Description

The high-capacity air compression system is essential for maintaining consistent pneumatic pressure in heavy-duty commercial vehicles. This twin-cylinder unit is engineered to meet the high air demand of complex systems, ensuring reliable performance during heavy-haul operations.

The 3400 020 001 is the OE equivalent of the high-strength component used in specialized heavy-duty engine configurations. This twin-cylinder air compressor features a cylinder bore of Ø85.00 and a stroke of 60 mm, providing a swept volume of 680cm³. It is designed as a water-cooled unit with an M26x1,5 air outlet port and an M27x1,5 air inlet port to ensure optimal thermal management and stability under load.

For workshop technicians, this component offers precision fitment with its specific M16x1,5 water inlet and outlet ports. The inclusion of an ESS feature and a water-cooled valve plate ensures the unit remains operational even under extreme thermal stress. Regular inspection of the unloader port and connections is recommended to maintain peak system efficiency.

Selecting a twin-cylinder configuration is critical for vehicles operating with high air consumption, such as those pulling multi-trailers or operating specialized bodies. This ensures the compressor does not run constantly at full load, thereby extending the service life of the entire pneumatic system.

FAQ

What are the primary technical specifications of this unit?
This twin-cylinder unit features an Ø85.00 bore, a 60 mm stroke, and a 680cm³ swept volume. It operates as a water-cooled system with specific M27x1,5 and M26x1,5 ports.
When should a twin-cylinder compressor be used instead of a single-cylinder one?
Twin-cylinder compressors are ideal for heavy-haul, vocational vehicles, or multi-trailer setups where high air demand requires more than the ~13-18 CFM typically provided by single-cylinder units.
Does this air compressor feature water cooling?
Yes, this model is designed for water cooling (W) and includes dedicated water inlet and outlet ports (M16x1,5) to manage operating temperatures effectively.
What is the benefit of the ESS feature in this component?
The integrated ESS feature ensures enhanced system stability and control within the pneumatic circuit, making it suitable for demanding heavy commercial vehicle applications.
How can I ensure correct compatibility during installation?
Technicians should verify the port sizes (M27x1,5 inlet and M26x1,5 outlet) and the through-drive requirements to ensure a seamless fit with the existing engine and braking system.
