INNOVA 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 58 cm by 61 cm footprint uses minimal floor space. This unit is perfect anywhere direct venting or ducting is required with up to 150 Pa external static pressure. Use any style grilles and louvers for maximum design flexibility.
A unique feature of the INNOVA 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.

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 175 Pa ESP make Model V versatile for installation without restrictions in any dwelling area.
