The GRACO Dryaire Membrane System is an advanced air drying system designed to remove moisture, oil, and sub-micron particles from compressed air. It is constructed for shop use and is ideal for protecting moisture-sensitive tools and applications such as waterborne paint systems. The system is lightweight, easy to install, and simple to operate.

Key Features:

• Membrane air drying system
• 6770
• 30–115 CFM depending on configuration (commonly 30 CFM at 175 psi for standard shop use, up to 115 CFM for higher capacity models)
• Max. 175 psi (1.2 MPa, 12 bar)
• Compatible with standard compressed air systems and paint booth setups
• Maintains –40°F dew point
• Achieves 0% compressed air humidity
• Removes oil and sub-micron particles down to 0.01 micron
• Maintenance-free (no desiccant or refrigerant to replace)
• Lightweight and easy to install
• Overnight drain for easy maintenance

Applications:
Ideal for use in paint booths, automotive refinishing, and any application requiring clean, dry compressed air. Particularly suited for waterborne paint systems and protecting moisture-sensitive tools.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Install as close to the point of use as possible for best results
• Ensure proper air line sizing (minimum 5/16” hose, 3/8” optimum)
• Use flexible hose between compressor and main air line
• Install drain legs and ball valves for easy maintenance
• Drain system daily or as recommended
• Turn off air pressure for overnight drain operation
• Regularly check and drain filters and coalescers
• Follow manufacturer’s maintenance schedule
• Use only compatible fittings and hoses
