1. What is the Purpose of your Spray Foam Rig?

The first step to take before selecting the best spray foam rig is to define the purpose of the rig.


In general, these are the basic categories of use which determine the rigs that will work for you:

  • Roofing/insulation
  • Part time/full time
  • Residential/commercial

Are you interested in insulation attics, storage tanks, or other application methods?

While it’s true that some rigs come pre-equipped, you can customize your spray foam rigs to fit your purpose.

If you’re a residential contractor or home builder that deals with applications which require average output of 5-8 PPM (pounds per minute) a machine with lower maximum output of 15-20 PPM is great – such as air driven machines.

If you work on both large residential and/or commercial projects and you invest most of your time on these projects, hydraulic machines with higher output ratings are ideal.

Do you intend to install spray foam roofing? With the introduction of robotics in the spray foam and coating markets accuracy and maximum production can be achieved with high-performance foam and coating machines.

2. Do you intend to spray both Foam and Coatings?

Another factor to consider is the specific material you’ll be spraying. Do you plan to spray only spray foam or do you have plans for coatings, slab jacking or pour foams?

For instance, if you’re working on your home, , an air driven closed-cell spray foam insulation rig is common and easy-to-use. These works ideally for small home renovation projects.

However, if you intend to spray several hundred or thousands of square feet, a more powerful hydraulic machine will work well for both coatings and spray foam. Whether you are a contractor wanting to install open cell foam or closed cell foam, they are both rated as a moisture barrier and serve as a higher R-value than fiberglass or rock wool. Those with lower R-value can retain moisture and lead to mold.

3. Do You Require High Pressure or Low Pressure Spray Foam Equipment?

The third most important stage in buying or choosing a spray foam insulation rigs is defining the kind of pressure your rig should have. This can change the requirements of space and equipment needed.

If you intend to spray foam only in a residential setting, you should select lower output spray foam equipment. However, for spraying coatings or spray foam in a non-residential setting where much more material is required, you need a higher output hydraulic machine with more hose length, pressure ratings and appropriate transfer pumps.

4. What Type of Trailer Do You Need?

Finally, you shouldn’t neglect your trailer type when planning to buy a spray foam rig. It’s essential that the rig you purchase can conveniently pull the loads in your trailer while supporting the demands of the intended use. Will the rig be used in the city where congestion is likely and space is a premium or will you be needing access in a more challenging geographical location where maximum payloads and extra rugged suspension is required?

If you perform a job where you carry mostly large loads, your rig should be customized to work for a goose-neck trailer, fifth wheel or box truck. Note that if you choose to buy used equipment, get the guarantee that it’s as efficient as the new one. Smaller loads can benefit from a box truck or shorter trailer.

  1. I am a general contractor in New York State, building custom homes. I want to install my own closed cell spray foam. I do 3-4 homes a year. Mostly two story. .
    I know how the system works. I am looking for a complete set up with proper trailer. I can provide trailer if we need to. I can buy cutters later. 250’-0 of hose should be fine. I like Graco products. We don’t need hydraulic applications as we are doing that kind of volume. ALS, do not need generators, as we generally have power in place long before spray foam and can tap. Into a 220 breaker. Llloking to purchase within next month.
