Carlisle ST1 Air Purge Spray Foam Gun

The Carlisle ST1 Air Purge Spray Foam Gun combines lightweight construction with modular serviceability for reliable performance on spray foam and polyurea applications. Designed with ergonomic features and durable components, this gun handles continuous use while giving operators better control and reduced hand fatigue during extended work periods.

Key Features

The ST1 delivers operator-focused design improvements that translate directly to jobsite performance:

• Ergonomic design: The wing-style handle and swivel hand strap distribute weight from fingers to arm, reducing operator fatigue during long spray sessions.
• Lightweight construction: It weighs 10% less than comparable spray foam guns, enabling work in overhead or tight-access areas with less strain.
• Modular serviceability: All components are accessible with a single tool for quick field repairs and minimal downtime.
• Interchangeable chambers: Swap mix chambers and tips on-site to adjust flow rates and pattern widths without returning to the shop.
• Ultra Onyx coating: This protects the gun body from chemical erosion and simplifies cleaning between applications.

Built for Spray Foam Contractors

The air purge design prevents material crossover in the air passage, maintaining consistent spray patterns throughout the workday. High-performance side seals extend operational life and reduce seal failures that cause unplanned downtime. The trigger mechanism allows operators to rest their grip between passes without repositioning the entire gun.
