Rectangular Angled Tee with Circular Branch

The AD-TK rectangular angled tee with a round branch is designed to connect a round duct to a rectangular ventilation channel at an angle. The angled configuration ensures smoother airflow distribution, reducing turbulence, pressure losses, and noise levels within the ventilation system.

The tee is coaxial, equipped with flanges at both ends, and reinforced with transverse corrugation of the steel sheet to provide increased rigidity and structural stability. The round branch is supplied as standard with a nipple connection and is mounted on the side wall of the tee. The branch angle depends on the inclination of the side wall and is selected according to specific project requirements.

This fitting is widely used in ventilation and air-conditioning systems where compact installation and efficient airflow transition from rectangular to round ducts are required.

Technical parameters:

• Minimum duct length: Lmin = 2E

• Minimum E value: Emin = D/2 + 100 mm

• Minimum round branch diameter: Dmin = 100 mm

• Diameter D must be smaller than dimensions B and C
