Ventur JETLINE-150 is a compact in-line centrifugal duct fan for general ventilation in circular ducts. The low-profile galvanized steel housing integrates a mounting bracket and junction box; the impeller, guide vanes and outlet diffuser are molded plastic, with inlet/outlet gaskets and a silent‑block isolating the motor from the bracket. It uses a single‑phase 220–240 V, 50/60 Hz motor with IP44 protection and manual‑reset thermal cut‑out. The JETLINE‑150 fits a 145 mm spigot and is intended for exhaust or supply ventilation. Maximum airflow is 750 m³/h (50 Hz), with models covering 100–315 mm across the range. Accessories include backdraft dampers, silencers and speed controllers supported by the series.
