CNX Series

Comet Fans CNX Fan Series for Marine Applications

Comet Fans CNX fans are designed to ensure stable and reliable airflows in onboard ventilation and cooling systems. Thanks to their robust construction and aerodynamic optimisation, they ensure energy efficiency, low noise levels and long service life even in marine environments characterised by humidity, salt exposure and demanding operating conditions. Available in direct-drive or belt-drive configurations, they are suitable for engine rooms, technical spaces and auxiliary systems, contributing to the safety and operational continuity of naval/marine units.
