Bathroom extractor fan ORNO OR-WL-3200/100/HT 100 mm surface-mounted with humidity sensor and timer

ORNO OR-WL-3200/100/HT is a surface-mounted bathroom extractor fan with a 100 mm outlet, an integrated humidity sensor and an adjustable timer. Designed for installation on walls or ceilings in bathrooms, toilets and small utility rooms, the unit detects increased humidity levels and activates automatically to extract moist air and odors. The fan continues to run for a preset time after humidity falls, helping to reduce condensation and maintain better indoor air quality.

Advantages

The fan combines a compact surface-mounted design with an automatic humidity sensor and timer, enabling hands-free operation and energy-efficient ventilation. Its 100 mm outlet provides a balance between airflow and low noise suitable for small rooms. The adjustable timer allows setting the post-run time to match ventilation needs, while the humidity sensor ensures activation only when required.

Suitable for

• Bathrooms and showers where moisture control is needed
• Toilets and WC rooms requiring odor removal
• Small laundry rooms or utility spaces with occasional humidity
• Wall or ceiling installations in residential apartments and small commercial premises

Key specifications

• Mounting type: surface-mounted for wall or ceiling installation
• Outlet diameter: 100 mm
• Control: integrated humidity sensor with automatic activation
• Timer: adjustable post-run timer to continue operation after humidity drops
• Application: designed for bathroom, toilet and small utility room ventilation

How to use

Install the extractor fan on a suitable wall or ceiling surface, connecting it to the building electrical supply following local regulations and safety standards. Set the humidity threshold so the unit starts automatically when moisture rises. Adjust the timer to determine how long the fan runs after humidity returns to normal. Regularly inspect the fan and clean the exterior grille to prevent dust accumulation and ensure proper airflow.

Usage recommendations

For effective moisture control, position the fan close to the primary source of steam or humidity, such as above showers or near bathtubs. Ensure inlet and outlet ducts, if used, are correctly sized for a 100 mm connection and kept clear of obstructions. Periodic maintenance, including gentle cleaning of the grille and checking electrical connections, will help maintain performance and extend service life.
