DEF Filters

With the growing adoption of Selective Catalytic Reduction (SCR) technology in modern diesel vehicles, maintaining the purity of Diesel Exhaust Fluid (DEF) is essential. Contaminants and poor-quality DEF filtration can cause injector clogging, pump failures - leading to system inefficiencies, increased downtime, and costly repairs. Using inferior quality DEF and DEF Filters can compromise the SCR system, forcing the vehicle into limp mode, reducing overall performance and failing to meet emission norms.

Why Choose Fleetguard DEF Filters?

Fleetguard DEF solutions are engineered with precision to provide superior DEF fluid filtration, ensuring clean DEF delivery and seamless functioning of your SCR selective catalytic reduction system.

With Fleetguard, you can be assured of: 

1. Cleaner DEF fluid, safeguarding injectors and pumps from clogs and damage

2. Prevents Engine derating

3. Helps to avoid costly SCR system repairs

4. Extends the life of your SCR system

Whether you're maintaining a commercial fleet or a single heavy-duty vehicle, using Fleetguard DEF solutions helps protect your investment and ensures compliance with emission regulations.

Comprehensive Filtration for Maximum Protection

  • Filling Neck Filters – Blocks contaminants during DEF refilling, ensuring only clean DEF enters the tank.
  • Level Sensor Filters - Protects the next-stage suction pump and dosing filter from blockages, extending their lifespan.
  • Dosing Unit Filters - Placed in the system line between the pump and the injector nozzle, these filters trap fine impurities that may form inside the DEF tank or lines. By preventing clogging of the injector nozzle, they ensure accurate DEF dosing, which is essential for efficient NOx reduction and emission compliance.

Applications: 

  • On-Highway Vehicles
  • Off-Highway Equipment
  • Passenger vehicles
