This product is a dedicated air suspension compressor pump for Mercedes-Benz W212 chassis vehicles, with OEM number 2123200104, designed to replace aged, leaking, or underperforming original air suspension compressor assemblies. The pump features an oil-free lubricated piston design combined with high-purity copper motor windings, ensuring reliable continuous operation without overheating. An integrated large-capacity dryer effectively removes moisture from compressed air, preventing internal corrosion of air springs and valve blocks. Key components include reinforced piston rings and low-temperature resistant seals, delivering fast pressure build-up – reaching standard ride height from the lowest level within 28 seconds. Every unit undergoes dynamic pressure testing, air tightness inspection, and durability simulation before shipment, meeting OE quality standards. Compatible models include Mercedes-Benz E-Class sedans (W212) produced between 2009 and 2016, covering E350, E400, E500, E550, and the E63 AMG (non-AMG specific high-pressure version – please verify part numbers). Additionally, some same-platform C207 coupe and A207 convertible models equipped with air suspension are also compatible. Year coverage: 2009–2016 models, direct fit to original mounting points and line connections with no modification required.

• Color-changing silica gel in dryer – warns when saturated. Protects air springs from moisture damage.
• Built-in thermal protector – auto-pauses if overheated, resumes after cooling. Extends service life.
• Imported PEEK piston rings – wear-resistant & self-lubricating. Normal start at -30°C extreme cold.
• Waterproof breathable membrane at intake – blocks salty slush. Ideal for harsh winter regions.
