DEF Frequently Asked Questions (FAQs)

Diesel Exhaust Fluid (DEF) is 32.5% solution of high-purity urea in de-mineralized water that is used with the Selective Catalytic Reduction system (SCR) to reduce emissions of nitrogen oxides (NOx) from the exhaust systems of diesel vehicles in the U.S. DEF is a clear non-hazardous liquid. It is not a fuel, nor a fuel additive and needs to be filled into a dedicated DEF tank, which is on your diesel vehicle. It is replenished in a similar way to refueling diesel. Should you spill DEF on your hands, simply wash it off with water. Click here for a DEF SDS for the U.S.

DEF needs to be protected from extreme temperatures. DEF’s freezing point is at 12 degrees Fahrenheit (-11 Celsius). When DEF thaws, the product will retain its initial quality and vehicles will remain operational throughout the DEF tank thawing process. DEF should be stored in a sealed package and in a well ventilated storage area.
DEF combined with Selective Catalytic Reduction (SCR) offers you a fuel efficient solution, with lower CO2 emissions then competitive solutions to adhere to the EPA Clean Air Act.  Most North American truck manufacturers offer SCR equipped models to meet these regulations. SCR is a proven technology to reduce nitrogen oxide, that brings diesel vehicles and fleet owners a payback with low maintenance and greater fuel economy.
DEF is a very pure product.  Any contamination will affect the quality of DEF, and this may cause your catalyst to need expensive repairs. To prevent contamination, it is imperative that foreign materials do not come in contact with the DEF solution. Use dedicated DEF tanks and dispensing equipment.  In the USA, DEF from Air1 is certified by the American Petroleum Institute to ensure DEF quality standards are maintained in accordance with ISO 22241 specifications. Buying Air1 DEF is a guarantee of the correct specification required for your SCR technology.
