Mercedes Benz 800L Air Supply Unit

BRIEF

The Mercedes-Benz 800L air supply unit produced by CSCTRUCK Fire Rescue Truck is a high-performance mobile breathing air generation and support system designed for demanding emergency rescue, firefighting support, industrial safety operations, and confined-space interventions. Built on the reliable Mercedes-Benz Arocs 1836E6 chassis, this unit combines robust mobility, advanced air purification technology, and a stable onboard power supply to ensure continuous clean breathing air delivery in critical environments.

Powered by a 266 kW diesel engine (360 HP), the system features an automatic transmission and a 4×2 drive configuration, delivering smooth and efficient operation on various road conditions. Euro 6 emission compliance, it meets modern environmental standards while maintaining strong performance. The vehicle measures 8,580 × 2,520 × 3,970 mm and has a wheelbase of 4,500 mm, offering a balanced structure between maneuverability and equipment capacity. It supports a driver and 1 passenger, emphasizing its specialized operational role.

At the core of the system is a powerful air generation and purification package. The air compressor delivers an exhaust volume of 120 m³/h, while the air cooler achieves a flow rate of 2,850 L/min. The integrated breathing air purification and filtration system provides a filtration volume of up to 3,600 m³, ensuring high-quality breathable air suitable for emergency use. The rated pressure reaches up to 350 bar, enabling high-pressure air storage and distribution.

The Mercedes-Benz 800L air supply unit is also equipped with a 128 kW onboard generator supplying 380V/220V electrical output, supporting auxiliary systems such as lighting and air processing equipment. The lighting system has a power output of 4 kW and a maximum lifting height of 7.7 meters, providing strong illumination for night operations or disaster scenes.

For air storage, the system includes a spare gas cylinder rack capable of holding 6.8/9L × 75 cylinders and a 50L × 16 cylinder set, ensuring large-scale air supply readiness. Overall, the Mercedes-Benz 800L air supply unit is a highly reliable and efficient solution for continuous breathing air support in extreme operational conditions.
