DC Fans are electric fans powered by direct current (DC) that are used for cooling within electrical devices and equipment. They are used to draw in fresh air and blow hot air away from equipment such as computers, air conditioners, amplifiers, and other electronic devices that generate heat internally.

The 9G0948M2D011 DC Fan is a high speed, oil-impregnated bearing fan designed for a wide range of applications. It features ball bearings, a thermistor, and an engineered impeller with backward curved blades to provide higher air pressure at comparable speeds. The fan also has an EMI shield to protect against electro-magnetic interference.

The application field of the 9G0948M2D011 DC Fan includes cooling in enclosed avionic equipment, systems with electrical boxes, and outdoor enclosures. Its wide range of applications include cooling printed circuit boards, motors, and other electronic equipment, as well as acting as an exhaust for printing and baking processes.

The fan works by the principle of airfoil lift. Its backward curved blades enable it to draw in ambient air and push it out at higher pressure. This is a similar principle to how an airplane wing generates lift, only in reverse. As the fan blades rotate, the relative air velocity increases due to the change in pressure between the fan’s front and back sides.

The 9G0948M2D011 DC Fan also integrates with a thermistor, or temperature sensor, to monitor temperature and adjust the speed of the fan accordingly. If the temperature rises and exceeds the predetermined setpoints, the fan will increase in speed to maintain thermal balance. It can also be used in direct contact with object being cooled such as an electronic component, where the fan will maintain cooler temperatures by pushing out hot air created by the component.

The 9G0948M2D011 DC Fan is a versatile and reliable fan that can be used in a variety of applications. It is an important tool for cooling within electrical devices and equipment, and is an effective way to maintain stable and healthy temperatures for machines and components.
