SCR Urea Systems

GVS utilized its vast expertise in injection technology for the fuel system to apply to the application of injector filters in the SCR system.

Common to both systems, in the SCR there are injector nozzles used to spray the Dosing Fluid into the exhaust stream.

Without fluid filters the nozzle may become clogged with debris. The SCR injector filter is designed to remove this debris before the dosing fluid flows to the nozzle.

GVS is also specialized in SCR Pump Filters.

With our wide range of media efficiency from 10mic to 70mic, GVS filters protect the DEF/Urea dosing pump with a low pressure drop and a high dust holding capacity, allowing an unlimited number of freezing-thawing cycles.
