Ventilation and filtration units
Comet Fans filtration and ventilation units for the rail sector are designed to ensure operational reliability, energy efficiency and protection of critical systems under demanding conditions. These solutions meet the needs of passenger trains, locomotives and high-speed trains, where thermal management and technical air quality are essential for safety.
These units are designed to ensure the protection of critical systems and ventilation under demanding operating conditions. Their main function is to ensure constant air exchange in technical compartments, removing dust and contaminants that could compromise the reliability of inverters, power electronics and traction systems.
- G4–F7 filters for coarse and fine dust.
- HEPA options for critical applications.
- Axial fans for high flow rates and confined spaces.
- Centrifugal fans for higher pressures and systems with significant pressure losses.
- Design optimised for rail technical compartments.
- Customisation options for specific layouts.
- 100% Tailor made
- Materials: anti-corrosion painted steel, with stainless steel options for aggressive environments.
