The Quest Return Air Duct Collar allows a limited amount of ductwork to be attached to the intake on Quest Dual dehumidifiers. This allows the dehumidifier to be located outside of the indoor garden. This collar attaches where the moist air is drawn into the Quest unit. Be sure to also purchase the supply air attachment collar to attach ductwork to the air outlet and send dry air back into the garden. 12 in diameter flange.
