Hydrogen as an energy source for fuel cells or combustion engines offers the possibility of making transportation with Passenger cars, heavy commercial vehicles and the off-highway sector CO2-neutral. This results in new requirements for filtration systems that differ considerably from those of conventional diesel engines and in some cases go far beyond the current level. With a modular system of specially developed and flexible filtration solutions, Hengst is creating the basis for the efficient and climate-friendly use of hydrogen in combustion engines and fuel cells. Hengst also offers pioneering filtration technology for electromobility, such as the electrified cabin air filter, which sets new standards in filtration and durability.
