Filtration Considerations

Long over-the-road service intervals demand high-capacity filters with proven β-ratios
Modern SCR/DPF/EGR aftertreatment systems require ultra-clean intake air and ultra-low-SAPS lubricants
CNG and LNG fuel systems need specialized filter media — different from diesel fuel filtration
Engine brake and exhaust back-pressure regimes stress oil filtration — bypass filtration is recommended
Road dust vs. dust-free highway corridors produce very different air-filter loading profiles
