Why DEF is Important?

Emissions

DEF reduces Nitrogen Oxide (NOx) emissions. Nitrogen oxide is a harmful gas that can damage the human respiratory system, reducing lung function, increasing allergen exposure, and the risk of respiratory illnesses. DEF protects vegetation, reduces acid rain, and supports cleaner air, contributing to the preservation of ecosystems and compliance with stringent emission standards.

Meets Emission Standards

DEF helps diesel vehicles meet the strict guidelines set by the EPA (Environmental Protection Agency). Without DEF, a diesel engine's performance and efficiency would decline. By substantially reducing NOx emissions, DEF ensures that heavy machinery and trucks meet the stringent guidelines set by the EPA.

Keeps the Vehicle Running Smoothly

DEF is essential to keeping a diesel vehicle up and running.

How Much It Reduces NOx Emissions?

It achieves a remarkable 85 – 95% reduction in NOx emissions.

Vehicle	Without DEF	With DEF
Truck	860 Gg	129 Gg
Bus	680 Gg	102 Gg
Pickup	111 Gg	22 Gg
Car	17 Gg	3 Gg
