The GRACO 25C538 is a 15-gallon (58 L) pressure tank equipped with a radial piston air motor-driven agitator. It is designed for use in industrial and finishing applications to maintain consistent material mixing and supply under pressure. The tank is typically constructed from high-quality materials suitable for handling various coatings and finishes.

Key Features:

• Agitator with pressure tank
• 15 gallon (58 L)
• High-quality, precision-welded and surfaced; typically stainless steel or compatible material
• Maximum air inlet pressure: 100 psi (700 kPa)
• For use with low to medium viscosity materials (<1000 cp), suitable for wood (top coat, primer) and general finishing applications
• ASME rated (for pressure tanks, as per GRACO standards)
• Radial piston air motor-driven agitator for reliability and simplicity
• Operates at low to medium speed (<500 rpm)
• Uses less compressed air than most rotary vane air motors
• Quick installation and quiet operation
• Easy maintenance—air line lubrication not required
• Can be equipped with DataTrak for speed monitoring and over-speed alert
• Control speed with GRACO's Intelligent Paint Kitchen (IPK)
• Sound pressure level at 70 psig (max recommended speed): less than 75 dBA

Applications:
Used in industrial and finishing applications such as wood coatings (top coat, primer), general finishing, and as a material/catalyst supply or moisture-sensitive material reservoir in paint supply systems.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and safety in high-pressure applications.
• Ensure all connections are secure and rated for the maximum working pressure (100 psi/700 kPa)
• Follow GRACO’s installation guidelines for pressure tanks and agitators
• Regularly inspect for leaks and wear
• Use appropriate personal protective equipment during installation and maintenance
• Check agitator and tank for signs of wear or damage
• Clean tank and agitator components after use to prevent material buildup
• Monitor agitator speed and performance, especially when using DataTrak or IPK systems
