Diesel Exhaust Fluid (DEF), the operating fluid for SCR vehicles, is a non-toxic solution that transforms harmful Nitrogen Oxide (NOx) emissions from diesel-powered vehicles into harmless water vapor and nitrogen. DEF reduces NOx emissions in the exhaust gas system of your SCR equipped diesel vehicle. Air1 complies with the highest industry standards in DEF, certified by American Petroleum Institute (API). You can be sure your SCR vehicle will function flawlessly by using Air1 DEF. We reliably supply the highest quality DEF via the Mansfield DeliveryONE Network of distributors across the US, so you are never far away from an Air1 distributor.
