This AdBlue filter is installed in the exhaust system of the host tractor or combine. It removes particulate contaminants from the diesel exhaust fluid before the fluid reaches the selective catalytic reduction (SCR) injector. A clogged or degraded filter can restrict fluid flow, leading to reduced NOx conversion efficiency and potential diagnostic trouble codes. The manufacturer, AGCO, produces this component to match the housing seal geometry and bypass-valve cracking pressure of the original assembly, ensuring the SCR system maintains its calibrated dosing rate. When replacing the filter, inspect the housing sealing surface and tighten the cap to the specified torque.
