Description
Product Introduction
The 6.7kW water-driven fire exhaust ventilator is a specialized emergency ventilation system powered by water pressure, eliminating reliance on electricity. Designed for rapid smoke and heat removal, it enhances safety in fire-prone environments like tunnels, basements, and industrial facilities, ensuring efficient airflow under critical conditions.
Use
Ldeal for smoke control in fire-prone areas like tunnels, underground parking, subways, industrial plants, and confined spaces lacking electricity.

Product Function
- Delivers powerful airflow (up to 15,000 m³/h) to rapidly evacuate toxic smoke and heat during firefighting operations.
- Activates instantly via water pressure (0.3–1.2 MPa), eliminating reliance on external power sources in emergencies.
- Engineered with corrosion-resistant stainless steel and heat-insulated components to withstand temperatures up to 300°C.
- Integrates a pressure-relief valve to halt operation if water supply fails, preventing mechanical damage.
- Features a sealed bearing system and self-lubricating impeller, reducing downtime and maintenance costs.
Note：Mount the unit securely on a non-combustible surface near a water supply. Connect the water inlet (min. 2 bar pressure) and exhaust duct (≥250mm diameter). Test operation monthly; ensure no obstructions block airflow. Regularly inspect seals and impeller for damage.
