A mobile spray foam rig is more than a trailer with tools—it’s a working jobsite on wheels. When you choose the right parts, you gain safety, speed, and professional results. From proportioners and air dryers to safety gear and add-ons, every piece plays an important role in daily performance.
Core Equipment for Every Mobile Spray Foam Rig
- Proportioner – The heart of the rig that mixes and delivers A and B materials on ratio for consistent foam.
- Air Dryer – A Tsunami Pure 5 air dryer removes moisture from air lines, which helps stop clogs and costly breakdowns.
- Heated Hoses – They keep material at the right temperature so spraying is smooth and even.
- Spray Gun – For example, the Fusion PC makes spraying simple while also allowing quick cleanups.
Power and Support Systems
- Compressor – A strong air compressor keeps spray guns and tools running without slowdowns.
- Generator – A diesel generator gives steady power to your proportioner, hoses, and support gear. As a result, your mobile spray foam rig can run all day without downtime.
- Transfer Pumps – These pumps move material from drums to your proportioner quickly and without clogging.
Safety and Operator Gear
- Fresh Air System – This system supplies clean air to applicators, which helps protect them from chemicals.
- PPE (Personal Protective Equipment) – Simple items like suits, gloves, goggles, and masks protect workers from harm.
- Ventilation Solutions – Good airflow is essential, and it makes jobs safer and more comfortable.
Additional Rig Accessories
- Material Storage – Racks and shelves keep drums secure during transport and keep supplies organized.
- Tool Kits – Having tools and spare parts on board means you can fix issues faster and reduce downtime.
- Lighting and Climate Control – Bright lighting and steady temperatures make work easier, no matter the weather.

FAQs
What size generator is best for a mobile spray foam rig?
Most rigs use a 30kW diesel generator. This size handles the proportioner, hose heat, and support tools without overloading.
Why is an air dryer important in a mobile spray foam rig?
An air dryer removes water from the air supply. Therefore, it prevents rust, clogs, and uneven foam.
Do all mobile spray foam rigs need a fresh air system?
Yes. A fresh air system is vital because it keeps workers safe by giving them clean air while spraying in tight areas.
