Wheel loaders are one of the construction vehicles. With the nature of working regularly with large loads, the engine used for wheel loaders is usually a diesel engine. Like all other diesel-powered vehicles, wheel loaders are required to use additional diesel exhaust treatment machines to remove maximum dust particles and exhaust gases, providing better protection for the environment as well as workers.

To meet that practical requirement, the Dr.Air DS-7L diesel engine exhaust treatment machine for wheel loaders was born. The product is designed to be small, compact, simple, and easy to integrate with diesel engines. In particular, with the combination of DPF and DOC treatment technology, Dr.Air DS-7L effectively treats exhaust gas up to 90%.

Diesel engine exhaust gas treatment machine model

According to the analysis results of scientists, exhaust gas generated from diesel engines includes many chemical compounds, typically NOx, HC, CO, … in addition to fine dust – a dangerous agent that irritates the respiratory tract in humans.

To ensure effective exhaust gas treatment, diesel engine exhaust gas treatment equipment is integrated with many treatment technologies. Initially, exhaust gas is sent to the DPF processor. With a honeycomb structure and particulate filter, this technology quickly adsorbs and captures fine dust. The exhaust gas stream containing chemical compounds then goes to the DOC unit. Here, metal catalysts create chemical reactions, turning these substances into environmentally friendly substances, safe for humans.

The process of treating diesel engine exhaust gas of Dr.Air DS-7L wheel loader is relatively simple, does not require high technical expertise from the operator. For more specific advice on the product, customers please contact Dr.Air directly via hotline 1900.4790.
