Plenum Boxes

Floor louver adapter

AIO Wall-Mounted Pro Units can be used with several adapters, which enable a very high level of installation flexibility. The following pages summarize the adapters available with the wall-mounted unit. These adapters are available for order by Thermaduct.

Floor louver adapter

The floor louver adapter enables AIO Wall Mounted Pro to vent through a sleek linear louver below the unit. The adapter is designed to fit inside a standard wall assembly or aluminum profile, so only the AIO is visible inside the room. On the exterior, all that is visible is a slim linear louver. The curved base assists the airflow while allowing any water penetrating the louvers to drip directly outside. This adapter is fully customizable and available through our certified part supplier, Thermaduct.

Window assembly adapter

The window louver assembly adapter enables AIO Wall Mounted Pro units to vent through a window/louver assembly (similar to an assembly used with PTACs), with a slim louver. The plenum box is designed to fit inside a standard shear wall or aluminum profile, so all that is visible is the AIO unit. This adapter works with wood and steel stud construction and is ideal for glass curtain wall construction. This adapter is fully customizable and available through our certified part supplier, Thermaduct.

Windowsill adapter

The windowsill adapter enables AIO Wall Mounted Pro units to be mounted on the wall below the window without any construction. It is ideal for retrofit installations where drilling vent holes in the facade isn’t feasible. Once installed, the window is still fully operable. Deeper side panels are available to conceal the adapter so that the assembly looks sleek and finished. A new windowsill of any material may be placed on top of the plenum box to complete the integration. This adapter is fully customizable and available through our certified part supplier, Thermaduct.

High window adapter

The high window adapter enables the installation of Wall Mounted Pro units on the wall above the window without any construction. It is ideal for retrofit installations where it is not desirable to have AIO mounted below the window and where making an opening in the facade isn’t feasible. Once installed, the window is still fully operable. The plenum box’s base is curved, assisting airflow while allowing any water penetrating the louvers to drip outside. This adapter is fully customizable and available through our certified part supplier, Thermaduct.

Sidewall adapter

The sidewall adapter is ideal for applications where it’s not feasible or practical to mount AIO wall units on an exterior wall, venting directly out. With the sidewall adapter, the units can be mounted on a wall perpendicular to the outer wall in low-wall or high-wall positions using the sidewall adapter. The sidewall adapter is recessed into the wall. The sidewall adapter is available for right-side or left-side applications. This adapter is fully customizable and available through our certified part supplier, Thermaduct.

Duo sidewall adapter

The duo sidewall adapter is perfect for applications where it’s desirable to have two AIO Wall Mounted units back-to-back on a shared wall. Mounting inside the wall enables an AIO Wall Mounted pro unit to be installed on each side, in a high-wall or low-wall configuration. This adapter is fully customizable and available through our certified part supplier, Thermaduct.

PTAC adapter

The PTAC adapter enables the Wall Mounted Pro unit to be mounted to an existing PTAC sleeve. The plate covers the entire PTAC sleeve opening (and half-inch on each side to cover any wall seams), sealing the PTAC opening entirely so there are no air leaks. No construction is required. This adapter is fully customizable and available through our certified part supplier, Thermaduct.
