Why Choose Vertical Stack

AIO Vertical Stack is the ideal multi-room solution when a ceiling-mounted unit is not desired or feasible. The compact 12-inch by 25-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 unit 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 – which can be field modified to left or right. The Vertical Stack unit is available with or without the integrated ERV and can be vented directly outside or through ductwork.
