Description
The Daikin 0270L01338 Concentric Duct Adaptor Kit for 18" Diameter Duct works with any 3-6 ton Daikin packaged air conditioner unit. Concentric duct kits are used to help connect rooftop-mounted units with concentric diffusers (included), thus helping to eliminate the need for traditional duct-work by providing a single location for air to enter and leave the building.
