The 220 x 90mm flat PVC T-joint creates a 90-degree branch from a rectangular duct run, allowing one air path to serve two outlets or combine two branches into a common line. Its purpose-made geometry provides a cleaner and more secure connection than cutting a branch into the duct on site. Manufactured from lightweight, corrosion-resistant PVC, the fitting is easy to install and integrates with the matching Airmiq flat duct system. It is suited to multi-room residential extraction and other low-pressure supply or exhaust applications.
