A mechanical fan is a machine that is used to generate current inside a fluid, which is usually a gas like air. This is achieved by rotating a number of blades connected to a hub and shaft that are driven by an engine or turbine. The flow rate of fans ranges from 6 to 60,000 cubic meters per minute. Blower is another name for fans in which the flow resistance is high on the downstream side of the fan.
A fan consists of a rotating set of blades or vanes that move through the air. The rotating assembly of blades and hub is known as impeller or propeller, rotor or runner. Usually, the fan components are placed inside some kind of housing that may direct the air flow in a way that prevents objects or fan blades from hitting and increases safety. Most fans are driven by an electric motor. But other sources of power, including hydraulic motors and internal combustion engines, may also be used.
Fans produce air flow with high volume and low pressure (although higher than ambient pressure) and are the opposite of compressors that produce high volume in relatively low volume. A fan blade often rotates when exposed to a current of air, and devices that use this feature, such as anemometers and wind turbines, often have a fan-like design.
Applications and Industries Uses Industrial Fan
There are many uses for the continuous flow of air with gas produced by industrial fans; including combustion, ventilation, aeration, movement of particles, discharge, cooling, air purification and drying, the industries that the fan serves include electricity generation, pollution control, metal production and processing, cement production, mining, petrochemical, Food industry, refrigeration and clean room.
applications of different types of fans
Among the uses of this product, the following items can be mentioned, it should be mentioned that the following list is some of these items and basically the fan has many uses.
Fan Types
Fans with rotating blades have various designs. In a house, you can see floor fans, table fans, ceiling fans, etc. Fans can be used in electrical systems such as computers where they cool internal circuits, or in household appliances such as hair dryers, portable heaters, and wall heaters.
