Detailed structure

Dr.Air DS-5L Diesel engine exhaust catalyst filter consists of two main parts: DOC filter (Oxidation Catalyst) and DPF filter (Particle Trap).
DOC filter (Oxidation Catalyst)

• Size: φ305 x 100 mm
• Function: Use catalytic technology to convert pollutants such as CO, NOx, HC into less toxic substances such as CO2 and H2O.

DPF (Particulate Trap) Filter

• Dimensions: φ305 x 254 mm
• Function: Use honeycomb ceramic structure to capture fine dust particles in exhaust gas, helping to reduce air pollution.

Working principle of Dr.Air DS-5L diesel engine exhaust catalyst .

Dr.Air DS-5L Diesel Engine Catalytic Converter for Road Rollers operates based on the combination of two technologies DOC (Oxidation Catalyst) and DPF (Particulate Trap). When the diesel engine is running, the exhaust gas is led into the filtration system.

First, the exhaust gas passes through the DOC filter, where pollutants such as hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) are converted into carbon dioxide (CO2) and water (H2O) through oxidation. The exhaust gas then passes through the DPF filter, where fine particulate matter (PM) is trapped in the filter’s honeycomb ceramic structure. Finally, the treated exhaust gas is released into the environment, minimizing pollution impacts and making it safer for human health.

Advantages of Dr.Air DS-5L diesel engine exhaust catalyst for road roller
