Duct fittings and combinations, such as ells, tees, and reducers, are responsible for balancing airflow and equalising duct pressure. It's an air distribution box for an HVAC system's central distribution and collecting air flow unit.
Takeoffs, turning vanes, cleats, and other specialised connections can join duct trunks and pipes, which can also be terminated with angled boots. These parts work together to generate passageways that carry fresh air into your home.
