Air intakes are openings or ducts that allow air to enter a system, such as an engine or a building. In vehicles, air intakes are crucial for supplying the engine with the oxygen it needs for combustion, which helps the engine run efficiently. They can be designed in various shapes and sizes to optimize airflow and performance. In buildings, air intakes are part of heating, ventilation, and air conditioning (HVAC) systems. They help bring fresh air inside while removing stale air, ensuring a comfortable and healthy indoor environment. Properly designed air intakes can improve air quality and energy efficiency.
