¿QUÉ ESTÁS BUSCANDO?
The High-Volume Positive/Negative Pressure Smoke Exhaust Fire Truck is a specialized emergency response vehicle designed for rapid smoke extraction, ventilation, and air circulation during major fire incidents. It is engineered to support firefighters in tunnels, underground facilities, large industrial buildings, high-rise structures, warehouses, and disaster areas where smoke accumulation severely affects visibility, evacuation, and rescue operations.
Built on the powerful Mercedes-Benz Arocs 3358 6×4 chassis, this vehicle integrates an ultra-high-capacity smoke exhaust system, independent power generation, positive and negative pressure ventilation functions, and intelligent control technology. With a maximum airflow of 800,000 m³/h, it provides efficient smoke removal and improves safety for rescue teams operating in hazardous environments.
The vehicle is equipped with a high-power smoke exhaust fan system designed for large-scale fire environments.
The system rapidly removes smoke, toxic gases, and heat, improving visibility and supporting safer firefighting operations.
The vehicle supports both positive and negative pressure smoke control modes to adapt to different rescue scenarios.
Applications:
Applications:
This dual-function design allows emergency teams to select the most effective ventilation method according to site conditions.
To ensure continuous operation, the smoke exhaust system is powered by an independent generator.
The independent power system allows the vehicle to operate effectively in locations where external electricity supply is unavailable.
The vehicle includes an integrated water tank system to provide additional firefighting support and equipment protection.
This improves durability and supports extended emergency operations.
The MX smoke exhaust vehicle uses an advanced electronic control architecture.
Control Features:
Operators can monitor and adjust ventilation functions efficiently during complex rescue missions.
The vehicle includes dedicated duct equipment for flexible ventilation deployment.
Included:
The modular duct system enables rapid setup in tunnels, buildings, and confined spaces.
