The system operates using an alternating process of water flushing and high-pressure air purging. High-pressure air stored in the pressure tank is released instantaneously. This release compresses the water, converting it into powerful kinetic energy that forces contaminants out of the honeycomb substrate. During the cleaning cycle, circulating water thoroughly fills the DPF housing and honeycomb channels from the bottom up. When high-pressure air is rapidly discharged, the pressurized water expels accumulated deposits—such as hydrogen sulfate and ammonium bicarbonate compounds—from deep within the honeycomb structure, restoring optimal filter performance.
