Inline duct fan VENTS QUIET100TH-Style d100 with timer and humidity sensor

VENTS QUIET100TH-Style d100 is a compact inline duct fan designed for ventilating small rooms with a 100 mm duct connection. Engineered for low-noise operation, this model integrates a timer and an adjustable humidity sensor to enable automatic extraction based on relative humidity levels. The fan is suitable for concealed installation in ventilation ducts and provides a controlled air exchange for bathrooms, toilets, kitchens and utility rooms where space is limited and moisture control is important.

Advantages

The QUIET100TH-Style combines compact dimensions with quiet operation and automated control. Its built-in humidity sensor allows the fan to start and stop according to preset humidity thresholds, reducing manual intervention and helping prevent moisture buildup. The integrated timer extends operation after humidity drops, ensuring thorough air extraction. Designed for inline installation, the fan can be positioned away from the room to minimize noise while maintaining effective airflow.

Suitable for

• Bathroom and shower rooms where humidity control is required
• Toilets and small WC spaces
• Kitchens and pantry areas with limited ventilation
• Utility rooms, laundry rooms and wet rooms

Key specifications

• Airflow direction: inline duct configuration for exhaust or supply integration
• Duct connection diameter: 100 mm
• Integrated controls: adjustable humidity sensor and delay timer
• Noise characteristics: engineered for quiet operation suitable for domestic spaces
• Mounting: inline/duct installation, suitable for concealed placement within ductwork

How to use

Install the fan into the ventilation duct with a 100 mm connection, ensuring correct orientation for airflow. Connect the electrical supply following local regulations and the fan wiring diagram. Set the humidity threshold to the desired relative humidity level at which the fan should start, and adjust the timer for the required post-run duration to continue extraction after humidity decreases. Positioning the unit within the ductwork away from the room minimizes perceived noise while maintaining performance.

Usage recommendations

For reliable operation, ensure ductwork is clean and unobstructed and that the fan is installed with appropriate vibration isolation. Use the humidity sensor setting suitable for the room type (higher sensitivity for frequently wet areas). Periodically check electrical connections and clean the fan housing if access is provided.
