JETLINE-150 ECOWATT is an in-line EC duct fan for general ventilation of dwellings and light commercial spaces. The 150 model uses a 230 V EC motor (IP44) with 0–10 V speed control via an onboard potentiometer or external signal, and features manual‑reset thermal protection. Its galvanized steel housing includes a mounting bracket and inlet/outlet gaskets; the impeller, guide vanes and outlet diffuser are injection‑moulded plastic to improve flow and reduce noise. For 150 mm nominal ducts, the spigot diameter is 145 mm. At maximum control signal it delivers up to 680 m³/h, and the 323 × 298.5 × 348 mm body fits tight service runs. Supply or extract ventilation.
