Air1®, the Reliable Quality Diesel Exhaust Fluid Solutions for All SCR Fleets

New truck engine manufactures will comply with the new emission standards impose by the EPA Clean Air Act that came into effect on January 1st 2010.  Under the new regulations, most engine manufacturers have chosen the Selective Catalyst Reduction (SCR) system as the most efficient way to meet these clean air standards.  Diesel Exhaust Fluid (DEF), the operating fluid for SCR is a non-toxic solution that transforms harmful Nitrogen Oxide (NOx) emissions from diesel-powered vehicles into harmless water vapor and nitrogen.  According to engine manufacturers, SCR combined with DEF improves overall fuel economy by approximately 5% compared to competing technologies, and achieves NOx reductions in excess of 90%.
