This online resource is a catalog for turbo deflectors, a type of ventilation device designed to increase suction in natural ventilation systems. The deflectors are shaped like a rotating sphere, consisting of a stationary base and a rotating dome, driven by the wind. The deflector rotates in one direction only, regardless of wind direction, and is more efficient than regular deflectors due to the creation of necessary pressure differences for smooth airflow. The base is made of high-quality steel for secure attachment to various roof types. The rotor shaft comes with factory balancing for uniform and smooth rotation. The catalog offers various sizes and materials for the deflectors, including oiled-coated steel and PVC coatings, and a range of available colors in RAL tones.
