Daikin 20 Ton Concentric Duct Kit - CDK240

The Daikin CDK240 Concentric Duct Kit works with any 20 ton Daikin packaged air conditioner unit. Concentric duct kits are used to help connect rooftop-mounted units with concentric diffusers, thus helping to eliminate the need for traditional duct-work by providing a single location for air to enter and leave the building.
