Introducing the Giacomini R89 Auto Air Vent: Efficiency and Reliability Redefined.
Giacomini is excited to introduce the new R89 Auto Air Vent, a high-performance solution engineered to eliminate trapped air from hydronic heating and cooling systems. Designed for seamless integration and long-term reliability, the R89 (available in part numbers R89Y001 and R89Y002) optimizes system efficiency, reduces maintenance, and enhances comfort. Whether you’re an installer, homeowner, or system designer, the R89 is the perfect addition to your hydronic setup. Read on to explore its features, applications, and specifications, and access the official documentation for complete details.
Why Choose the R89 Auto Air Vent?
Air pockets in hydronic systems can cause inefficiencies, corrosion, noise, and reduced performance, leading to higher energy costs and component wear. The R89 Auto Air Vent (part numbers R89Y001 and R89Y002) tackles these issues with precision and durability.
By automatically venting air, the R89 ensures optimal pressure, flow, and energy efficiency, protecting your system and enhancing its lifespan for Commercial systems & specialised applications.
The R89 is designed for performance, ease of installation, and versatility. Available in two sizes, it caters to a variety of system requirements:
Additional features include:
-
Automatic Air Venting: A high-precision float valve expels air without manual intervention, preventing air locks.
-
Corrosion-Resistant Materials: Constructed with brass body and high-grade polymer components for durability in harsh conditions.
-
High-Temperature and Pressure Tolerance: Suitable for systems with water temperatures up to 120°C and pressures up to 10 bar.
-
Leak-Proof Design: Integrated shut-off valve ensures secure operation and simplifies maintenance.
-
Compact and Lightweight: Both sizes are easy to install in confined spaces, ideal for retrofits and new installations.

The R89 Auto Air Vent (R89Y001 and R89Y002) is versatile and suited for a wide range of hydronic systems:
-
Radiator Systems: Install at the highest point of radiators to remove air and ensure even heat distribution.
-
Boiler Circuits: Prevent air-related inefficiencies and protect boiler components from corrosion.
-
Underfloor Heating: Maintain consistent flow in manifolds and loops for optimal thermal comfort.
-
Chilled Water Systems: Enhance cooling efficiency in commercial HVAC setups by eliminating air pockets.
-
Solar Thermal Systems: Protect high-temperature collectors and piping from air-induced damage.
The R89 is typically installed vertically at the highest points of a system or where air accumulates, such as risers, manifolds, or air separators. For enhanced maintenance convenience, pair it with a Giacomini check valve (e.g., R88Y001 for 1/2” or R88Y002 for 3/8”, sold separately) to allow removal without draining the
The R89 Auto Air Vent delivers significant advantages:
-
For Installers: The 1/2” (R89Y001) and 3/8” (R89Y002) threaded connections simplify installation, while the shut-off valve reduces maintenance time. The compact size fits tight spaces, minimizing labor and callbacks.
-
For Homeowners: Enjoy quieter operation, improved system efficiency, and lower energy bills due to optimized performance.
-
For System Designers: The R89’s durability, high-pressure tolerance, and compatibility with various systems make it a reliable choice for complex designs.
Installation and Maintenance Guidelines
Installing the R89 Auto Air Vent (R89Y001 or R89Y002) is quick and straightforward. Follow these steps for optimal performance:
-
Positioning: Install vertically at the system’s highest point or air collection area, ensuring the vent cap is accessible.
-
Connection: Use the 1/2” (R89Y001) or 3/8” (R89Y002) male thread, applying sealing material (e.g., PTFE tape) to ensure a tight fit.
-
Optional Check Valve: Install a matching check valve (R88Y001 for 1/2” or R88Y002 for 3/8**) below the R89 for easy removal without draining.
-
Testing: After installation, verify air release during system filling and check for leaks.
For detailed guidance, refer to the R89 Installation Instructions. Maintenance is minimal but includes:
-
Periodic Checks: Inspect the vent cap and valve for debris every 6–12 months.
-
Cleaning: If air release is reduced, clean the valve mechanism as outlined in the instructions.
-
Replacement: Replace the R89 if signs of wear or leakage appear to maintain system integrity.
