The GRACO 224486 is a corrosion-resistant, low shear fluid back pressure regulator designed for use in circulating air spray systems. It features stainless steel (SST), acetal, and PTFE wetted parts, ensuring compatibility with water-based fluids and resistance to corrosion. Its primary function is to provide regulated back pressure to spray guns and maintain proper circulating pressure throughout the system.

Key Features:

• Back Pressure Regulator
• Model 224486, Series B
• Stainless steel (SST), acetal, and PTFE wetted parts
• Minimum fluid flowrate: 4 GPM (15 L/min)
• Maximum working pressure: 300 psi (2.1 MPa, 21 bar); Regulated pressure range: 15 to 200 psi (0.03 to 1.4 MPa, 0.3 to 14 bar)
• For use with water-based fluids in circulating air spray systems
• Low shear design minimizes paint degradation
• Corrosion-resistant materials for long service life
• Includes gauge port for pressure monitoring
• Designed for easy integration into existing systems

Applications:
Used in industrial finishing processes where consistent paint quality and system pressure are required, particularly in circulating air spray systems for water-based coatings.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Read all instruction manuals, tags, and labels before operating the equipment
• Ensure proper alignment and secure connection of inlet and outlet fittings
• Use appropriate tools and follow recommended torque specifications for fittings
• Regularly inspect for leaks and wear, and maintain as per manufacturer guidelines
• Periodically check and clean wetted parts to prevent buildup
• Monitor pressure gauges for consistent performance
• Replace worn or damaged components with genuine GRACO parts
