Filters for railway vehicles: Solutions for a cleaner mobility

We improve the air quality within rail vehicles, and protect heavy duty machinery and railway engines from harmful pollutants, whilst also reducing emissions in railway applications.

GET IN TOUCH

Every day, millions of people and goods travel across the globe. Fleet operators are faced with major challenges: railway applications must operate flawlessly under demanding conditions and high speeds 24/7. Any failures can very quickly translate into substantial costs and, often, a massive loss of trust. The air quality inside trains is also a critical factor: if air pollutants infiltrate the interior of rail vehicles via the air conditioning system or open windows, it can pose health risks to both employees and passengers. Moreover, the environmental dimension is also critical: rail vehicles can only maintain their status as the most sustainable mode of transportation if they continuously reduce their emissions – such as those from brake wear, for example – and fully comply with ever-evolving and increasingly demanding environmental regulations. However, a significant challenge is created by the limited supply of standardized solutions. As a result, there's an urgent need for customized products that execute their functions efficiently and effectively.

Filters for railway vehicles from MANN+HUMMEL effectively protect people, machinery and the environment from airborne and liquid contaminants, including oils and fuels. We provide tailored filtration solutions for both new constructions and retrofit projects. For existing fleets, we also offer catalog products, pre-adapted to the specific vehicle requirements, which helps ensure immediate usability.

Our product highlights at a glance:

Cyclone filters / cyclone separators Original Equipment

For decades MANN+HUMMEL has been developing and producing tailor-made air cleaner systems for a wide range of applications. From a simple air filter element with housing to complex air cleaner systems with dirty and clean side duct, safety element and dust pre-separator, a great deal is done to meet the needs of our customers.

Cabin air filters Original Equipment

Cabin air filter elements and systems from MANN+HUMMEL effectively protect vehicle users from pollutants and harmful gasses. Our cabin air filters make an impact with state-of-the-art HEPA H14 and other high-performance filters, molecular filters and biofunctional filters against mold growth.

EXPLORE

Fuel filters Original Equipment

Fuel filter modules from MANN+HUMMEL efficiently protect modern diesel injection systems. Besides a high level of dirt particle separation, the filters also convince with excellent water separation and thus reduce engine wear as well as the risk of damage from corrosion.

Bag filters Air Filtration

Our fine dust filters are used to separate airborne particles of the PM1, PM2.5 and PM10 fractions, which means they reliably and sustainably filter soot, cement dust, spores and larger bacteria. They typically feature either a mini-pleated filter media in a variety of frame shapes or are formed into bags in a bag filter.

Centrifuges / oil filters Original Equipment

Centrifuges from MANN+HUMMEL reliably separate soot particles from the engine oil and thus reduce engine wear. Thanks to numerous integrated functions, such as a pressure control valve or oil reservoir, MANN+HUMMEL centrifuges offer further advantages.

Filters for rail vehicles: Boosting train performance, while protecting health and the environment

MANN+HUMMEL crafts cutting-edge, high-efficiency filters and filtration systems for engines, interiors, and emission reduction. Our comprehensive filtration portfolio encompasses applications for all types of rail vehicles, from commuter trains and trams to high-speed trains - delivering integrated filtration solutions from a single source.

  • We protect railway engines against wear and tear with our top-tier air, fuel, and oil filters. In doing so, we help to optimize train performance while minimizing downtime, even under the most demanding conditions.
  • We ensure the safety of rail vehicles with our highly efficient filters and desiccant boxes for brake compressors.
  • With our cabin air filters for railway vehicles, we protect employees and passengers from airborne pollutants, including fine dust, viruses, bacteria, and pollen, as well as unpleasant odors.
  • We enhance the comfort of travelers' journeys with our innovative activated carbon system. This activated carbon matrix can be used in all the same applications as standard textile materials. The patent-protected material is applied under air-permeable textile surfaces of existing seating systems or wall coverings. It can be customized to specific needs and has impressive odor and moisture-absorbing properties.
  • We reduce emissions from rail vehicles with smart innovations like our brake dust filters, which can be easily fitted in the immediate vicinity of the source of emissions.
