The JF-DU/DUV jet fan  is designed for forced ventilation and efficient smoke extraction in case of fire, ensuring safety in enclosed and underground parking lots or garage facilities.
During a fire, toxic gases such as nitrogen oxides, carbon monoxide, and soot are evenly distributed throughout the parking area — therefore, efficient smoke removal must occur across the entire space.

Jet fans are installed at intervals under the ceiling of the parking area, ensuring air movement along the entire length without the need for air ducts — the entire cross-section of the parking becomes an effective ventilation channel.

This system allows for:

• reliable smoke extraction during and after a fire;

• safe evacuation routes for people in emergency situations;

• unobstructed operation of other systems (sprinklers, power lines, surveillance cameras);

• energy efficiency, since the system operates only when necessary and has no pressure loss through ducts;

• simplified installation and flexible configuration of the ventilation layout;

• low equipment and maintenance costs.

The JF-DU/DUV jet fan is an innovative and cost-effective solution for modern smoke ventilation systems, providing both safety and operational efficiency in large enclosed spaces.
