The GRACO 2004177 Stellair Air Conventional Spray Gun is a manual pressure feed spray gun designed for waterborne applications. It features a 0.055 in (1.4 mm) nozzle size with an SST tip, constructed for durability and precise atomization. The gun is intended for use in industrial and professional painting environments, delivering high-quality finishes with minimal maintenance.

Key Features:

• Conventional Air Spray Gun
• 0.055 in (1.4 mm) Nozzle Size, SST Tip
• Aluminum (gun body), SST (tip material)
• Maximum Air Inlet Pressure: 100 psi (0.7 MPa, 7 bar); Maximum Fluid Inlet Pressure: 300 psi (2.1 MPa, 21 bar)
• Waterborne applications, general industry, automotive, wood, high solids, adhesives, trim
• Lightweight and ergonomic design for reduced operator fatigue
• Durable construction for long service life
• Easy to use with quick color change and fast material refills
• Consistent spray pattern and uniform film thickness
• Low pulsation and smooth changeover

Applications:
Professional painting in general industry, automotive, wood, high solids, adhesives, trim, and waterborne applications. Suitable for both large-scale and small-scale operations.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with GRACO equipment.
• Set air pressure according to recommended starting pressures (for waterborne applications, typically 35 psi/0.24 MPa/2.4 bar)
• Test spray pattern at a consistent distance (6–8 in/150–200 mm) from the test piece
• Adjust fluid flow rate, input air pressure, and fan control valve for desired atomization and pattern size
• Use fluids and solvents compatible with equipment wetted parts
• Regularly inspect and maintain the spray gun for consistent performance
