Rail transport relies on collective mechanics where every link in the network counts: shunting locomotives, maintenance trains, maintenance trainsets and catenary intervention vehicles. Subject to dust, vibrations, temperature variations and intensive usage cycles, this equipment must remain reliable regardless of operating conditions. The continuity of the network depends largely on the availability of these maintenance machines. A technical failure or unplanned shutdown can delay operations, disrupt train traffic and generate significant costs. In this context, filtration becomes an essential lever for ensuring the performance and safety of railway equipment. HIFI FILTER® supports industry players with a comprehensive range covering all critical maintenance machine systems. This comprehensive approach ensures technical compatibility, traceability and consistent operation across all equipment used on the network.
Safety and compliance: protecting operators and machinery
Railway maintenance equipment operates in environments where personnel safety and regulatory compliance are inseparable. To meet these requirements, HIFI FILTER® designs its solutions in accordance with the main industry standards.
Fire protection
The EN 45545-2 standard defines the requirements relating to the fire behaviour of materials used on board vehicles: their ability to ignite, spread flames and emit smoke or toxic gases. Filters intended for cabins or technical compartments are directly affected. They must be designed to limit the spread of flames and reduce the toxicity of emissions in the event of an incident. To this end, HIFI FILTER® develops specific filter media with low flame spread and low harmful gas emissions.
Performance standard
The ISO 16890 standard, dedicated to air quality, defines the performance of cab and ventilation filters. Class ePM1 filters capture more than 85% of fine particles and ensure healthier air, even in environments exposed to diesel emissions. Safety does not stop at the cabin: it also concerns hydraulic circuits, compressed air networks and fuel systems. By controlling contamination at these sensitive points, filtration protects both the machines and the people who use them.
Predictive maintenance: monitoring for better planning
Advances in maintenance technology are transforming the way operators manage their equipment. Filtration plays a key role in this transition, as fluid quality and filter condition are good indicators of a machine's overall performance. By monitoring contamination levels, differential pressures or clogging rates, it becomes possible to assess component wear before it causes a breakdown. This data facilitates the implementation of predictive maintenance plans, where interventions are triggered based on the actual condition of the system rather than a fixed schedule. HIFI FILTER® filters are designed to be integrated into these monitoring and diagnostic programmes. This approach enables railway operators to improve the availability of their equipment, optimise their maintenance cycles and enhance the reliability of the network.
“Did you know? Every unplanned stoppage of a railway vehicle represents a significant cost, often between €500 and €1,000 per hour, depending on the type of intervention and operating penalties.“
