Diesel Exhaust Fluid reduces NOx emissions in the exhaust gas system of your SCR equipped diesel vehicle, be it a truck, a bus, a tractor, a car, a van or an off road vehicle. The Air1 brand offers not only the Diesel Exhaust Fluid (DEF) product in itself but also a full range of related US Diesel Exhaust Fluid storage and handling equipment to meet all North American fleet operators and individual requirements.
Diesel Exhaust Fluid and SCR, according to engine manufacturers, improves overall fuel economy by approximately 5% compared to competing technologies, and achieves NOx reductions in excess of 90%. New truck engine manufactures will comply with the emission standards imposed by the EPA Clean Air Act that came into effect on January 1st 2010. Under the new US regulations, most engine manufacturers have chosen the Selective Catalytic Reduction (SCR) system as the most efficient way to meet these clean air standards.
