Overview Commercial vehicles, construction and agricultural machinery as well as industrial engines must operate reliably under demanding conditions. Variable fuel quality increases contamination risks. Fuel filters from MANN+HUMMEL protect modern diesel injection systems from particles and water droplets, ensuring clean fuel supply to the engine and extending component life.

Product types Fuel main filters from MANN+HUMMEL are available as spin-on fuel filters and as integrated filter modules. Spin-on filters offer standardized design, high pulsation resistance and pressure stability. MULTIGRADE filter media with different filtration efficiencies, sizes and service intervals can be combined with suitable filter heads to reduce system wear. Customized filter modules provide a high degree of functional integration and the WAVELOCK bayonet interface enables fast, clean and safe servicing.
