The COR Series fans are designed to offer maximum compactness and high performance in confined spaces, thanks to the motor being installed within the airflow using an exclusive mounting system. In the rail sector, they are used for forced ventilation of critical components such as traction motors, converters, transformers and braking resistors, where effective cooling and a rational configuration are essential. The available impellers (straight, curved or aerofoil-profile blades) and materials (steel, stainless steel, aluminium) allow the product to be adapted to the noise and environmental resistance requirements typical of the rail sector, ensuring reliability even under demanding operating conditions.
