Urea filters

SCR systems can be damaged by dirt particles in the urea. Urea filter from MANN+HUMMEL efficiently protect SCR systems from wear, thus extending their service life. The filters can be integrated into the SCR system on the suction or pressure side and reliably filter the dirt particles from the urea solution "AdBlue". Numerous functions can be easily integrated into the module.
