Advanced filtration systems designed for Diesel Exhaust Fluid (DEF/urea) applications, protecting SCR
systems from contaminants, ensuring optimal emission control, and extending system life across
automotive, commercial, and industrial machinery.
What Are Urea Filters?
Urea filters are essential components in Diesel Exhaust Fluid (DEF) systems, removing impurities
from urea solutions to protect SCR catalysts, dosing pumps, and injector nozzles. Clean DEF ensures
proper NOx reduction, improves engine performance, and prolongs system life in vehicles and
industrial equipment.
🔧
System Protection
Filters safeguard SCR catalysts, dosing pumps, and injectors from contaminants like dirt,
sediment, and crystals, reducing maintenance and ensuring reliable operation.
⚙️
Consistent DEF Flow
Maintains steady DEF supply to the SCR system, ensuring efficient NOx reduction, smooth
engine operation, and compliance with emission regulations.
🛡️
High Contaminant Capacity
Specialized media removes microscopic impurities without restricting flow, ideal for
high-demand engines, long intervals between maintenance, and heavy-duty operations.
💧
Fluid Integrity & Stability
Prevents DEF crystallization and contamination, ensuring proper chemistry, longer system
life, and reduced downtime in fleet or industrial applications.
