Understanding AHU

What Is an Air Handling Unit (AHU)?

An Air Handling Unit is like a big air cleaner for buildings. Additionally, it moves air around your building. Moreover, it can heat, cool, and clean the air. Therefore, it's an important part of any building's air system.

Think of it this way: your lungs breathe air for your body. Similarly, an AHU breathes air for your building. Furthermore, it makes sure everyone inside has clean, comfortable air.
