Ventur’s JETLINE-200 is a compact in-line duct fan for general ventilation of apartments, offices, shops and restaurants. The galvanised steel housing integrates a mounting bracket and junction box; the impeller, guide vanes and outlet diffuser are injection-moulded plastic, with gaskets on inlet and outlet to reduce leakage. A single-phase 220–240 V motor (IP44, class F) with manual‑reset thermal protection powers the unit. The JETLINE‑200 connects to 200 mm class ducting; the spigot diameter is 195 mm per the manufacturer’s dimension table. At 50 Hz it delivers up to about 1080 m³/h, suitable for medium duct runs in supply or extract applications. Operating temperature range for the series is typically −20 to +60 °C. Speed control can be via electronic or transformer regulators.
