Detailed Description

This Universal Air desiccant insert is built for vehicles that use a serviceable receiver drier desiccant element rather than a complete drier assembly. In Mercedes-Benz HVAC systems, the desiccant helps remove moisture from the refrigerant circuit, which is important for stable cooling performance and for protecting internal A/C components from moisture-related wear. RD10909C is listed for select Mercedes-Benz SLK300, SLK55 AMG, SLK350, SLK280, C230, C240, C320, C55 AMG, CLK320, CLK500, CLK55 AMG, C32 AMG, and CLK430 applications.

This part cross-references OE-style replacement applications for the same Mercedes-Benz receiver drier service needs. RD10909C is a practical choice when servicing the A/C accumulator / receiver drier on the listed vehicles.

What It Helps Address

• Moisture contamination in the A/C refrigerant circuit
• Reduced cooling efficiency caused by a saturated desiccant element
• Service needs on Mercedes-Benz receiver drier systems
• HVAC performance issues tied to aging desiccant material
• Maintenance on vehicles with a replaceable desiccant insert
