Wall fan airRoxy Planet Energy FI 125 HS with humidity sensor — model 01-098, Ø125 mm

Wall-mounted airRoxy Planet Energy FI 125 HS is a compact extractor fan with a 125 mm diameter and an integrated humidity sensor designed for intermittent and automatic extract ventilation. It is intended for installation on walls in bathrooms, kitchens and utility rooms to remove moist, stale or odorous air. The unit combines a low-noise motor, simple electrical connection and a discreet front grille to suit domestic and light-commercial interiors.

Advantages

The built-in humidity sensor enables automatic activation when relative humidity rises above a set threshold, reducing manual control needs and helping prevent condensation. The fan offers timed overrun operation so airflow continues after the control signal stops, ensuring effective moisture removal. Compact dimensions and a wall-mount design simplify installation; quiet motor operation minimizes disturbance in living spaces. The model is compatible with standard ducting and provides energy-efficient ventilation for small to medium rooms.

Suitable for

• Bathroom extract ventilation to reduce humidity and prevent mold formation
• Kitchen ventilation for removing steam and cooking odours
• Utility rooms, laundry rooms and small WC installations
• Residential and light-commercial spaces requiring intermittent or humidity-controlled ventilation

Key specifications

• Impeller diameter: 125 mm
• Mounting type: wall-mounted installation
• Control: built-in humidity sensor and timer overrun function
• Typical application: extract ventilation for bathrooms, kitchens and utility rooms
• Noise characteristics: designed for low-noise operation suitable for living spaces
• Electrical connection: mains-powered with simple wiring for switched or permanent supply
• Airflow direction: exhaust (extract) ventilation

How to use

Install the fan in an external wall or ducted position according to the mounting instructions and local electrical regulations. Connect the fan to the mains supply and select the preferred wiring mode: humidity-controlled automatic mode or switched operation with timer overrun. Adjust the humidity threshold and timer settings if the model provides user-accessible controls, then verify correct airflow direction and secure the front grille. Routine checks and occasional cleaning of the grille and impeller will help maintain performance.

Usage recommendations

To ensure effective humidity control, position the fan where it can detect moist air rising from the main source (for example, near the shower or sink). Avoid installing the unit directly above heat sources or where airflow is obstructed. Periodically inspect and clean the grille and impeller to prevent dust buildup and maintain quiet operation. For permanent or high-demand ventilation needs, consider a larger-capacity or continuous-duty solution.
