The Return Duct Kit allows a limited amount of duct work to be attached to the intake on Quest Dual 110 Dehumidifier. This allows the dehumidifier to be located outside of the indoor garden. Be sure to also purchase the Supply Duct Kit (part #310787) to attach duct work to the air outlet and send dry air back into the garden. This 10 inch flange fits the Quest Dual 110 Overhead Dehumidifier only.
