The Helios MiniVent M1/150 is a powerful yet ultra-quiet extractor fan featuring a highly efficient EC motor with two speed settings — 260 and 220 m³/h. Designed to blend seamlessly into modern interiors, its compact, elegant front panel conceals the fan’s internal components for a clean and discreet appearance. The unit is equipped with an airtight back draught shutter to prevent unwanted airflow when not in use. Thanks to Helios’ ultraSilence technology, the noise level remains low at just 35 dB(A) when running at 220 m³/h. Ideal for use in bathrooms, toilets, and other small rooms, the M1/150 offers energy-efficient and effective ventilation for improved indoor air quality
