## Long description

The AWENTA Silent 100H SYSTEM+ inline fan housing with hygrostat and timer is a ducted ventilation unit designed for humidity-controlled extraction in bathrooms, kitchens and small utility spaces. The housing integrates a hygrostat that activates the fan when relative humidity rises above a preset threshold, and a timer function that allows adjustable delayed stop after the humidity drops. The unit is intended for installation into existing ductwork to provide automated ventilation based on moisture levels and timed operation.
Advantages
This inline fan housing provides automatic humidity-based control through the built-in hygrostat, reducing the need for manual switching. The adjustable timer enables delayed stop to clear residual moisture and odors, improving indoor air quality while limiting unnecessary runtime. The Silent 100H SYSTEM+ design facilitates quiet operation suitable for domestic environments and compact spaces. Integration into duct systems allows flexible placement of the fan housing away from the room, which helps lower perceived noise at the grille.
Suitable for
 Bathroom extraction to control humidity after showers
 Kitchen ventilation where intermittent moisture and odors occur
 Small utility rooms, laundries and cloakrooms requiring moisture management
 Ducted ventilation systems needing automated humidity-triggered operation
Key specifications
 Inline housing format for ducted installation
 Integrated hygrostat for automatic activation based on relative humidity
 Adjustable timer function for delayed stop after humidity decreases
 Designed for quiet operation suitable for residential spaces
 Compatibility with standard circular duct connections (check installation dimensions before fitting)
How to use
Install the Silent 100H SYSTEM+ housing into the duct run in accordance with local ventilation and electrical regulations. Set the hygrostat threshold to the desired relative humidity level at which the fan should start, and adjust the delayed stop timer to the required runtime after humidity falls below the threshold. When humidity in the served space rises above the set level, the hygrostat will switch the fan on automatically; the timer will keep the fan running for the selected delay once humidity returns to normal. Regularly inspect the duct connections and ensure the power supply and mounting are secure.
Usage recommendations
For reliable performance, mount the housing where airflow is unobstructed and away from direct splash zones. Periodically check and clean connected ducts and grilles to maintain airflow. Configure the hygrostat and timer according to room size and typical moisture generation to balance air exchange with energy use.
