Ventur’s Jetline-100 Ecowatt is a compact mixed‑flow in‑line fan for circular ducts. The housing is galvanized steel, while the impeller, guide vanes and outlet diffuser are injection‑moulded plastic. It uses an EC motor (230 V, 50/60 Hz, IP44) with speed set either by an on‑board potentiometer or an external 0–10 V signal. A mounting bracket is supplied, rubber gaskets on the spigots improve airtightness, and a silent‑block between motor and bracket reduces vibration. The 100 model connects to nominal 100 mm ducting; the spigot diameter in the dimensions table is 95 mm. Maximum free‑airflow is 260 m³/h. Typical uses include extract or supply.
