Filters for the railway sector
In the railway sector, air filtration plays a strategic role: it ensures passenger comfort, staff health, protection of onboard systems, and the operational safety of the train.
HVAC systems in trains, subways, and trams must operate under particularly challenging conditions: the presence of fine dust, vibrations, temperature and humidity variations, and high concentrations of particles generated by brakes, rails, and electrical lines.
Typical applications
- Air conditioning of passenger carriages (rail HVAC)
- Driver cabins: protection of the operator from dust, fumes, and external agents
- Engine filters and auxiliary systems (compressors, onboard electrical systems)
- Battery ventilation and electrical panels
- Air filtration for braking systems
- Filtration for air-conditioning systems in stations and depots
Customer benefits
- Improved air quality for passengers and staff
- Reduction of fine dust (PM10, PM2.5, PM1) generated by brakes and tracks
- Protection of onboard equipment from particles and contaminants
- Service reliability thanks to fewer failures and simplified maintenance
- Compliance with European and international railway standards
- Energy efficiency and reduced operating costs
Types of filters for the railway sector
- Pre-filters and coarse filters (for dust and large particles)
- Medium and high efficiency filters (ISO 16890, ePM10, ePM2.5, ePM1)
- Activated carbon filters (for odours, gases, vapours, smog)
- Special fire-resistant filters (compliant with EN 45545:2020)
- Custom modular filters for railway HVAC systems
- Custom panel filters
Reference regulations
- EN 45545:2020 – Fire protection in the railway sector
- ISO 16890 – Air filter efficiency classification (fine particulate PM1, PM2.5, PM10)
- EN 779 (historical) – Replaced by ISO 16890, but still referenced in technical specifications
Specific features
Resistance to vibrations and shocks
Filters manufactured and certified according to railway standards for mechanical resistance.
Filtration class
ISO 16890 (ePM1, ePM2.5, ePM10), filters for sensitive areas such as driver cabins or high-speed trains.
Extended duration
Long maintenance intervals to reduce train downtime and operating costs.
Low pressure drop
Necessary to ensure energy efficiency and stability of HVAC systems.
Resistant materials
Fabrics and supports capable of withstanding vibrations, humidity, temperature variations, and flames (in accordance with fire safety regulations).
Regulations
Compliance with international railway standards such as EN 45545:2020 (fire protection).
Compatibility
Possibility to supply custom-made filters for different types of conveyors (regional trains, high-speed trains, subways).
