It is a fan that is placed in the ductwork in your home to move air from one part of the house to another.A propulsion arrangement is seen in ducted fans.The air is thrown upwards or in forward motion by the duct thereby affecting the pressure of air and its velocity.To remove fumes,dirt-laden air,steam,hot air and smoke,duct are generally used in many industries or places where these problems are encountered.fans have great many advantages as it is also to supply air for cooling,drying and ventilation.
The belts of the motor are also often adjustable to ensure optimum speed.Another important feature of Industrial Panel Fans is the pillow block bearings.Industrial panel fans may not be fancy to look at but they usually have a good quality enamel finish so that they look good and can resist wear and tear in an industrial atmosphere.The propellers are also made of steel to make them strong and long lasting.As opposed to industrial panel fans,fans are also industrial fans that are fitted in a closed environment to expel chemical fumes and gases that are produced in a manufacturing process.Based on different needs,though the fan manufactures design fans but some of the design parts are common.To prevent resonance in the duct,ducted fans usually have an odd number of blades.
Temperature is another factor in the design of these fans where they have to be built and used.Aircraft fans have more and short blades and therefore operate at higher rotational speed.These Duct Fans are used in hazardous places such as booths used for spray painting etc.Since duct fans are not continuously used,they usually have aluminum propellers that are much lighter than steel ones.Duct fans can be used most effectively in a clean and dry environment up to an ambient temperature of 180 degrees Fahrenheit.Belts and sheaves of fans are protected in an air-tight covering so that they are not affected by the chemical fumes and gases that are emanated from the process.Special industrial duct are available for use in high humid conditions.All the parts of such duct fans are protected from moisture and grime so that they function at their optimum capacity without any problems.Some duct fans are specially made to withstand very high or very low temperatures and function well giving optimum output.
