K250L Centrifugal Duct Fan AC Motor 250mm 10"

The Systemair K250L is a centrifugal inline duct fan designed for installation in circular ducting, with minimum 25 mm spigot connections. It has backward-curved blades and an external-rotor motor, and its folded galvanised sheet-steel casing is close to airtight — making outdoor and duct-connected wet-room applications possible (corrosion class C3). It delivers up to 950 m³/h through 250 mm duct. Airflow up to 950 m³/h; 250 mm connection (25 mm spigots) Speed-controllable AC, 230 V, 1~, 50 Hz (stepless thyristor or 5-step transformer) Backward-curved external-rotor motor; impedance/thermal protected Near-airtight folded galvanised-steel casing; corrosion class C3; outdoor/wet-room capable Low noise; can be installed in any position; fixing bracket and screws included Maintenance-free and reliable Suitable for Duct-mounted extract and supply, including outdoor and wet-room applications Commercial and domestic circular duct systems Installation Installs in any position using the included fixing bracket. Speed control via thyristor or 5-step transformer. Should be installed on a suitable circuit by a qualified electrician.
