For sizable equipment booths, a substantial AMU is essential to meet air flow requirements efficiently. Thoughtful planning is crucial in selecting the appropriate placement for these larger AMUs. Typically, these units are installed outside the building—either horizontally on the building’s roof or vertically alongside it. The dimensions and weight of these units should be carefully considered, aligning with the overall size of the booth; certain AMUs might surpass 20 feet in length or even more.
