What Is a Jet Fan in Car Park Ventilation? How to Select the Right Jet Fan?
A jet fan creates a high-velocity air jet that entrains and moves a much larger volume of surrounding air. In enclosed car parks, it is used to direct airflow toward the exhaust points.

Its two main functions in a car park
During normal operation, it helps reduce the accumulation of vehicle-related pollutants. In a fire scenario, it becomes an active part of the system by helping move smoke in the designed exhaust direction.
Axial vs radial jet fans
Axial jet fans generate a strong, linear airflow. Radial jet fans can offer advantages where ceiling height is limited or where the layout requires a different discharge pattern. Selection should be based on car park geometry and the airflow strategy.
What data is needed for selection?
Car park area and floor-to-ceiling height, fresh-air and exhaust points, required thrust, fan layout, fire scenario and temperature resistance should be evaluated together.
How does the Vitlo solution fit the project?
Vitlo AXJ axial jet fans and RXJ radial jet fans can be considered for car park ventilation and smoke-control projects. The correct model should be selected according to the whole system, not only the fan airflow value.
