Advantages of a Centrifugal Type Jet Fan
Superior Throw
The centrifugal jet design produces a high-velocity, focused air stream, ideal for directing air and smoke across large, open areas like car parks.
Low Profile Design
Our centrifugal jet fans have a significantly lower height than axial fans, preserving valuable clearance height in confined spaces.
Certified Safety
Rigorously tested and certified to EN 12101-3 standards for high-temperature operation (F300/F400), ensuring reliability during a fire.
Primary Applications for Centrifugal Jet Fans
Underground Car Park Ventilation
The primary application for centrifugal jet fans. They create air movement to exhaust CO fumes during normal operation and clear smoke during a fire, eliminating the need for costly ductwork.
Tunnel Ventilation
In road and rail tunnels, these fans provide longitudinal ventilation for pollution control and emergency smoke extraction, ensuring user safety. The high thrust of a centrifugal jet is critical here.

Frequently Asked Questions
The primary difference is airflow direction and profile. An axial fan moves air parallel to its axis, creating a wider cone of air. A centrifugal jet fan draws air in axially and discharges it radially (at 90 degrees) into a housing that directs it out. This creates a more focused, higher-velocity jet stream. For car parks, the centrifugal type jet fan is often preferred for its low profile and ability to 'throw' air further, overcoming obstacles.
The number and placement of centrifugal jet fans are determined through a detailed Computational Fluid Dynamics (CFD) analysis. Our engineers model the car park's geometry, considering factors like ramps, columns, and ceiling height. The CFD simulation calculates the required thrust to achieve the desired air changes per hour (for CO ventilation) and to effectively move smoke towards the main extract points in a fire scenario. We offer CFD analysis as a service to ensure optimal system design.
