K Fan 200 mm EC by Global Air Supplies is a German-built inline centrifugal duct fan using an electronically commutated (EC) motor. It connects to G.A.S. digital EC controllers via 0–10 V signal, enabling smooth, hum-free speed control. The galvanized steel housing integrates motor control and thermal protection and is maintenance‑free. At 200 mm (8 in) duct size, the fan delivers a free‑air maximum of 774 m³/h, suitable for medium tents or small rooms when paired with an appropriate carbon filter. The unit is designed for hard‑wired mains via an IP55 terminal box and carries a two‑year warranty. Part of the Systemair K series, it offers efficient airflow with reduced running costs compared to equivalent AC fans.
