An air circulating device for suspension from a roof or ceiling structure and including a duct through which upper room air may be directed for discharge into lower temperature air immediately above the room floor. A support structure houses a fan and motor assembly and a collar to receive the duct upper end. The inflatable duct is of a yieldable nature and terminates in spaced relationship to the floor. Provision is made for mixing lower room air with the duct airflow and for the imparting of a rotational direction to the duct discharged airflow.
