Air Duct Reducer

The Air Duct Reducer makes it easy to connect ducts of different sizes, creating a smooth, efficient airflow path for your ventilation system. It’s a simple piece of hardware that plays an important role in keeping air moving freely throughout your space.

Available in two size combinations—6″ (150 mm) to 4″ (100 mm) and 8″ (200 mm) to 6″ (150 mm)—it helps you adapt your HVAC setup without leaks or airflow loss. Made from high‑quality, moisture‑resistant PP plastic, it stays strong and corrosion‑free, even in damp environments like bathrooms or kitchens.

Installation is straightforward: just secure it using standard duct tape or clamps. Once connected, you’ll have a tight, reliable seal ready to handle everyday air circulation for homes, offices, apartments, or commercial HVAC systems.

It’s a small part that quietly keeps the whole ventilation system running smoothly—simple, sturdy, and built to last.
