I. Requirements Analysis

In modern firefighting, tunnel construction, underground parking garages, mining operations, and large-scale buildings—where environments are enclosed or semi-enclosed—rapid and effective smoke and air extraction becomes critical for ensuring personnel safety and minimizing property damage when fires occur or harmful gases accumulate. Traditional electrically powered smoke extraction equipment may become inoperable during power outages in certain environments. Water-driven smoke extraction units, however, overcome this challenge through their unique power source—water. Utilizing high-pressure water flow as their energy source, these units require no external power supply and can rapidly activate during emergencies to achieve efficient smoke removal, thereby securing critical time for rescue and evacuation operations.

II. Product Features

1. Independent Power Source: Utilizes high-pressure water flow as its power source, eliminating reliance on external power supply. This ensures continued operation during emergencies such as power outages.

2. High-Efficiency Smoke Extraction: Featuring optimized airflow channels and high-efficiency impellers, it achieves smoke extraction rates of 20,000 to 27,000 m³/h, rapidly eliminating smoke and harmful gases.

3. Energy Efficiency and Environmental Protection: Utilizing water resources as a power source with zero pollution emissions, aligning with green and eco-friendly principles.

4. Compact Design: With dimensions of just 650 × 650 × 760 mm, it facilitates transportation and installation while adapting to various complex environments.

5. Safe and Reliable: Manufactured from high-strength materials and rigorously tested to ensure stable operation under high-pressure water flow. Equipped with safety protection devices to prevent accidents.

6. Easy Maintenance: The rational structural design facilitates disassembly and cleaning, reducing maintenance costs.

III. Application Scenarios

1. Firefighting Applications: Used for rapid smoke extraction at fire scenes, providing rescue personnel with clear visibility and a safe working environment.

2. Tunnel Construction: During tunnel excavation, harmful gases and dust are removed to safeguard the health of construction personnel.

3. Underground Parking Garages: Prevent vehicle spontaneous combustion and other emergencies by promptly removing smoke to ensure safe evacuation of personnel.

4. Mine Ventilation: Conducting ventilation operations within mine shafts to reduce concentrations of harmful gases and enhance workplace safety.

5. Large-scale buildings: Such as shopping malls, exhibition halls, etc., where emergency smoke exhaust systems are installed to address sudden incidents.
