MiniVent M1 small fan features two performance levels (90/75 m³/h) with coded run-on and interval operation. The start-up delay can be set to approximately 0, 45, 90, or 120 seconds, while the run-on time can be adjusted to about 6, 10, 15, or 21 minutes. Interval operation settings 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 sophisticated rooms. The closed, elegant façade completely conceals the fan opening. It comes standard with a tightly closing return air shut-off damper. Thanks to the new ultraSilence technology, the noise level is just 25 dB(A) at a volume flow of 75 m³/h. It is universally applicable for the ventilation of bathrooms, WCs, and other small rooms.
