Helios Ventilatoren 6172 M1/100 N/C Minivent DN100 two-stage with run-down content_copy

The MiniVent M1/100 N/C fan from Helios Ventilatoren is a compact, two-stage fan for ventilating small rooms such as bathrooms, WCs or kitchens. With the type designation M1/100 N/C and manufacturer number 6172, it is designed for use in residential and commercial rooms where discreet, quiet and efficient ventilation is required. The device features two performance stages with an air flow rate of 90 m³/h (high stage) and 75 m³/h (low stage), where electronic functions such as delayed run and interval operation can be optionally set to either of the two stages. The ultraSilence technology ensures a low noise level of 25 dB(A) at the low performance stage (75 m³/h), enabling quiet operation even in sensitive environments.

Applications
The MiniVent M1/100 N/C is universally suitable for ventilating rooms with limited volume, particularly in bathrooms, toilets and small kitchens. The closed, aesthetically pleasing facade ensures that the fan opening is not visible, improving the visual appearance in the room. The integrated backdraft damper closes tightly to prevent unwanted air backflow, which is especially important for ventilating wet rooms.

Functions and equipment in detail
The device offers a codable delayed run and interval operation. The delayed run time can be set to approximately 6, 10, 15 or 21 minutes to ensure an additional ventilation phase after operation. The interval operation can be set to approximately 0, 8, 12 or 24 hours, enabling automated, time-controlled ventilation. The start delay can be set to approximately 0, 45, 90 or 120 seconds to ensure a gentle start of the fan. These functions can be optionally adjusted to the high or low performance stage, enabling flexible use according to room requirements.

Technology explained simply
The ultraSilence technology reduces operating noise through optimised fan geometry and electronic control. The noise level of 25 dB(A) at 75 m³/h corresponds to a quiet, almost inaudible operation that hardly disturbs in living rooms. The backdraft damper prevents air from flowing back from the fan into the room, promoting hygiene and energy efficiency. The codable operating functions allow individual adaptation to specific ventilation requirements without requiring additional control devices.

Compatibility and accessories
Various accessories are available for the MiniVent M1/100 N/C, facilitating installation and adaptation to different installation situations. These include the mounting flange MF 100 (article number 6188), the wall mounting kit WES 90/100 (diameter 110 mm) and the telescopic wall sleeve TWH 90/100 (article number 6352). These components enable flexible mounting on walls or ceilings, depending on existing installations and spatial conditions.

Installation and mounting
The fan is designed for built-in installation in walls or ceilings. Mounting is done via the integrated flange or with additional mounting accessories such as MF 100 or WES 90/100. Installation requires a corresponding opening in the building element and connection to the electrical network. The electronic functions are set via an integrated coding mechanism, described in the operating instructions or technical documentation provided by the manufacturer.

Operational advantages
The MiniVent M1/100 N/C offers a quiet, efficient and aesthetically pleasing ventilation solution. The integrated backdraft damper ensures hygienic conditions, while the codable operating functions enable flexible use. The low noise emission and discreet design make the device especially suitable for residential and commercial rooms where unobtrusive ventilation is required. The two-stage performance selection allows adaptation to different ventilation needs without requiring additional devices.
