Airflow Management

Efficient management of airflow in and around high speed transportation equipment is key to optimizing fuel efficiency and operating costs. A recirculation shield, also referenced as baffle assemblies or under hood air flow management, is intended to help control the flow of air in engine compartment areas of various transportation vehicles, most commonly heavy duty or class 8 trucks. Transportation vehicle designers must also combat the impact of air drag as it moves down or around a vehicle. Critical designs to manage air behind a class 8 truck cab, like a flex extender, or under a freight trailer, like an aero skirt, help to decrease drag as well. These highly engineered air shields, flex extenders and aero skirts help OEMs meet efficiency targets through effective aerodynamic design, radiator airflow management and air drag reduction. These complex aerodynamic components redirect air around the inefficient designs, like a radiator assembly, to other areas of the truck more efficient at managing air and reducing drag.
