New tank vent filter from Parker Racor

ECO-Vent DEF filter designed to protect tanks and components from contamination 

PARKER Racor, part of Parker Hannifin – global leaders in motion and control technologies – have introduced a new tank vent filter to help keep diesel exhaust fluid (DEF) injection systems clean. 

Making use of DEF compatible proprietary engineered materials, the ECO-Vent filter prevents contaminated air from flowing into a tank, and incorporates a reservoir to collect dirt and water. Parker Racor say that by removing these impurities from the tank; it is possible to improve the reliability of the entire DEF injection system.

Many DEF tanks do not have specific filtration systems. The Racor ECO-Vent filter has, therefore, been specially developed to help reduce and prevent contamination in these potential problem areas. 

For operators and maintainers, the filter is said to provide quick installation, tool-free servicing and easy element replacement by incorporating patented, flexible tabs that allow the filter to ‘snap’ into place.

When a vehicle engine is running, and selective catalytic reduction (SCR) is active, the ECO-Vent draws contaminated air into the bottom of the filter, as DEF is used. The filter then traps any fine contaminants and any collected water is returned to the reservoir before draining out. 

To improve reliability, the ECO-vent’s mounting bracket is manufactured from E-coated steel to help resist the sort of corrosion that can be caused by DEF or wider environmental factors. 

The filter has also passed ISO 5011 air filtration testing, thermo-cycling, vibration testing and Urea compatibility testing. It is advised that the ECO-Vent should be replaced once a year to deliver strong reliability.
