Jetline-125 is Ventur’s compact in-line duct fan for general ventilation. The low-profile housing is formed from galvanized steel with a factory bracket and gaskets at the inlet and outlet. An injection-molded impeller, guide vanes and a diffuser help stabilize pressure while keeping noise controlled. The unit uses a single-phase 230 V motor with IP44 protection and manual-reset thermal cut-out, and is suitable for continuous service in clean air from −20 to +60 °C. Designed for 120 mm round ducts, the 125-size delivers up to 420 m³/h, making it a practical choice for small extraction or supply runs in apartments, offices and light commercial rooms. Speed control can be added via external regulators.
