Pneumatic cleaning involves using compressed air to remove the buildup of soot and other particles from the DPF, DOC, SCR and One Box. The process typically involves removing the filter from the engine and then using a specialized machine to blow compressed air through the filter in a reverse direction, effectively blasting out the accumulated material. 

One advantage of pneumatic cleaning is that it is a relatively quick and efficient method of cleaning DPF, DOC, SCR and One Box, which can help to minimize downtime for vehicles or equipment that rely on diesel engines. It is also a non-invasive method of cleaning that does not require the use of chemicals or other potentially harmful substances. 

Aqueous cleaning typically involves soaking the DPF, DOC, SCR and One Box in a solution of water and detergent or other cleaning agents, which helps to loosen and dissolve the buildup of soot and other particles. The filter is then rinsed thoroughly with water to remove any remaining contaminants. 

One advantage of aqueous cleaning is that it can be a very effective method of cleaning DPF, DOC, SCR and One Box, particularly if the filter has become heavily clogged with soot and other particulate matter. The use of cleaning agents can help to break down the buildup of contaminants, while the use of water can help to flush them out of the filter. 

Thermal cleaning typically involves placing the DPF, DOC, SCR and One Box,  in a specialized oven or furnace, which is then heated to temperatures ranging from 500 to 700 degrees Celsius (932 to 1292 degrees Fahrenheit) or higher. The high temperatures cause the soot and other contaminants to burn off, leaving the filter clean and restored to its original capacity. 

One advantage of thermal cleaning is that it can be a very effective method of cleaning DPF, DOC, SCR and One Box, particularly if the filter has become heavily clogged with soot and other particulate matter. The process can help to remove even the most stubborn contaminants, and can be particularly effective for removing ash, which is a byproduct of engine oil and
