XStream Vent-Clean Air, Dirt Separator (DN25) G1F Flamco XStream air and dirt separators ensure lower energy consumption, reduced wear, fewer failures, a longer lifespan, and thus higher efficiency in heating and cooling systems. Effective communication. From a system engineering perspective, it is always better to install a separate air and dirt separator. For installations where it is difficult to install both Flamco XStream Vent and Clean units, Flamco XStream Vent-Clean is the ideal solution. Unique ECO/MAX mode. In ECO mode, a portion of the system water (partial flow) is directed through the Flamco XStream separator. In MAX mode, the entire system water flows through the Flamco XStream separator. Up to 15% less energy consumption in the heating system. Up to 6% higher efficiency of the heating system. The device is designed for easy installation and can be rotated 360 degrees. There is no need to consider the flow direction during installation, which prevents installation errors. Thanks to the strong internal magnet, Flamco XStream Clean and Vent-Clean effectively attract magnetic particles. Insulation is a key component of the Flamco XStream design, minimizing heat loss. The integrated service indicator shows when the system was last cleaned in MAX mode.
