Diesel Exhaust Fluid (DEF), the USA operating fluid for SCR is a non-toxic solution that transforms harmful Nitrogen Oxide (NOx) emissions from America's diesel-powered vehicles into harmless water vapor and nitrogen. 

Diesel Exhaust Fluid supplier for the USA, Yara, is the American producer of the Air1 brand which brings quality Diesel Exhaust Fluid (DEF) solutions to the US market.  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.
