The GRACO Air Control SDU (Part No. 25E029) is a genuine air control module designed for use with GRACO sanitary drum unloader (SDU) systems. This component ensures precise regulation of compressed air supply, critical for maintaining efficient and hygienic fluid transfer in food, beverage, pharmaceutical, and industrial applications.

Key Features

• Genuine GRACO air control for SDU systems (Part No. 25E029).
• Integrated air filter/regulator removes contaminants and moisture from compressed air, extending pump lifespan.
• Adjustable air pressure control optimizes pump speed and outlet pressure for consistent material evacuation.
• FDA-compliant construction with corrosion-resistant materials suitable for sanitary environments.
• Bleed-type master air valve safely relieves trapped air pressure during maintenance or shutdown.
• OEM quality ensures compatibility with GRACO SDU systems like the Model 234015 and Husky 2150 FDA pumps.

Technical Specifications

• Maximum air pressure: 125 psi (8.6 bar).
• Air inlet/outlet: 3/4" NPT.
• Filter element: 40-micron polypropylene screen.
• Materials: Stainless steel, PTFE, and FDA-compliant elastomers.

Application/Installation Notes

1. Installation:
• Mount the air control module upstream from the pump, ensuring proper alignment with the air supply line.
• Use GRACO-approved conductive hoses and fittings to prevent static buildup.
• Blow out air lines before installation to remove debris.
2. Operation:
• Adjust the regulator knob to set air pressure based on pump requirements (refer to GRACO’s SDU manual for pressure guidelines).
• Regularly drain the filter bowl to maintain airflow efficiency.
3. Maintenance:
• Replace filter elements periodically or when contamination is visible.
• Inspect seals and valves for wear during routine servicing.

Compatibility

• Designed for GRACO SDU systems requiring precise air control in hygienic applications (e.g., drum unloading for viscous foods, creams, or chemicals).
