System 204 High Efficiency Green Line Horizontal 90 Degree Elbow Bend

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.

• Smoothly channels air through the duct bend in a uniform flow
• Performance has been tested by the Building Research Establishment (BRE)
• Significantly reduces duct bend resistance for improved airflow and overall energy usage
• Reduces airspeed through the bend to lower system noise
• The colour of the internal vanes as shown in the image is illustrative (manufactured in white).
