Rectangular Elbow with Variable Cross-Section

The AD-KRP rectangular elbow with variable cross-section is designed to change the airflow direction by 90° in rectangular ventilation ducts while simultaneously adjusting the duct cross-sectional dimensions. This design allows flexible routing of duct systems without compromising airflow efficiency.

The elbow is equipped with flanges at both ends and reinforced with transverse corrugation of the steel sheet, providing increased rigidity and reliable performance under high airflow velocity and pressure conditions.

This fitting is recommended for ventilation and air-conditioning systems with intensive airflow where a 90° turn combined with a change in duct cross-section is required.
