Key Features of Dublin 1690 000 105 Rotary Union

1. Ultra-Low Friction Sealing Technology​

At the core of this air rotary union is its proprietary sealing system, featuring self-lubricating PTFE (polytetrafluoroethylene) seals paired with carbon-graphite faces. This combination delivers exceptional resistance to wear and friction, even at high rotational speeds (up to 8,000 RPM), while maintaining a tight seal to prevent air leakage. The seal design is optimized for clean air systems, reducing particulate accumulation and ensuring consistent performance in dusty or harsh environments.​
Benefits: Minimizes pressure drop, reduces energy loss, and eliminates air leaks, critical for maintaining pneumatic system efficiency.​

2. High-Purity Materials for Contamination-Free Air Transfer​

The union’s body is constructed from aerospace-grade aluminum alloy (6061-T6) for lightweight durability, while internal components are precision-machined from stainless steel (304 or 316L) to resist corrosion and particulate buildup. This material combination is ideal for applications requiring clean air, such as food and beverage processing or pharmaceutical manufacturing, where contamination could compromise product quality or safety.​
Benefits: Ensures air purity, complies with FDA and ISO 14644-1 standards for cleanrooms, and withstands corrosive environments.​

3. Dynamic Balance for High-Speed Stability​

Using computational fluid dynamics (CFD) and finite element analysis (FEA), the Dublin 1690-000-105 Air Rotary Union is engineered for balanced rotation at speeds up to 8,000 RPM. Its precision-machined rotor and stator minimize axial and radial runout, reducing vibration and noise, critical for maintaining stability in high-speed automation systems like robotic welding arms or CNC machining centers.​
Benefits: Quiet operation, extended equipment lifespan, and improved process precision in high-speed applications.​

4. Wide Pressure and Temperature Range​

Designed to handle the full spectrum of pneumatic system requirements, this air rotary union supports pressure ranges from vacuum (-1 bar) up to 20 bar (290 PSI) and temperatures from -20°C to 150°C (-4°F to 302°F). This versatility makes it suitable for both low-pressure control systems (e.g., air bearings) and high-pressure applications (e.g., pneumatic actuators).​

5. Customizable Configurations for Diverse Applications​

Understanding the unique needs of industrial pneumatic systems, the Dublin 1690-000-105 Air Rotary Union offers extensive customization:​
Connection Types: Push-to-connect fittings (ISO 8573-1), threaded ports (NPT, BSP, metric), or flanged interfaces for easy integration with existing tubing/cabling.​
Port Sizes: 4mm to 25mm (1/8″ to 1″) to accommodate varying air flow rates (up to 5,000 Nm³/h).​
Seal Upgrades: Silicon carbide or tungsten carbide seals for abrasive environments (e.g., systems with entrained particulates).​
Multi-Line Designs: Optional dual-channel or quad-channel configurations for simultaneous air and vacuum transfer.​
Our engineering team provides tailored solutions to match your system’s exact specifications, ensuring optimal performance and compatibility.

Advantage of Dublin 1690 000 105 Rotary Union

1. Energy Efficiency Through Leak Prevention​

The union’s precision seals reduce air leakage by up to 99%, a critical advantage in compressed air systems where even minor leaks can waste up to 30% of generated air. In a typical factory, this translates to lower energy bills and reduced compressor wear, delivering a rapid return on investment (ROI).​

2. Minimal Maintenance & Long Service Life​

Thanks to its self-lubricating seals and corrosion-resistant materials, the Dublin 1690-000-105 Air Rotary Union requires maintenance only once every 10,000 operating hours—50% less than standard unions. Quick-release seal cartridges enable easy replacement without disassembling the entire system, minimizing downtime during servicing.​

3. Consistent Pressure Control​

Stable air pressure is essential for pneumatic actuators, valves, and tools. This union’s low-pressure-drop design (≤0.5 bar at maximum flow) ensures uniform pressure distribution, improving the accuracy of motion control systems and reducing cycle time variations in automated processes.​

4. Compliance with Industry Standards​

The union meets international standards for pneumatic components, including ISO 6431 (hydraulic/ pneumatic systems) and OSHA (safety requirements for compressed air). Its food-grade material options (316L stainless steel, FDA-compliant seals) make it suitable for hygienic applications in the food, beverage, and pharmaceutical industries.
