K Fan 125 M AC is Global Air Supplies’ 125 mm variant of the Systemair K series circular inline extractor. It delivers a maximum free‑air flow of 187 m³/h through a 125 mm (12.5 cm) spigot, suitable for small tents and compact duct runs. The sealed, galvanised steel housing prevents leakage from filtered systems, and the backward‑curved motorised impeller is engineered for efficient, continuous operation. The unit is IP55 rated, maintenance‑free, thermally protected, and speed‑controllable via triac or voltage regulators. Made in Germany and supplied with a 2‑year warranty. When paired with an appropriate carbon filter, typical flow is around 146 m³/h, depending on system pressure and ducting layout.
