Tunnel Jet Fans

Jet fans are essential for two primary tunnel applications:

• Daily Ventilation – Ensuring consistent airflow and air quality.
• Emergency Ventilation – Assisting in smoke extraction during fires and facilitating the safe evacuation of individuals.

In emergency situations, our jet fans efficiently remove smoke from the fire source, providing a critical window for evacuation. These fans are equipped with components and motors capable of operating at high temperatures, ensuring reliability under the most challenging conditions. Both our fans and motors comply with EN-12101-3 standards and hold F300 and F400 certifications. (See: Documents)

Smoke Dampers for Smoke Control Systems

Smoke dampers are specifically designed to restrict the flow of smoke within a building, playing a critical role in engineered smoke control systems. These dampers automatically close using actuators during fire incidents, controlling the movement of smoke when the HVAC system is operational.

Applications of Smoke Dampers

Smoke dampers serve two primary functions:

• Passive Smoke Control Systems:
  The dampers close to prevent the circulation of air and smoke through ducts, effectively isolating affected areas.

• Engineered Smoke Control Systems:
  Designed to work alongside walls and floors as smoke barriers, these systems use the building’s HVAC system and/or dedicated fans to create pressure differentials, controlling the spread of smoke throughout the structure.

The ADS-2020-1 Smoke Dampers are specifically designed for use in dynamic HVAC systems to prevent the spread of smoke during life safety situations.

Aironn Axial Type Smoke Exhaust Fans

The Aironn Axial Type Smoke Exhaust Fan series is certified for 300°C for 2 hours and 400°C for 2 hours in compliance with EN 12101-3. With adjustable blade angles across diameters ranging from 400 mm to 1600 mm, the series offers a wide performance range, delivering precise flow rates tailored to specific requirements. The performance of these fans has been rigorously tested in accordance with the AMCA 210-07 standard.

Fan Body

The fan bodies are constructed from high-quality, corrosion-resistant, hot-dip galvanized sheet metal. The flanges are self-flanged, formed by bending the body. Both short and long body models are available, ensuring suitability for vertical or horizontal installation. An optional body inspection hatch is also offered.

Fan Blades
