The Helios FK‑T 150÷150÷200 is a flat duct T‑piece constructed from galvanized steel sheet, featuring a flat design and rigid construction. It is part of an underfloor duct system that is corrosion-resistant and non-combustible. Connections are made using external connecting sleeves, resulting in completely smooth inner walls that minimize flow resistance and reduce dirt deposits. This product is designed for volume flows up to 90 m³/h and is ideal for concealed air duct systems in domestic ventilation applications.
