Product introduction
A smoke and heat exhaust fan is a specialized ventilation device designed to remove smoke and heat during emergencies such as fires. Its main components include a high-efficiency motor, large-diameter impeller, high-temperature resistant casing, and fire damper. The fan works by rotating the impeller to create negative pressure, drawing smoke and hot air into the inlet and expelling it through the exhaust duct.
These fans can typically operate continuously for 60 minutes at temperatures up to 300°C. With an exhaust capacity ranging from 5,000 to 50,000 cubic meters per hour, they efficiently remove large volumes of smoke early in a fire event, reducing indoor smoke concentration and providing crucial time for safe evacuation and fire rescue operations.

High Temperature Resistance
The housing, blades, and motor of the smoke and heat exhaust fan are made from high-temperature, fire-resistant materials such as galvanized steel and specialized fireproof coatings. These fans can operate continuously for 60 to 120 minutes at temperatures of 300°C to 400°C. This robust heat resistance ensures the fan functions reliably during the early stages of a fire, quickly expelling heat and smoke from the building while preventing damage caused by excessive temperatures.
Large Air Volume Discharge Capacity
Equipped with a large-diameter impeller and an optimized, high-efficiency air duct design, the smoke and heat exhaust fan delivers powerful airflow. The large impeller boosts air-driving force to increase exhaust volume, while the streamlined duct reduces airflow resistance, enhancing overall efficiency. This design allows the fan to exhaust between 5,000 and 50,000 cubic meters of smoke and toxic gases per hour. Such capacity is vital in large public spaces like shopping malls, stations, and underground parking lots, where it helps maintain clear evacuation routes, improve escape times, and ensure safe personnel evacuation.
Intelligent Automatic Start
The smoke and heat exhaust fan integrates with automatic fire alarm systems for intelligent, automatic activation. Upon detection of smoke or high temperature by sensors, the fan immediately starts to remove smoke and reduce heat. This rapid, automatic response eliminates delays from manual intervention, minimizing smoke and toxic gas spread. It is especially beneficial in unstaffed locations such as basements and warehouses, improving emergency response efficiency.
Low Noise Design
Noise reduction in the smoke and heat exhaust fan is achieved through the use of multi-layer silencers and streamlined impeller blades. The silencers absorb and dampen airflow noise, while the aerodynamic blades minimize friction noise caused by air movement. These features keep the fan's operating noise below 70 decibels, ensuring minimal disturbance in quiet environments like hospitals and libraries during daily operation and maintaining clear communication during emergencies.
