The aircraft pre-ventilation system has a ventilation unit mounted for movement along the ground. A primary and a return duct carry air between the ventilator and the aircraft door opening. The ducts are connected to a fitting which is designed to fit into and seal different size door openings for different aircraft. The fitting has a central rigid member, and a flexible bladder is attached to and surrounds the outside of the central member. The fitting is supporting by an adjustable arm for positioning the fitting in the door opening. When the fitting is properly positioned, the bladder expands to secure and seal the fitting to the aircraft door opening. The support arm that holds the fitting is hollow and carries pressurized air from the ventilator to a hose near the fitting that carries the air into the bladder.
