Elevate Your Hydronic Systems with the R88E Compact Automatic Air Vent

The new R88E from giacomini is a compact high-performance automatic air vent  engineered to eliminate trapped air from hydronic heating and cooling systems, preventing airlocks, corrosion, and reduced efficiency. 

As detailed in the Giacomini R88E datasheet, its standout features include:

Whether you’re upgrading an existing system or designing a new one, the R88E (R88EY002 for 3/8" or R88EY003 for 1/2") delivers reliable air venting for peak performance.

Available Here 

Compact Design: A space-saving footprint ideal for tight spaces, such as underfloor heating manifolds or radiator systems.

Integrated Filter: Captures debris and sediment to prevent clogging, ensuring reliable operation with minimal maintenance.

Horizontal Vent Discharge: Releases air efficiently in confined areas where vertical clearance is limited.

Automatic Operation: A float mechanism detects and expels air as it accumulates, eliminating the need for manual venting.

Durable Construction: Made from corrosion-resistant brass for long-term reliability in demanding conditions.

Available with male threaded connections in two sizes:

3/8" (Part Number: R88EY002): Perfect for smaller systems or compact installations.

1/2" (Part Number: R88EY003): Ideal for larger systems requiring higher flow capacity.

The R88E operates at a maximum pressure of 10 bar and a maximum temperature of 110°C, making it suitable for a wide range of hydronic applications, from residential heating to commercial cooling systems.

Why Choose the Giacomini R88E?

1.⁠ ⁠Enhances System Efficiency

Trapped air in hydronic systems can reduce heat transfer, cause airlocks, and increase energy consumption. The R88E’s automatic air release ensures consistent fluid flow, optimising system performance and lowering utility bills. By maintaining efficient operation, it delivers comfort and cost savings for homeowners and businesses.

2.⁠ ⁠Low Maintenance with Integrated Filter

The R88E’s integrated filter captures debris and sediment, preventing blockages in the venting mechanism. This reduces maintenance needs, making it an ideal choice for busy installers and end-users. The filter ensures the vent remains operational, even in systems with high particulate content, saving time and service costs.

3.⁠ ⁠Compact and Flexible Installation

With its compact design and horizontal vent discharge, the R88E (R88EY002 or R88EY003) is perfect for installations where space is at a premium. Its 3/8" or 1/2" male threaded connections simplify integration into existing systems, and the horizontal vent allows for flexible placement in tight spaces like boiler rooms or manifolds. This versatility speeds up installation and reduces labor costs.

4.⁠ ⁠Built for Long-Term Durability

Manufactured by Giacomini, a global leader in hydronic solutions with over 70 years of expertise, the R88E features a robust brass body that resists corrosion and withstands high pressures and temperatures. This durability ensures reliable performance in both potable water and heating applications, offering peace of mind for years to come.

5.⁠ ⁠Protects Your System

By removing air and preventing oxygen-related corrosion, the R88E safeguards critical components like boilers, pumps, and radiators. This extends the lifespan of your hydronic system, reduces repair costs, and enhances overall reliability, making it a smart investment for any project.

Applications of the Giacomini R88E

The R88E’s versatility makes it an essential component for a variety of hydronic systems, including:

Radiant Floor Heating: Eliminates air pockets for even heat distribution, ensuring consistent warmth and comfort.

Radiator Heating Systems: Prevents airlocks and noisy operation, improving system reliability and user satisfaction.

Boiler Systems: Protects boilers from corrosion, extending equipment life.

Cooling Systems: Maintains efficient fluid flow in chilled water systems for optimal cooling performance.

Potable Water Systems: Suitable for sanitary applications, ensuring compliance with safety standards.
