We designed a self-reverse-blowing, high-temperature-resistant black smoke filter (metal DPF). This metal DPF utilizes imported black smoke filter material, offering high-temperature resistance, low backpressure, a long lifespan, reasonable cost, and long-term maintenance-free operation (maintenance every 6-12 months). Utilizing an advanced rapid regeneration principle, the filter element rapidly regenerates (in less than 1 second per cycle), automatically collecting black smoke and instantly restoring the filter element to a low-resistance state.
