Bathroom extractor fan ORNO BF-100/TS 100 mm surface-mounted with timer switch

ORNO BF-100/TS is a 100 mm surface-mounted bathroom extractor fan with an integrated timer switch designed to improve ventilation in bathrooms, toilets and small utility rooms. The compact unit extracts moist air and odors, reduces condensation on surfaces and supports general indoor air quality. Intended for visible mounting on walls or ceilings, the fan provides straightforward installation and maintenance in both residential and light-commercial settings.

Advantages

The fan’s compact 100 mm diameter design allows installation in limited spaces while maintaining effective airflow for small rooms. The built-in timer switch enables delayed shutoff, so ventilation continues for a preset time after the light or switch is turned off, ensuring more thorough removal of moisture and odors. Surface-mounted construction simplifies fitting without the need for recessed housing, and the device is designed for reliable continuous operation with low visual impact.

Suitable for

• Bathroom ventilation to reduce humidity and prevent mold
• Toilet rooms and small WC spaces
• Small utility rooms, laundry areas and storage spaces
• Renovation projects where surface-mounted installation is required

Key specifications

• Fan diameter: 100 mm
• Installation type: surface-mounted (wall or ceiling)

How to use

Install the ORNO BF-100/TS on a suitable solid surface following local electrical regulations and wiring practices. Connect the fan to a switched power supply so that the timer activates when the switch is turned off; set the desired delay time according to the installer’s or user’s preference. After installation, operate the fan by switching the room light or dedicated switch on; when the switch is turned off the timer will keep the fan running for the preset period to complete extraction. Regularly inspect the grille and impeller for dust build-up and clean as required to maintain airflow.

Usage recommendations

For effective moisture control, run the fan during and for several minutes after showering or bathing; ensure the unit is installed with appropriate air intake and exhaust paths and that ducts, if used, are properly sealed and vented to the exterior. Periodic cleaning of the external grille and internal fan components will help sustain performance and service life.
