EC Plug Fan – VN-Plug EC
The VN-Plug EC is an energy-efficient EC plug fan with backward-curved blades, designed for air handling and ventilation systems. It features an EC motor with stepless speed control via a 0–10 V signal. With airflow rates of up to 60,000 m³/h and pressures of up to 2,000 Pa, the VN-Plug EC is suitable for a wide range of applications requiring efficient, controllable airflow.
The plug fan is installed directly into an air handling unit, ventilation unit or other air handling system. The compact version is available up to size 630, while larger versions are supplied with a frame up to size 1,120.
What is an EC plug fan used for?
A plug fan is a practical choice when the fan needs to be integrated into a larger air handling system. As the VN-Plug EC can be installed without a conventional fan housing, it offers flexibility in system design and installation.
The VN-Plug EC can be used in applications such as:
- Air handling units (AHUs)
- Ventilation and air handling systems
- Data centre cooling and cooling air systems
- Industrial ventilation
- Process ventilation and air movement
- Supply and extract air systems
- Other installations requiring controllable airflow
The most suitable version depends on factors such as the required airflow rate, system resistance, available installation space and preferred control method.
Energy-efficient performance with EC technology
The VN-Plug EC is equipped with an EC motor. Its speed can be adjusted steplessly via a 0–10 V control signal, allowing the airflow rate to be matched to the actual ventilation demand.
The standard motor is available in 230 V / single-phase / 50 Hz versions up to and including 1.1 kW. For higher power ratings, a 400 V / three-phase version is available. An EC controller is included with the fan.
The VN-Plug EC is one of our EC fans for applications where energy efficiency and controllable airflow are important.
Compact version or version with frame
The VN-Plug EC is available in two configurations.
The compact version is available in sizes 225 to 630. It is designed for space-efficient integration into applications such as air handling units and ventilation units.
For larger installations, the VN-Plug EC is also available with a frame, in sizes 225 to 1,120. This allows a suitable plug fan to be selected for applications requiring higher airflow rates.
The fans are balanced to G2.5 in accordance with ISO 1940.

EC plug fan or another centrifugal fan?
The VN-Plug EC is a specific type of centrifugal fan in which the impeller can be integrated directly into an air handling system. Looking for a different configuration, such as a centrifugal fan with a housing, different pressure or airflow capabilities, or another motor type? Explore our range of centrifugal fans.
Our range of EC fans also includes other configurations for applications where energy efficiency and speed control are important.
Selecting the right plug fan
A plug fan should be selected based on the required duty point: the combination of airflow rate and pressure required by the installation. The fan’s maximum airflow capacity alone is therefore not enough to determine whether it is suitable.
Available installation space, power supply, control method and the way the fan is integrated into the system must also be taken into account.
Have you already determined the required duty point? We can use this information to select a suitable VN-Plug EC. If you do not yet have all the details, feel free to contact us. We are happy to help you select the right fan for your application.
