SYSTEM 204 HIGH-EFFICIENCY GREEN LINE HORIZONTAL 90 DEGREE ELBOW BEND
Due to the profile of a duct bend, air travelling through it can become turbulent, causing increased resistance and system noise. As a consequence, the mechanical extract appliance will need to work harder in order to meet the required airflow rates; therefore consuming more energy.
Domus Green Line high efficiency 90° duct bends have been specifically designed to enable a uniform flow of air through the section of duct, reducing the duct bend resistance by up to 60% and lowering the airspeed. All of which results in a quieter and more efficient ventilation system.
