A fan assembly comprises a fan and a movable fan support. The fan has a motor and a fan blade drivable by the motor to move air in an airflow direction through an opening. The movable fan support is configured to movably support at least the fan. The fan support is mountable adjacent the opening on a first side and comprises extension members extendable from an operating position on the first side of the opening to an access position on a second side of the opening opposite the first side. In the access position, the extension members extend through the opening from the first side to the second side to support the motor and fan blade on the second of the opening for access.
