Air bubble separator Spirovent RV2 1" with rotating flange UA100W

Air Microbubble Separators – Key to an Efficient Installation

The Spirovent RV2 air microbubble separator is a device designed to remove gases and air microbubbles from heating and cooling systems. Its operation enhances system efficiency, reduces operating costs, and increases reliability. Installing this separator—especially in combination with a dirt separator—can yield energy savings of several percent.

Design and Operating Principle

Spirovent RV2 utilizes a specialized design with an integrated automatic air vent (Spirotop), enabling effective removal of both free air and microbubbles. Thanks to its rotating connection flange, installation is highly flexible—possible on pipelines oriented in any direction: horizontal, vertical, or inclined. At the heart of the device lies the Spirotube element, which efficiently separates air from the heating or cooling fluid. The robust brass housing ensures long-term, trouble-free operation.

Applications and Benefits

This separator is suitable for heating and cooling systems, as well as systems using water-glycol mixtures (up to 50% glycol content). Installing it on the supply or return line ensures continuous air removal, delivering multiple benefits:

• Improved heating efficiency: Air removal enables uniform heat distribution throughout the system, eliminating cold spots in radiators.
• Reduced operating costs: A more efficient system requires less energy to heat spaces.
• Extended system lifespan: Air elimination reduces corrosion and pump cavitation, prolonging the life of system components.
• Quiet operation: Removing air minimizes noise and rattling in pipes and pumps.
• Minimal maintenance: Once installed, the separator requires no additional servicing—it operates continuously and autonomously.
• Universal installation: The rotating flange simplifies retrofitting into existing systems without complex modifications.

Operating Parameters and Compliance

The Spirovent RV2 separator is rated for maximum operating pressure of 10 bar and temperatures up to 110°C. Its robust construction and high-quality materials ensure reliable long-term performance. The device is compatible with various pipe types thanks to multiple available internal thread sizes (in this case, 1 inch). Consider using the additional TUR100 insulation to further enhance the system’s energy efficiency.
