Industrial fans are the machines that perform the primary function to provide and accommodate a large flow of air or gas to the various parts of the spaces you have. The fan consists of a hub and shaft with a number of blades rotating and providing the airflow and is driven by a motor or turbine. A blower is another name for a fan that operates where the resistance to the flow is primarily on the downstream side of the fan.
There are many uses of industrial fans including combustion, aeration, and ventilation, and particulate transport, exhaust and drying. An industrial fan is just one of the various elements that make up the ventilation system. Keeping other elements unchanged, the shorter is the duct the more effective the consequence is. The incoming airflow is always clearly defined, and the output airflow can be oriented in many directions.
Types of Industrial Fans
Industrial fans can be classified into two types:
Centrifugal Fans –The centrifugal design uses the centrifugal force generated by a rotating disk with blades on the right angles to the disk, to blow air and increase its pressure. The wheel of centrifugal fans contains scroll-shaped fan housing, resembling the shell of the nautilus sea creature with a central hole. The gas in the fan is blown out to chill the space where the fan is positioned. Inlet and outlet ducting are usually attached to the fan’s housing to supply the gas. Again there are many types of centrifugal fans but we are not discussing that in our article.
Axial Fans –The axial fans are generally used where the requirement of air is for a large volume of flow. The axial design uses axial forces to achieve the movement of the air. The fluid is moved parallel to the fan wheel’s shaft or axis of rotation.
Components of Industrial Fans
There are many components of industrial fans and they perform certain functions which are discussed below:
The Inlet Cone: The inlet cone is a component for directing air into the fan housing. It performs certain functions which include, link the fan to pipes. Inlet cone varies from one another as its dimension and shapes depend on the type and function of the industrial fan.
The Impeller: This is known to be the heart of the industrial fan. The rotating components on which blades are placed are known to be the impeller. This is the main component of a fan.
Fan Housing: Fan Housing is the structure that contains the impeller and the air to be passed through the housing and it moves towards the ventilation system. After that, the air in the housing gets compressed and its speed increases. The performance of the fan depends on the shape of the housing.
The Inspection door: This is known to be a small door placed on the case. It is very useful for performing extraordinary maintenance.
The Motor Pedestal: This is the support of the fan where the fan is installed. In industrial fans of big size, the pedestal is directly welded on the case.
The cooling wheel: It is a small impeller which is slipped on the impeller hub for direct-driven fans. The cooling wheel is used to dispose of the heat of the airflow which blows through the case.
Provided here is sufficient information about Industrial fans which may help you in some way while you plan to opt for those. The choice of the right industrial fans with the right discharge position is effectively needed in order to get the best performance from the ventilation system.
