC spray gun
• Two Graco T3 transfer pumps
• 30kW diesel generator
• 5 HP electric air compressor
• 40 CFM Pure 10 air dryer
• Double-worker supplied-air system with 200 feet of hose and two full-face masks
• Rooftop air conditioning and wall heater
• ProPAK interior package
When evaluating your next Graco spray foam rig, looking at the complete system is important. Each component needs to support the production demands of the proportioner rather than simply being installed alongside it.
Graco Reactor 3 E-30 Pro Performance
At the center of this Graco spray foam rig is the Reactor 3 E-30 Pro. The E-30 platform can provide material output of up to 30 pounds per minute and can support up to 310 feet of hose depending on the configuration.
For contractors, that production capability can support a wide range of residential and commercial insulation applications. The ProPAK 300D is designed for both open-cell and closed-cell spray foam and can also support certain spray foam roofing applications.
However, maximum output should not be the only consideration. Contractors should compare expected job sizes, crew production goals, material requirements, hose distance, and application type before choosing a proportioner.
Look at the Entire Power System
A proportioner can only perform properly when the rig’s electrical system can support it.
The ProPAK 300D pairs the Reactor 3 E-30 Pro with a 30kW diesel generator. This creates a self-contained power source so crews are not dependent on available shore power at each jobsite.
When comparing another Graco spray foam rig, contractors should consider:
• Generator capacity
• Proportioner heater requirements
• Compressor power requirements
• Additional electrical loads inside the trailer
• Available reserve capacity for normal operation
A properly matched power system helps the equipment operate as a complete package rather than forcing crews to manage electrical limitations in the field.
Air Supply Matters Too
Compressed air supports several important functions inside a spray foam rig. Therefore, contractors should look closely at both the compressor and the air-drying system.
The ProPAK 300D includes a 5 HP electric compressor along with a 40 CFM Pure 10 air dryer.
Dry, consistent compressed air helps support the spray gun and other pneumatic equipment. In addition, contractors should consider the number of air-powered tools they expect to operate and whether the air system can keep up with normal production.
Heated Hose Length and Jobsite Reach
Hose length directly affects how crews move around a project.
The ProPAK 300D includes 220 feet of internally heated hose as configured on the current SFS package. The Reactor 3 E-30 platform can accommodate additional hose capacity depending on the system configuration.
A longer hose setup can reduce the need to reposition the trailer during larger projects. However, contractors should choose hose length based on the type of work they actually perform rather than simply selecting the longest available option.
Material Supply and Transfer Pumps
Reliable material delivery is another major factor when selecting a Graco spray foam rig.
The ProPAK 300D includes two Graco T3 transfer pumps to move ISO and resin from the material drums to the proportioner.
Contractors should examine how easily drums can be loaded, connected, changed, and monitored. An organized material area can make day-to-day operation easier while helping crews maintain a more efficient workflow.
Consider the Spray Gun
The proportioner may create the pressure and heat, but the spray gun is where the material finally reaches the application surface.
The ProPAK 300D includes a Graco Fusion PC gun.
When comparing rigs, contractors should consider gun familiarity, replacement parts availability, maintenance requirements, and whether their technicians already know how to service the gun being supplied.
Trailer Layout Can Affect Daily Productivity
Equipment specifications matter, but layout matters too.
A well-designed Graco spray foam rig should give technicians reasonable access to the proportioner, transfer pumps, filters, air equipment, electrical components, drums, tools, and service points.
The ProPAK 300D‘s 20-foot trailer also provides additional storage space for jobsite equipment and material. That extra room can be especially valuable for contractors who carry ladders, scaffolding, PPE, spare parts, and other supplies between projects.
Think Beyond the Equipment List
Two rigs may contain similar components and still operate very differently in the field.
Before buying your next Graco spray foam rig, consider how the complete package supports:
• Your typical project size
• Required material output
• Open-cell versus closed-cell applications
• Roofing work, if applicable
• Hose distance
• Crew size
• Material storage
• Generator and air requirements
• Equipment access and maintenance
• Future business growth
The goal should be a system that matches how your crew actually works rather than choosing equipment based on one specification alone.
Why Consider the ProPAK 300D R3 E-30 Pro?
The ProPAK 300D combines the production capability of the Graco Reactor 3 E-30 Pro with the power, air, hose, material-handling, safety, and storage systems contractors need in a turnkey mobile package.
For contractors comparing their next Graco spray foam rig, the ProPAK 300D offers a strong middle ground between entry-level equipment and larger high-output systems. It can support contractors entering professional spray foam production as well as established businesses adding another rig to their fleet.
Compare your production requirements, application needs, hose length, power requirements, and crew workflow with the ProPAK 300D to determine whether it is the right spray foam rig for your operation.
