The AF-DU axial smoke extraction fans are designed to efficiently remove smoke and gases generated during a fire while simultaneously extracting heat from the serviced room or building. This ensures safe conditions for firefighting operations, as well as the protection and evacuation of people and equipment.

The AF-DU fans feature: Durable casing; High-performance impeller; Reliable electric motor; Protective enclosure for safety and longevity.

Performance Features:

• These high-pressure, high-flow fans generate a significant portion of dynamic pressure in the total pressure output.

• To minimize pressure losses in the network sections adjacent to the fan outlet — especially when no ductwork is installed — it is recommended to install an outlet channel with a guide apparatus (configurations 02 and 04).

• Using a guide apparatus reduces the fan’s dynamic pressure by nearly 2.5 times, improving efficiency and airflow control.

Advantages:

• Efficient removal of smoke and hot gases;

• Reliable operation under extreme conditions;

• Enhanced safety during fire events;

• Easy installation and maintenance.
