The blower fan is a powerful electric machine that provides ventilation or air circulation for appliances or buildings that require air flow. The blower fan can be small as a Matchbook size device in a notebook used to keep the processor in the cold or as large as a truck installed in a large factory to provide ventilation. Technically, the blower fan provides a pressure of 1,136-2,066 millimeters of a water meter (MMWG)-more than a simple fan and less than a strong air compressor. The blower fan has three main components: a fan that moves the air through the blades; powerful motor with lubricated moving parts that spin the fan blades; and the power supply that provides the engine's electricity. The metal or plastic case contains assembled parts.
