Description
EC centrifugal box fan VN-Box EC
The VN-Box EC is a direct-driven centrifugal box fan with an energy-efficient EC-IE5 motor and integrated controller. It is suitable for moving air in a wide range of ventilation applications and offers extensive configuration options to meet the required airflow and pressure.
With sizes ranging from 350 to 630 mm, airflow rates of up to 16,000 m³/h and pressure capabilities of up to 1,100 Pa, the VN-Box EC is suitable for a wide range of applications. Multiple discharge positions are also available, allowing the fan configuration to be adapted to the installation layout and connection requirements.
When should you choose a box fan?
A box fan is a suitable choice when air needs to be moved using a fan integrated into an enclosed housing. The box construction offers flexibility for installation in various ventilation arrangements and technical systems.
The VN-Box EC can be used for applications including:
- Air supply and extraction in buildings
- Ventilation in commercial premises, workshops and production environments
- Ventilation of technical rooms
- Air movement in air handling and ventilation systems
- Technical applications with specific airflow and pressure requirements
The most suitable configuration depends on the required operating point, the installation and the conditions in which the fan will be used.

Energy-efficient EC-IE5 motor with integrated controller
The VN-Box EC is direct-driven by an EC-IE5 motor with IP55 protection. The integrated controller allows the fan speed to be adjusted to suit the required airflow.
Available control options include:
- 0–10 V DC
- 4–20 mA DC
- PWM
- RS485/Modbus
The fan is available with a power supply of 230 V single-phase or 400 V three-phase, at 50 Hz.
Adjusting the fan speed to match the required airflow allows the fan to be configured for the application. Explore our full range of EC fans for more designs featuring energy-efficient EC motor technology.
Housing and discharge positions
The housing consists of galvanised steel panels with aluminium profiles. Multiple discharge positions are available, allowing the box fan to be configured to suit the installation layout.
The most suitable version depends on factors such as the available installation space, duct connections and required operating point.
Accessories and configuration options
Depending on the application, the VN-Box EC can be supplied with various accessories, including:
- Protective grille
- Weather hood
- Mounting feet
- Vibration dampers
- Filter section
- Isolator switches
- Temperature control
The available combinations and configurations allow the fan to be adapted to the technical requirements of the installation.
Selecting the right VN-Box EC
When selecting a VN-Box EC, we consider factors including:
- The required airflow in m³/h
- The required pressure in Pa
- The resistance of ductwork, filters and other installation components
- The type and temperature of the air to be moved
- The available space and required discharge position
- The supply voltage and preferred control method
- The required accessories
A range of designs and configurations is available to achieve the required operating point. If a standard version does not fully meet the requirements of your application, we will be happy to explore the available customisation options.
Do you already have a calculated operating point or technical data for the installation? We can use this information to select a suitable version. If you do not have all the details yet, you can still contact us to discuss your application.
