Ventilation duct fan AWENTA Awentis AW125 hybrid system Ø125 mm, model AW125

AWENTA Awentis AW125 hybrid system Ø125 mm is a duct-mounted ventilation fan designed for use in mechanical and hybrid ventilation installations. Intended to be fitted into Ø125 mm ducts, the unit supports air extraction and assisted airflow in residential and light-commercial settings, improving air exchange and indoor air quality when integrated with existing ductwork and ventilation controls.

Advantages

The fan combines compact dimensions with compatibility for standard 125 mm ductwork, allowing straightforward in-line installation. Its hybrid design supports both continuous mechanical operation and demand-controlled ventilation when connected to timers, humidity sensors or building management systems. Constructed for duct integration, the unit minimizes installation footprint and provides reliable airflow performance suitable for bathrooms, kitchens and utility spaces.

Suitable for

• Extraction of stale or humid air from bathrooms and shower rooms
• Ventilation of kitchens and small cooking areas
• Support of airflow in ventilated utility rooms and storage spaces
• Integration into hybrid residential ventilation systems with Ø125 mm ducts

Key specifications

• Connection diameter: 125 mm suitable for standard round ducts
• Mounting type: in-line/duct-mounted installation
• Application: designed for extraction and assisted airflow in residential and light-commercial premises
• Design: hybrid operation compatible with mechanical continuous or demand-controlled setups
• Compatibility: intended for integration with ductwork and external control devices (timers, sensors)

How to use

Install the AWENTA Awentis AW125 directly into a Ø125 mm ventilation duct following local building codes and electrical safety requirements. Position the unit in the duct run to provide effective extraction from the target room and ensure airflow direction matches the fan’s orientation markings. Connect electrical supply and any external controllers such as timers or humidity sensors according to the manufacturer’s wiring diagrams. After installation, verify airtight duct connections and test the unit across its operating modes to confirm correct airflow and control response.

Usage recommendations

For optimal performance, use the unit with matched Ø125 mm ducting and minimize sharp bends or long duct runs that can reduce airflow. Where humidity control is required, pair the fan with a humidity sensor or timer to enable demand-driven operation. Ensure periodic inspection of duct connections and cleaning of intake/exhaust paths to maintain airflow efficiency.
