MiniVent M1/120 small fan features two power stages (170/150 m³/h), codable 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 the high or low power level. With its excellent design, the MiniVent M1 blends harmoniously into any environment, including sophisticated rooms. The closed, stylish facade completely conceals the fan opening. It comes standard with a tightly closing return air damper. Thanks to the new ultraSilence technology, the noise level is only 32 dB(A) at a volume flow of 150 m³/h. This fan is universally applicable for the ventilation of bathrooms, WCs, and other small rooms.
