Wall/ceiling domestic fan airRoxy dRim FI 100 HS BB with humidity sensor and ball bearing

airRoxy dRim FI 100 HS BB is a compact wall or ceiling domestic ventilation fan designed for extract ventilation in bathrooms, kitchens and utility rooms. The unit integrates a humidity sensor that automatically activates extraction based on increased moisture levels and uses ball bearings for reliable, long-lasting motor operation. Compatible with standard 100 mm duct connections, this fan supports both intermittent and continuous ventilation modes and is intended for residential use where moisture control and quiet, dependable extraction are required.

Advantages

The fan combines an automatic humidity sensor with a ball-bearing motor to provide responsive operation and enhanced durability. Its compact design allows installation on walls or ceilings and fits standard round ducts with a 100 mm diameter. The humidity control reduces manual intervention, while the ball bearings improve running life and stability during continuous use. The fan's focus on simple installation and moisture-triggered operation makes it suitable for maintaining indoor air quality in confined wet areas.

Suitable for

• Bathrooms and shower rooms requiring moisture-sensitive extraction
• Kitchens and cooking areas for intermittent ventilation of steam and odors
• Utility rooms, laundry areas and small basements with elevated humidity
• Wall- or ceiling-mounted installations with a 100 mm duct connection

Key specifications

• Installation type: wall or ceiling mounting
• Duct compatibility: 100 mm round duct connection
• Control: integrated humidity sensor for automatic activation
• Motor bearing type: ball bearing for extended service life
• Intended operation: intermittent or continuous extract ventilation

How to use

Mount the fan on a suitable wall or ceiling surface using appropriate fasteners and ensure secure connection to a 100 mm ventilation duct. Connect the unit to the electrical supply following local wiring regulations and the manufacturer's installation instructions. The integrated humidity sensor will detect elevated moisture and automatically start the fan; set-up and sensitivity adjustments, if available, should be performed per the product manual. For continuous ventilation, configure the power supply or control circuitry accordingly.

Usage recommendations

Place the fan where it can efficiently remove moist air at the source, for example near showers or laundry equipment, and ensure the duct route allows unobstructed airflow. Regularly inspect and clean the fan's grille and impeller to maintain performance; verify electrical connections and mounting stability during periodic maintenance.
