20701801 VOLVO FM 420 Twin Cylinder, Air Compressor

The heavy-duty Twin Cylinder, Air Compressor is a critical component designed to ensure consistent air pressure within the pneumatic braking system. This high-strength component is engineered to handle the rigorous demands of heavy commercial vehicle engine environments, providing reliable service through its advanced water-cooling architecture and precise internal tolerances.

20701801 is the OE-equivalent of the VOLVO 20701801 Twin Cylinder, Air Compressor used in the VOLVO FM 420. This component ensures seamless integration with the vehicle's air brake system, maintaining optimal pressure for safe operation. The precision-engineered cylinder bore and stroke are specifically calibrated to meet the technical requirements of high-output diesel engines.

Workshop technicians should note that this unit features a water-cooled valve plate and is designed for water-cooled systems. Installation requires careful attention to the M16x1,5 water inlet/outlet ports and the M26x1,5 air outlet port to prevent leaks. Regular maintenance of the unloader port and checking the ESS feature functionality is recommended to ensure long-term durability in heavy commercial vehicle service environments.

Detailed technical specifications include a 704cm³ swept volume and a Ø35 air inlet port. This part is essential for maintaining the pneumatic integrity of the braking system in heavy-duty applications, ensuring that air delivery remains stable even under high-load conditions.
