K Fan 100 mm XL AC by Global Air Supplies is a compact inline centrifugal duct fan for 100 mm (10 cm) ducting. The XL AC variant delivers higher pressure and flow than the M size, and is rated up to 285 m³/h maximum airflow. Its galvanised steel, sealed housing prevents leaks, helping keep odours and contaminants within filtered systems. A backward‑curved, motorised impeller is speed‑controllable with triac/voltage controllers, and integrated thermal protection safeguards the motor. The unit is IP55 rated, maintenance‑free, and manufactured in Germany, with a two‑year warranty. The fan is part of the Systemair K Series distributed by G.A.S and is available in multiple sizes to match common CarboAir filter pairings for balanced extraction.
