Ducted fan AutoTune 125VKO — inline ventilation fan, model 125VKO

Ducted fan AutoTune 125VKO — inline ventilation fan, model 125VKO is an inline duct fan engineered for installation directly into ventilation ducts. The unit provides axial airflow for either extraction or supply in residential and light commercial environments. Its compact cylindrical body and straight-through airflow design allow placement in bathrooms, kitchens, utility rooms and short duct runs where continuous or periodic ventilation boost is needed.

Advantages

The fan is designed for easy inline mounting and delivers consistent axial airflow suitable for extract or supply configurations. Its compact form factor minimizes space requirements inside ductwork while maintaining reliable operation for continuous ventilation. The design reduces obstruction to airflow and is compatible with standard duct diameters, facilitating integration into existing systems. The balanced impeller and motor assembly contribute to stable performance and lower vibration during operation.

Suitable for

• Bathroom extraction to remove moisture and odors
• Kitchen ventilation for supplementary air removal
• Utility rooms and laundry areas requiring steady airflow
• Inline ventilation boost in short residential or light commercial duct runs

Key specifications

• Type: inline ducted axial fan for duct installation
• Application: extraction or supply ventilation in residential and light commercial spaces
• Form factor: cylindrical inline unit suitable for in-duct mounting
• Airflow direction: axial, straight-through flow
• Operation: continuous or intermittent duty depending on installation and control
• Typical installation: within round ductwork with coupling or clamp connection

How to use

Install the fan into the duct run following local electrical and building codes. Mount the unit so airflow direction matches the intended supply or extract function. Secure the fan with appropriate duct clamps or mounting brackets and seal connections to prevent leaks. Connect the electrical supply through a switched circuit or ventilation controller as required, ensuring correct voltage and protection. After installation, test the fan to confirm correct rotation, airflow direction and absence of unusual vibrations or noise.

Usage recommendations

Position the fan in an accessible section of duct for inspection and maintenance. Use suitable duct insulation and vibration-damping mounts where noise transfer or condensation is a concern. For prolonged continuous operation, follow local wiring and protection guidelines and schedule periodic checks of the impeller, motor and mounting points to maintain efficient performance.
