Extraordinarily Flexible Ducting

Model V’s powerful backward centrifugal ECM fan facilitates efficient condenser air movement through ductwork, enabling flexible placement within a room or apartment. Unlike traditional VTACs, it doesn’t require an outside wall. The design allows air supply from the top or both sides, with flexible condenser intake options (left, right, or rear). Flexible ducting choices with 0.7 in. W.C. make Model V versatile for installation without restrictions in any dwelling area.

No Access Required

The versatile design of AIO makes the system extremely reliable and inexpensive to maintain. If a repair is needed, a single unit can be taken off-line without affecting the entire system. It’s possible to install AIO Vertical stack on the corridor wall of each apartment/hotel room so that all maintenance can be achieved from a common area – at any time, which means no maintenance personnel needs to enter the unit.

Advanced Airflow System

AIO Wall Mounted Pro is extraordinarily flexible in how it can externally vent. A host of adapters are available that enable AIO Wall Mounted Pro to be installed in many scenarios, including on glass curtain walls with linear louvers, integrated window, and louver assemblies, or even with no construction using a windowsill adapter.
