The GRACO 289021 is a manual air spray gun designed for gravity feed operation, featuring a 0.070 inch (1.8 mm) nozzle and compatibility with 3M PPS cups. It is intended for precise delivery of light to medium viscous coatings in industrial and automotive applications. The gun is constructed with durable materials suitable for professional use.

Key Features:

• Manual air spray gun, gravity feed
• 0.070 inch (1.8 mm) nozzle
• 16–35 oz/min (0.47–1.04 L/min) for conventional guns with 0.070 inch nozzle (based on similar GRACO AirPro models)
• Maximum air inlet pressure: 100 psi (0.7 MPa, 7 bar); spraying pressure at air cap: 10 psi (0.07 MPa, 0.7 bar) for conventional guns
• 3M PPS cups, light to medium viscous coatings
• Precise spray delivery
• Prevents external contamination with 3M PPS cup
• Easy to maintain and clean
• Reliable performance for high-volume or custom shop environments

Applications:
Automotive, metal, wood, waterborne, high wear, adhesive, and other industrial liquid coating applications

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure all connections are secure and free from leaks before operation.
• Follow manufacturer guidelines for nozzle and air cap selection based on coating viscosity.
• Regularly clean and inspect the gun to maintain performance and prevent contamination.
• Use only compatible accessories such as 3M PPS cups for best results.
• Disassemble and clean the gun after each use.
• Inspect seals and O-rings for wear and replace as needed.
• Store the gun in a clean, dry environment.
