What is a Mobile Spray Foam Rig?

A spray foam rig is a mobile unit composed of various equipment necessary for spray foam insulation projects. These rigs typically include components such as a proportioner, Air Compressor, Air Dryer, Generator, and Transfer Pumps. The combination of these elements creates a self-contained system that allows you to transport and operate all the necessary equipment conveniently.

Mobile Spray Foam Rigs: Equipments & Materials Explained

Foam Rig Generators: These are used to power the various components of the spray foam rig, such as the proportioner and Compressor.

Foam Rig Compressors: Compressors provide the necessary air pressure for the spray foam application process.

Spray Foam Rig Air Dryers: Air dryers remove moisture from the compressed air to ensure optimal performance of the spray foam system.

Safety Supply and Mechanics Station: This station includes safety equipment such as gloves, goggles, and respiratory protection, as well as tools for maintenance and repairs.

Spray Foam Rig Drum Station: The drum station is used to hold and organize the drums of spray foam material.

Spray Foam Rig Drum Blankets: Drum blankets help maintain the proper temperature of the spray foam material, ensuring optimal performance during application.

Spray Foam Rig Transfer Pumps: These pumps are responsible for transferring the spray foam material from the drums to the proportioner.

Spray Foam Machine: The heart of the spray foam rig, the machine or proportioner, heats, pressurizes, and provides the correct ratio of the two components of the spray foam material and pumps it to the spray gun.

Heated Spray Hoses: Heated hoses keep the spray foam material at the desired temperature as it travels from the proportioner to the spray gun.

2-Spray Foam Gun: The spray guns are used to mix and apply the spray foam material onto the desired surface.

It's important to note that the specific spray foam equipment included in a spray foam rig may vary depending on the manufacturer and the requirements of the project. It's essential to choose a rig that suits your specific needs and consult with experts in the field for guidance.

Expert Advice on Spray Foam Equipment


Before starting any spray foam project, ensure that your rig is in good working condition. Check the proportioner for proper pressure and temperature settings. Make sure the Air Compressor and Generator are operational. Inspect the Transfer Pumps for any leaks or malfunctions.

2. Material Setup:

Load the required spray foam insulation material into the rig's designated compartments. Ensure that the material is at the proper temperature and ready for application.

3. Safety Measures:

Prioritize safety by wearing the appropriate personal protective equipment (PPE), including gloves, goggles, and respiratory protection. Familiarize yourself with the safety protocols for spray foam insulation to prevent any accidents or health risks.

4. Spray Application:

Follow the proper start up procedure for the generator, compressor, proportioner and spray gun. Start spraying the foam onto the desired surface, maintaining a consistent distance from the substrate for even coverage.

5. Monitoring Equipment:

Throughout the application process, keep an eye on the pressure and temperature gauges of the proportioner. Make necessary adjustments to maintain optimal conditions for spraying.

6. Clean-Up:

After completing the spray foam insulation application, follow the proper shut down procedures and clean the spray gun if necessary. Follow the manufacturer's guidelines for proper cleaning procedures.
