20846000 SP1 Twin Cylinder Compressor for Volvo FM11

This twin cylinder compressor is a critical component for the pneumatic air brake system of heavy commercial vehicles. Designed to provide consistent air pressure, it operates within the engine's cooling circuit to manage thermal loads effectively. The unit is constructed with heavy-duty grade materials to ensure long-term durability under high-pressure conditions.

This specific model is designed for Volvo FM11 trucks equipped with the D11A engine. It features a water-cooled design with a water-cooled valve plate and an ESS feature for optimized performance. The technical configuration includes an 85.00 mm cylinder bore, a 56 mm stroke, and a swept volume of 636cm³, ensuring precise air delivery for demanding fleet operations.

Technicians should verify the mounting flange and drive gear type during installation to ensure perfect alignment with the engine's timing gear. It is essential to check that the M26x1,5 air outlet port and M16x1,5 water inlet/outlet ports match the existing vehicle connections. Regular inspection of the water cooling lines and air inlet ports is recommended to prevent system pressure drops.

Always consult your authorized distributor to ensure this unit meets the exact specifications required for your specific engine variant.
