20701801 SP1 Mercedes-Benz Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor is a critical component for maintaining pneumatic pressure within the braking system of heavy commercial vehicles. Designed to operate via direct drive, this unit ensures a consistent supply of compressed air to the air processing unit and tanks, which is essential for reliable braking performance.

Compatibility and vehicle fitment

This specific model is designed for compatibility with Mercedes-Benz vehicles. It features a water-cooled design to manage operating temperatures during heavy-duty service, ensuring long-term stability. The unit includes a water-cooled valve plate and is built with high-strength components to withstand rigorous industrial conditions.

Installation and technical specifications

For proper installation, technicians should verify the M26x1.5 air inlet port and M14x1.5 water ports to ensure a precise fit. Given the 12.3 kg weight and specific Ø85.00 mm bore, it is vital to match all connection points during replacement to prevent pressure leaks or cooling inefficiencies in the system.

Maintenance and system checks

Regular inspection of the water inlet and outlet connections is recommended to prevent overheating. Maintaining the integrity of the single cylinder housing and valve plate helps ensure optimal air output for the vehicle's pneumatic systems.
