Graco 234418 3-Stage Membrane Drying System

Compatible Machines & Applications

The Graco 234418 3-Stage Membrane Drying System is an inline compressed-air preparation system. It is not a spray machine itself but is designed to work with a wide range of air-powered and finishing equipment that require clean, dry air.

• Air-operated paint spray systems
• HVLP and conventional air spray guns
• Air-assisted airless spray systems
• Industrial pneumatic tools
• Compressed air supply lines for finishing booths
• Fluid dispensing and coating systems
• Workshop and production air compressor setups

Product Overview

The Graco 234418 system delivers high-quality, moisture-free air through a three-stage filtration and drying process. It protects downstream equipment, improves finish quality, and reduces maintenance caused by moisture and oil contamination in compressed air lines.

How the 3-Stage System Works

• Stage 1: Removes bulk water, dirt, and larger particles from compressed air.
• Stage 2: Eliminates oil aerosols and fine contaminants to protect sensitive equipment.
• Stage 3: Uses membrane technology to remove remaining moisture without desiccant.

This design ensures consistent air quality while reducing downtime and ongoing maintenance costs.

Key Benefits

• Improves paint finish quality and consistency
• Prevents moisture-related equipment damage
• Reduces oil and particle contamination
• No desiccant replacement required
• Suitable for continuous industrial use
