Jet fan

Jet fans are modern impulse ventilation solutions designed to move and direct air efficiently across underground car parks, tunnels, garages and other large enclosed areas. By producing a high-velocity air stream, a jet fan induces movement in the surrounding air mass and helps direct polluted air toward the main extraction points of the ventilation system. This approach is particularly useful in projects where large conventional duct networks would occupy valuable ceiling space or complicate the installation.

In underground car parks, effective air movement is essential for controlling pollutants generated by vehicles. A properly designed jet fan system helps minimise stagnant air zones and creates controlled airflow paths toward extract shafts and main exhaust fans. Jet fans can operate as part of an integrated ventilation solution together with extraction fans, fresh-air openings, sensors and automatic control systems.

For fire-safety applications, appropriately specified and certified jet fan models can also form part of a smoke-control strategy. Their role is to assist in directing smoke toward designated extraction areas according to the engineering design of the building. The required number of fans, their positioning, airflow direction and thrust performance must therefore be selected according to the geometry and operating conditions of each project.

One of the main advantages of jet fan ventilation is its compact installation. By reducing the need for extensive ductwork, the system can preserve more usable ceiling space and provide greater flexibility in modern car park design. Jet fans are therefore widely suited to residential developments, shopping centres, hotels, office buildings and other commercial facilities.
