Since 1399, Adak Sanat Polymer has been the sole manufacturer of diesel after treatment systems in Iran and its products, such as DOC, DPC and SCR, have been used in more than 10 thousand vehicles.

Up to the year 1397, this company imported various kinds of diesel filters and catalysts as the exclusive representative of the Korean company Ceracomb. Through recruiting young and talented experts and after improving its infrastructure, which was made possible by the support of national vehicle manufacturers, Adak Sanat Polymer started the process of indigenizing the products it used to import. After acquiring the technology and equipping the company, the first production line of diesel after treatment filters were launched in Iran to meet the needs of the countries industry.
