Delivering Clean Diesel Exhaust Fluid to Keep You Running

Supplier: Donaldson Filters

Introducing a filter from Donaldson Clean Fuel and Lubricant Solutions for bulk Diesel Exhaust Fluid (DEF) that provides unsurpassed filtration efficiency and industrial quality construction to protect your vehicles and equipment so you can achieve more.

Price Guide: POA

Today's Selective Catalytic Reduction (SCR) systems require clean DEF for precise dosing and complete atomisation to occur. Without clean DEF, the SCR cannot do its job of transforming NOx into harmless nitrogen and water.

Contamination from handling practices during transfer and storage or incompatible material corrosion can prevent you  from accessing the clean DEF you need to Achieve More. Problems with the fluid can occur, and onboard equipment can plug due to the presence of particulate and crystals.

The Donaldson DEF filter catches dirt before it reaches the onboard DEF filter, thereby ensuring the proper function of the SCR, extending the life of the onboard DEF filter and preventing vehicle or equipment power reduction.
