Vertical stack XL
AIO Vertical Stack XL is the higher capacity version of the Vertical Stack and is designed to fit in the same space as a VTAC. The compact 23-inch by 24-inch footprint uses minimal floor space. This unit is perfect anywhere direct venting or ducting is required with up to 0.6” WC external static pressure. Use any style grilles and louvers for maximum design flexibility. A unique feature of the AIO Vertical Stack XL is that it can be installed on a corridor wall, enabling it to be fully serviced without entering the apartment or hotel room. A bathroom exhaust can connect to the dedicated stale air exhaust on either the right or left side. The Vertical Stack XL unit is available with or without the integrated ERV and can be vented directly outside or through ductwork. Watch how it is installed by scanning or clicking the QR code.
