Inline duct fan AWENTA WKA fi125 205 m³/h 16 W 230 V with timer switch white

AWENTA WKA fi125 is an inline duct fan designed for compact ventilation installations. The unit delivers a nominal airflow of 205 m³/h while consuming 16 W on a 230 V supply and is intended for connection to Ø125 mm ducts. The fan includes a built-in timer switch for delayed shutdown, enabling continued extraction after the controlling light or switch is turned off. Its white finish and cylindrical inline form factor allow discreet integration into bathroom, kitchen or small-system ventilation routes.

Advantages

The inline configuration reduces noise in occupied rooms by placing the motor inside the duct line and shortens installation between source and outlet. Low power consumption (16 W) provides energy-efficient continuous or intermittent operation. The integrated timer switch simplifies control without requiring additional electronics and permits a selectable delay to clear residual humidity or odors. The fan’s compatibility with Ø125 mm ducting and standard 230 V mains makes it suitable for retrofit and new build installations.

Suitable for

• Bathroom extraction for improved humidity control
• Kitchen ventilation for local grease and odor removal
• Small residential ventilation systems and duct runs with Ø125 mm connections
• Toilet rooms, utility rooms and laundry areas requiring intermittent extraction

Key specifications

• Nominal airflow: 205 m³/h
• Power consumption: 16 W
• Supply voltage: 230 V
• Duct connection diameter: 125 mm (Ø125)
• Built-in timer switch for delayed shutdown
• Inline cylindrical design, white finish

How to use

Install the fan inline in the ventilation ducting with the airflow direction aligned to the arrows on the housing. Connect to a 230 V supply following local electrical regulations; the built-in timer switch is typically wired to the same control circuit as the room light or separate switch. Set the desired delay on the timer so the fan continues to run for the required period after the switch turns off. Ensure duct joints are sealed to prevent air leaks and mount supports to avoid vibration transfer to the building structure.

Usage recommendations

For reliable operation, maintain clean ductwork and periodic inspection of the fan and timer. Use suitable vibration-damping mounts and keep the fan accessible for servicing. When installed in bathrooms or kitchens, select a timer delay that allows complete removal of humidity or odors without excessive run time to balance ventilation effectiveness and energy use.
