Bathroom fan ORNO BF-100/PS 100 mm surface-mount with on/off switch

ORNO BF-100/PS 100 mm surface-mount bathroom fan with on/off switch is a compact ventilation unit designed for small bathrooms, toilets and utility rooms. The fan features a 100 mm diameter impeller and a surface-mount housing that allows quick installation on walls or ceilings where recessed ducting is not practical. The integrated on/off switch provides simple manual control for intermittent ventilation to reduce moisture and odors in residential spaces.

Advantages

The surface-mounted design eliminates the need for deep wall cavities or complex duct connections, making installation faster and suitable for retrofit projects. A 100 mm impeller size ensures adequate airflow for small rooms while keeping noise and energy consumption low. The built-in on/off switch provides straightforward operation without additional wiring for remote controls, and the compact housing fits neatly into limited spaces.

Suitable for

• Small bathrooms and guest toilets
• Utility rooms and laundry areas
• Closets or small service rooms requiring occasional ventilation
• Retrofit projects where surface mounting is preferred

Key specifications

• Fan diameter: 100 mm impeller
• Mounting type: surface-mount for wall or ceiling installation
• Control: integrated manual on/off switch
• Application: intermittent extraction for moisture and odor control in small residential rooms
• Installation: suitable where inline ducting is limited or not required

How to use

Mount the unit on a flat wall or ceiling surface using appropriate fixings for the material. Connect the fan to a dedicated power supply following local electrical regulations and the product wiring diagram. Use the integrated on/off switch to operate the fan during and after showering or other activities that generate moisture or odors. Ensure the air outlet is not obstructed and that any short duct run or grille is kept clear for efficient extraction.

Usage recommendations

For best performance, place the fan close to the moisture source and ensure adequate room air replacement. Periodically check and clean the grille and impeller to maintain airflow and reduce noise. If continuous ventilation or higher airflow is required, consider a larger or ducted model.
