Product description
The urea filter module from MANN+HUMMEL protects SCR systems by removing dirt particles from the AdBlue urea solution. It is designed for integration on either the suction or pressure side of the SCR system and allows the incorporation of additional functions in a compact module. The design targets heavy-duty applications such as construction and agricultural machinery where continuous performance is required.

Product benefits

• Protects SCR components from particle-induced wear
• Reduces machine downtime and increases operational availability
• Extends service intervals
• Fast, easy and clean maintenance
• Enables suction-side application via patented degassing membrane
• Provides freeze stability through patented compensation elements and optional heating (electrical or hydraulic)
• Flexible integration into existing SCR systems

Technical features
Volume flow range: Up to 120 l/h
Operating temperature: -5 °C to +85 °C
