21098900 VOLVO Single Cylinder, Air Compressor

The single cylinder air compressor is a critical component within the pneumatic system of heavy commercial vehicles, responsible for maintaining consistent air pressure for braking and auxiliary functions. Engineered with high-strength components, this unit provides the necessary compression stability required for demanding driving conditions and long-haul transport operations.

This specific model is the OE-equivalent of the VOLVO 21098900 single cylinder air compressor used in VOLVO heavy-duty vehicles. It features a precision-engineered Ø80.00 cylinder bore and a 45mm stroke to deliver a swept volume of 225cm³. The assembly is designed with water-cooling capabilities to ensure thermal stability during continuous operation, making it a reliable choice for maintaining fleet uptime.

Workshop technicians should note that this unit utilizes an M26x1,5 air inlet port and an M22x1,5 air outlet port. The water-cooled valve plate and integrated water ports (M16x1,5) allow for efficient heat dissipation. When performing installation or maintenance on the air brake system, ensure all connections are secure to maintain the integrity of the pneumatic circuit and prevent pressure drops in the vehicle's braking system.
