Description

The Graco GX-7 Spray Polyurea Gun (Model 7-400) is engineered for high-performance applications requiring precision and speed. Its shorter stroke length ensures rapid material processing, making it ideal for fast-setting polyureas. The gun features a fan spray pattern, with a 16-inch width at 18 inches from the target, and a pattern control knob for fine-tuning. It offers a mechanical-purge system, eliminating the need for costly solvent flushing. The lightweight design (4.1 lbs) reduces operator fatigue, and the air cap facilitates easy cleaning of the purge rod. Compatible with materials like polyurea, polyurethane, elastomeric coatings, and spray foam, it supports a maximum fluid pressure of 3500 psi and a maximum flow rate of 8 lb/min. The gun includes a mix module and tip, with a 1/2-20 UNF Component A inlet and a 9/16 UNF Component B inlet. Its mechanical-purge mechanism ensures efficient operation without the need for solvents.
