Carlisle ST1 Spray Foam Gun Makes Spray Insulation Easier

By Kevin Malone

The Carlisle IntelliSpray System has been making waves in the spray foam industry since its official debut in 2020. Contractors are impressed with how easy the system is to use and how it sprays evenly. The Carlisle ST1 Spray Foam Gun in particular has been a crowd-pleaser with its outstanding design that brings a breath of fresh air to a task that is known to require much strength and endurance.

With a design that is inspired by the mannerisms and shape of the human body, the ST1 responds well to the contractor's need for comfort for long-term application. You can find the Carlisle ST1 Spray Foam Gun and other components of the IntelliSpray system at Intech Equipment & Supply.

Ergonomic Genius

Part of the Carlisle spray foam system, the ST1 was made for the hard-working contractor who does not quit when the conditions are tough. Determined to reach their goals, they stick to the task even when user fatigue sets in. The Carlisle ST1 Spray Foam Gun seeks to address these issues by making a better-designed gun for longer use. Everything from its size, weight, handle shape, and wings are manufactured for practical, comfortable use.

  • Size: It is a smaller gun than its competitors, which makes it easier to maneuver. The specific dimensions are 74mm x 166mm x 196mm.
  • Weight: The ST1 is just 2.38 pounds without the manifold, making it the lightest air purge gun in its class.
  • Balance: The award-winning balanced handle makes it easier to handle, and is more compact than competing models. Also, the top of the handle has flared surfaces to further relieve pressure on the user's hand.
  • Optional safety strap: This thoughtful addition allows users to rest their hands for a few moments to prevent cramping.

Requiring steadiness and stable movements, a quality application of spray foam depends much on how the user handles the spray foam gun. The Carlisle ST1 Spray Foam Gun is easier to hold and maneuver, which naturally yields better results.

Addressing User Complaints and Needs

The Carlisle spray foam system approaches SPF technology from the user's perspective, targeting the top wishes and resolving the most common complaints. The Carlisle ST1 Spray Foam Gun is a vital IntelliSpray component that addresses the three main issues spray operators face:

  • Too much downtime
  • Sprayer fatigue
  • Pattern inconsistency

As a result, the light, ergonomic design and modern features promote consistent spray patterns and less user fatigue. Both big and small details were addressed, making the Carlisle ST1 Spray Foam Gun a highly efficient gun that avoids the downtime that happens with other competing air purge guns.

For instance, the check valve prevents material and fluid from entering the air passage, which in turn prevents malfunctions. The tips can be easily and quickly changed so operators can alter spray patterns and flow. The gun, which is coated with Ultra Onyx, has a high-performance side seal that prolongs the gun's life and makes it easier to clean.

Thoughtfully Designed

The Carlisle ST1 spray foam gun has also won awards. In 2020, its prototype won first place in the hardware, power, and hand tools design category in the A Design Award Competition. This gun is inspired by human anatomy ? in particular, the shape of the human hand and how it grasps a handle. Therefore, the handle is one of the most comfortable and supportive in its class. This comfort makes it easier to deliver consistent spray patterns so that the results are always professional.

The finest details were under the utmost scrutiny in the design process. For example, the rear cap, which is typically disassembled with a pipe wrench, has small indentations so that it can be tightened by hand. Aesthetics were also a priority, and Carlisle did not settle for anything less than a supplier that was able to laser-engrave the rotated overwrap graphics through the hard exterior coat.

Overall, it was designed to be comfortable for contractors who work long hours in challenging conditions, such as hot temperatures or tight areas. Spray foam insulation is used in jobs of all scales, so the ability to adapt to difficult environments is necessary for widespread appeal.
