Hi...could you tell me the difference between Fan and Ventilator? Thanks.
A fan is a device with three metal blades that turns around and around, and pushes air in one direction. A ventilator is any machine that supplies air. A fan may be a part of a ventilator, and there may exist some ventilators that do not use fans, such as a window.
