The GRACO 234390 is a compact air pressure regulator designed for precise control of air pressure in spray equipment. It is constructed with robust materials suitable for industrial environments and is intended to regulate air flow to ensure optimal performance of GRACO spray systems.

Key Features:

• Air pressure regulator with gauge
• Mini, 1/4 in. NPT(f) inlet and outlet
• 22 CFM at 50 psi
• Maximum inlet pressure: 160 psi (1.1 MPa, 11 bar); Regulated pressure range: 0–160 psi
• Compatible with GRACO spray equipment requiring 1/4 in. NPT(f) connections
• Self-relieving design for safety
• Compact size for easy integration
• Gauge for precise pressure monitoring
• Reliable diaphragm construction for consistent performance

Applications:
Used in industrial and commercial spray applications for paint, coatings, and other fluids where precise air pressure control is required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of spray equipment.
• Ensure main air line is at least 3/4 in. (19 mm) minimum, 1-1/4 in. (32 mm) optimum for best performance
• Install within 15–20 ft (4.6–6.1 m) of the spray equipment for optimal air delivery
• Follow all safety instructions and guidelines provided in the GRACO manual
