Flexible and Convenient Heating and Cooling with Stealth Designer Series Concealed Ducted Units

The Stealth Designer Series Concealed Ducted Units provide flexible heating and cooling options by allowing the air handler to be concealed above ceilings, beneath floors, above closets, or in hallways. This allows for supply air to be delivered directly into rooms through a grate, or through a field-fabricated duct board plenum and flex ducting.

These air handlers come equipped with a factory-installed condensate drain pump to move water to a safe discharge location, and a wall-mounted thermostat is included for convenient temperature control.

It's important to note that this air handler must be connected to an outdoor condenser in order to function.
