WHAT IS DEF?

DEF, or Diesel Exhaust Fluid, is a clear non-hazardous liquid that works with selective catalytic reduction (SCR) technology to convert harmful nitrogen oxide (NOx) from heavy-duty diesel vehicles into harmless nitrogen (N2) and water.

UFA sells the leading brand of high quality DEF, Air1^®, which is certified by the API™ to meet ISO 22241 standards for optimal engine performance.

WHY IS DIESEL EXHAUST FLUID IMPORTANT?

Modern diesel engines use DEF to generate cleaner exhaust and reduce harmful air pollution. In 2010 the Canadian American Environment Protection Agency (CEPA) introduced diesel emission standards that mandate the use of DEF in most commercial-grade diesel engines.
