EC centrifugal roof fan VN-Roof CHM EC
The VN-Roof CHM EC is a centrifugal roof fan with horizontal discharge, an energy-efficient EC-IE5 motor and an integrated controller. It is designed for extracting air through the roof of a building. With diameters ranging from 310 to 630 mm, it offers airflow rates of up to 16,500 m³/h and pressure capabilities of up to 1,100 Pa. The integrated controller allows the fan speed and airflow to be adjusted to the requirements of the application.
When should you choose a centrifugal roof fan?
A centrifugal roof fan is suitable when air needs to be extracted through the roof and sufficient pressure is required to overcome resistance within the installation, such as that caused by ductwork or filters.
Typical applications include:
- Extracting air from commercial and industrial premises
- Ventilation in workshops and warehouses
- Removing warm air from buildings and technical rooms
- Industrial ventilation and process extraction
- Ducted ventilation and air treatment systems
- Commercial buildings and utility facilities
- Technical installations where the fan forms part of a larger system
The right fan depends on the required airflow, pressure and operating conditions.
Horizontal discharge through the roof
The VN-Roof CHM EC discharges air horizontally. This configuration can be suitable for applications where extracted air needs to be discharged sideways above the roof.
The fan can be used as a standalone unit or as part of a larger ventilation installation, depending on the requirements of the application.
Energy-efficient EC-IE5 motor with integrated controller
The VN-Roof CHM EC features an energy-efficient EC-IE5 motor with IP55 protection. Its integrated controller allows the fan speed to be adjusted to suit the required airflow.
Available control signals include:
- 0–10 V DC
- 4–20 mA DC
- PWM
- RS485/Modbus
The fan is available with a 230 V single-phase or 400 V three-phase power supply, at 50 Hz.

- Connection boxes
- Temperature controllers
The available configuration depends on the specific requirements of the application.
VN-Roof CHM EC or another roof fan?
The VN-Roof CHM EC is a centrifugal roof fan with horizontal discharge. It is suitable for applications where air needs to be extracted through the roof and adjustable airflow and sufficient pressure are required.
Our range of roof fans also includes other designs, such as axial roof fans and roof fans for ATEX applications. The most suitable fan depends on factors including the required airflow and pressure, the properties of the air being extracted and the operating conditions.
Not sure which design is right for your application? We are happy to help you select a suitable fan.
Selecting the right roof fan
When selecting a VN-Roof CHM 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 extracted
- The available space and roof structure
- The supply voltage and preferred control method
- The required accessories
We also help you select the right configuration for specific technical applications and non-standard requirements. 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.
