What Equipment Do You Need for a Commercial Spray Foam Rig?

By Kevin Malone

The most important thing when investing in a commercial spray foam rig is to right-size the equipment to the type of job you want to do. While you do not want to overspend, you also do not want to show up for a job without the power and equipment needed to complete it.

Here are the key components that make up a spray foam rig. If you are not sure about the size or type of equipment you need, the spray foam experts at Intech Equipment & Supply can help you find the best solution.

Spray Foam Machine

The spray foam machine is the heart of your spray foam rig. Proportioning machines come in different sizes and capacities. You will need to get the right equipment depending on the type of jobs you handle. Some of the key components to evaluate include:

  • Drive system (electric, hydraulic, or pneumatic)
  • Output
  • Pressure capacity
  • Heating capacity
  • Electrical system

Intech Equipment & Supply stocks Graco and PMC proportioners / reactors for small, mid-size, and heavy-duty commercial spray foam jobs.


To operate your spray foam machine, you will need a reliable power source. A generator is generally used for commercial spray foam rigs.

Air Compressor

The air compressor provides the pressure you need to operate the spray foam machine, giving it the power to disburse the spray foam properly.

Heated Hose

You also need a heated hose to transport the chemicals from the spray foam machine to the spray gun. In commercial applications, the machine can be a distance from where the spraying occurs, so it is crucial to keep the spray foam materials at the proper temperature as they travel to the gun.

You will want to match the heated hoses to your specific spray foam machine. Every machine has maximum power ranges that are compatible with different hose lengths. If you are doing commercial roofing, for example, you could be hundreds of feet away from your commercial spray foam rig when spraying, so you need to make sure the hose and proportioner can manage the temperature. Less powerful proportioners might max out at 200 feet, while heavy-duty commercial units can generally extend to 400 feet.

Spray Foam Gun

The right spray foam gun for the project can make a significant difference. Many contractors have multiple spray foam guns for different task requirements or to keep operating when one gun needs cleaning or maintenance. You can also buy multiple nozzles.

There are three types of spray foam guns for SPF application including:

  • Mechanical purge
  • Air purge
  • Solvent purge

Some of the best spray foam guns are the market are made by PMC or Graco, providing highly-reliable and efficient operation.

Trailer or Truck

While stand-alone units are available, most contractors that do regular spray foam work opt for trailers or trucks to make transportation and management easier. This lets you take on the largest spray foam projects and makes it easy to move everything you need to do the job.

Several options are available in different sizes, including pull-behind trailers and box trucks. Both can be customized by the Intech Equipment & Supply team for a turnkey spray foam rig solution.

Other Equipment

One of the worst things that can happen is a breakdown in the middle of a job. A commercial spray foam rig will include cleaning equipment to keep everything working efficiently, replacement parts, and potentially backup generators or compressors.

You may also want to equip your spray foam rig with other items, such as equipment for power washing or abrasive blasting, before applying SPF.

You will also want any cleaning supplies, protective gear, fire extinguishers, a chemical eye wash station, and a first aid kit on board.
