About us

Krapf & Lex filters protect against water/dust/snow/pressure shocks.

To prevent the penetration of dust, water and snow into the inside of vehicles, effective filter systems for fresh air and exhaust air of HVAC systems as well as for various cooling air systems of different technical components in locomotives and carriages are being developed and produced based on years of experience in close coordination with the customer.

Professional design and competent support by our engineers, starting from the first consultation until the fast provision of 3D models and samples, makes the integration of the components in the railway vehicles easy for our customers. Pressure protection systems are a very important issue for high-speed trains. Krapf & Lex constructs, based on several tested modules, reliable and low-maintenance solutions, which reliably prevent the occurrence of pressure differences in the inside of the vehicle. Krapf & Lex develops and produces several thousand solutions annually adjusted to particular customer requirements, which are used worldwide.

Ventilation grille

Ventilation grille

Our filters protect against water and dust. Every ventilation grille from Krapf & Lex gets adjusted individually to particular customer requirements. Our great variety of absorbing profiles makes possible construction depths of 40 mm up to 95 mm. With that, we reach good absorbing values even at high air speed. A complex adaptation to the interface given is a daily task for us. The very quick creation of 3D models for the engineering department of our customers is also one of our strengths.

Multi-cyclone separator

Multi-cyclone separator

The multicyclones from Krapf & Lex do have all the permissions necessary for railway vehicles such as the construction and production according to DIN EN 15085 or oscillation- and shock test according to DIN EN 61373.The multicyclone filter from Krapf & Lex is in use in desert areas. The fresh air for train staff and passengers is prepared by a pre-filtration designed by Krapf & Lex, before the air gets leaded, almost fully free of sand and dust, to the HVAC system.

Air grid combined with metalfilter

Air grid combined with metalfilter

The goal is to prevent the penetration of snow into the railway vehicle, but not to block the fresh air and exhaust air ducts with snow or ice. We work together with the leading European research institute in the sector snow.
Snow filter systems from Krapf & Lex have already proven themselves in the snowy regions in north Europe and alpine region. Our references are the Eurosprinter of Siemens for Lithuania, the Scandinavian trains, Metro Helsinki and Regina of Bombardier and the Flirt Stadler.
