What To Look for When Choosing a New Spray Foam Rig

Before you start a spray foam business, you’ll need to select a spray foam rig. That can be easier said than done, as many factors should go into your decision. Additionally, a wide variety of options are currently on the market; you’ll need to choose the configuration of your trailer, the generator size, and more. Since there’s much to consider when picking out a rig, we’ve prepared a guide for you to follow.

What Will You Use It for the Most?

Of course, if you don’t know what to look for when choosing a new spray foam rig, you need to think about its use first. Ask yourself what types of jobs you’re going to use your rig for the most. Do you specialize in industrial work, spraying large roofs and intricate air barriers? Or will you be knocking out residential contracting jobs? Knowing this will help you determine what type of rig you need.

Selecting a Generator Size

When you purchase a spray foam rig, you get to determine the size of your air compressor and generator. With so much freedom, it can be challenging to know what size is optimal for you. A good rule of thumb is always to go bigger when in doubt. After all, you don’t want to get stuck without enough power to operate your rig.

Luckily, there’s a tried-and-true formula you can use to select your generator size. List out all the components that you have and their peak watt requirements. Total up the wattage and multiply it by 1.25. That will determine the kVA or kilovolt amperes. From there, all you must do is select a generator that’s equal to or greater than your kVA.

Pick a Spray Foam Gun

Of course, you need a high-quality spray foam gun to apply your insulation. If you buy used equipment, always check the foam gun for hardened materials. In fact, this is a good rule of thumb, even for new units—you want to make sure that your spray foam gun is completely clean. The different types of spray foam guns are as follows:

  • Air purge guns are the most popular. They use compressed air to clean the chamber, and they’re easy to maintain.
  • Solvent purge guns eliminate the need to drill the mixing chamber. It also uses far less air than an air purge gun.
  • Mechanical purge guns are rugged and have the broadest range of flow rates.

Select Your Trailer Configuration

For your trailer, there are two configurations available. They include:

  • Standard. A standard trailer works with any type of truck. It has a decent carrying capacity, but not as much as a gooseneck style.
  • Gooseneck. You’ll get more carrying capacity, but you sacrifice mobility—in other words, they’re more challenging to maneuver. That’s why these trailers need special trucks that can handle the fifth wheel.
