Carbon monoxide buildup in enclosed multi-level parking garages used to be solved by massive, ugly duct networks ruining the clearance height of the ceiling. Today, we achieve vastly superior results utilizing the Jet Fan Ventilation System.
How Thrust Replaces Ducts
Jet fans operate completely without physical ducts. Instead, they use raw thrust force (typically measured in Newtons). By placing these fans in a calculated, staggered array across the ceiling, they effectively create an invisible "river" of moving air.
They push the toxic exhaust fumes towards the massive main exhaust shafts, which then violently draw the polluted air outside.
Why CFD Analysis is Non-Negotiable
You cannot just hang jet fans arbitrarily. At Rota Yapı, before we ever order a fan, we run a Computational Fluid Dynamics (CFD) simulation. We model the entire parking garage in 3D. We simulate a vehicle fire at the absolute worst possible corner.
The software shows us exactly how the lethal heat and black smoke will behave. We then position the jet fans digitally to ensure they create an aerodynamic "wall", holding the smoke back and keeping the pedestrian exit stairs mathematically clear of toxins for a calculated amount of time, giving civilians the precious minutes they need to safely evacuate.
Furthermore, these systems must be F300 or F400 rated—meaning they are certified to withstand and operate inside temperatures of up to 400°C for straight two hours without melting down.
