The MiniVent M1 small fan offers two power levels (90/75 m³/h) with coded after-run and interval operation. The start delay can be set to approximately 0, 45, 90, or 120 seconds, while the after-run time can be adjusted to about 6, 10, 15, or 21 minutes. The settings for the interval operation include approximately 0, 8, 12, or 24 hours. The electronic functions can be configured for either high or low power levels. With its excellent design, the MiniVent M1 blends harmoniously into any environment, even in demanding spaces. The closed, elegant facade completely conceals the fan opening. It comes standard with a tightly sealing backdraft shutter. Thanks to the new ultraSilence technology, the noise level is only 25 dB(A) at an airflow rate of 75 m³/h. It is universally applicable for ventilating bathrooms, WCs, and other small rooms.
