EC Compact Axial Wall Fan – VN-Wall EC-C
The VN-Wall EC-C is an axial wall fan equipped with an energy-efficient EC motor. It is designed for extracting or supplying air in rooms and buildings where efficient, controllable airflow is required.
The VN-Wall EC-C is available in diameters from 200 to 630 mm, with airflow rates of up to 12,000 m³/h and pressure capabilities of up to 200 Pa. Thanks to its EC motor, the fan speed can be adjusted accurately and easily, for example via a 0–10 V control signal or direct online control.
What is an EC wall fan used for?
A wall fan is installed directly in an external or internal wall to extract air from a space or supply fresh air from outside. The VN-Wall EC-C is suitable for a wide range of ventilation applications where an extensive ductwork system is not required.
Typical applications include:
- Production facilities and commercial premises
- Workshops and warehouses
- Agricultural buildings
- Plant rooms and technical spaces
- Industrial ventilation
- Extraction of warm or humid air
- General air supply and extraction
The right version depends on more than the required airflow rate. Available pressure, wall opening dimensions and the preferred control method must also be taken into account.
Energy-efficient performance and precise speed control
The VN-Wall EC-C features an EC motor. Its speed can be adjusted easily, allowing the airflow rate to match the actual ventilation demand.
The fan can be controlled via 0–10 V. Depending on the application, other control options may also be available, including a potentiometer, PWM signal, Modbus, or control based on temperature or humidity.
This makes the VN-Wall EC-C a suitable choice for applications where the fan does not need to operate continuously at full capacity.
The VN-Wall EC-C is one of our EC fans for energy-efficient, controllable airflow.
Available sizes from 200 to 630 mm
The VN-Wall EC-C is available in various diameters. Depending on the version, maximum airflow rates range from 950 to 12,060 m³/h.
- VN-Wall EC-C 200: up to 950 m³/h
- VN-Wall EC-C 250: up to 1,700 m³/h
- VN-Wall EC-C 300: up to 2,430 m³/h
- VN-Wall EC-C 350: up to 3,420 m³/h
- VN-Wall EC-C 400: up to 4,970 m³/h
- VN-Wall EC-C 450: up to 5,890 m³/h
- VN-Wall EC-C 500: up to 9,710 m³/h
- VN-Wall EC-C 630: up to 12,060 m³/h
Maximum airflow capacity is not the same as the fan’s available duty point. The appropriate version is selected based on the required airflow rate and the resistance in the application.
Full technical specifications and performance curves are available in the product datasheet.
Wall fan with steel housing
The VN-Wall EC-C features a coated steel housing and an EC motor with IP44 or IP54 protection, depending on the version. Air flows from the motor towards the impeller.
Various accessories are available for different applications, including:
- Protective grilles
- Dampers
- Isolator switches
- Speed controllers
- Temperature and humidity controllers
These options allow the wall fan to be adapted to the installation requirements and preferred control method.
VN-Wall EC-C or another axial fan?
An axial wall fan is particularly suitable when air needs to be moved directly through a wall. If the fan is part of a ductwork system, an EC axial duct fan may be a better choice.
Various configurations are available within our EC fan range. The choice between a wall fan, duct fan or another EC fan depends on the required duty point and how the fan will be used in the installation.
Selecting the right EC wall fan
Choosing the right VN-Wall EC-C involves more than just selecting the diameter. We consider factors such as:
- Required airflow rate in m³/h
- Required pressure in Pa
- Available installation space
- Wall opening dimensions
- Preferred control method
- Power supply
- Operating conditions
