457 130 48 15 MERCEDES BENZ CONECTO O345 OM447 Air Compressor

The heavy-duty twin cylinder air compressor provides essential pneumatic pressure for heavy commercial vehicle braking systems. Designed to meet rigorous industrial standards, this component features a water-cooled valve plate and integrated ESS functionality to ensure stable operation under high-load conditions. The dual-cylinder configuration and optimized swept volume make it a critical part for maintaining consistent system pressure.

457 130 48 15 is the OE equivalent of the MERCEDES BENZ 457 130 48 15 twin cylinder air compressor used in the MERCEDES BENZ CONECTO O345 OM447 engine systems. This unit is specifically engineered to match the exact technical requirements of the original equipment, ensuring seamless integration with the vehicle's pneumatic architecture.

Workshop technicians should note the specific port dimensions: the Air Inlet and Air Outlet ports utilize M26x1,5 threading, while the Air Unloader Port is M12x1,5. The unit is water-cooled (W) with M16x1,5 inlet and outlet ports for the cooling circuit. Proper installation and regular inspection of the water-cooling connections are essential to maintain optimal thermal management during long-haul operations.

Regular maintenance of the air compressor assembly helps prevent system failures in heavy-duty transit applications. By ensuring the water-cooled valve plate remains free of obstructions, technicians can extend the service life of the component and ensure reliable air delivery for the entire braking system.
