The GRACO 1-6770-3 KIT is a membrane air dryer designed to remove uncondensed moisture from compressed air systems. It is engineered for heavy-duty performance and is typically constructed from robust materials suitable for industrial environments. Its intended use is to ensure dry, contaminant-free air for GRACO equipment, particularly in applications where moisture can affect performance or product quality.

Key Features:

• Membrane Air Dryer
• 1-6770-3
• 30 cfm (0.85 m³/min)
• Max. Operating Pressure: 175 psi (1.2 MPa, 12 bar)
• Designed for use with GRACO compressed air systems and compatible with 1/2 in. F.P.T. piping
• Point-of-use air dryer
• No electricity required
• No maintenance required for Stage 3 (membrane dryer)
• No chemicals to dispose of
• Continuous, effective air drying
• Easy installation
• Transparent operation
• Effective even at low flow rates

Applications:
Used in industrial and shop environments to provide dry, clean compressed air for painting, lubrication, and other processes where moisture control is critical.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety of the air drying system.
• Install the air drying system as close as possible to the point where the air is being used.
• Install a main shut-off valve upstream of the air system to allow for maintenance.
• Ensure air flows through filters in the direction noted on the units.
• Use minimum 1/2 in. NPT piping and avoid excessive fittings or couplings that restrict air flow.
• Relieve pressure before cleaning, checking, or servicing equipment.
• For overnight drain operation, turn off air pressure.
