Are you planning to buy industrial process fans or blowers for your manufacturing 
plant or factory? You should consider a custom-built industrial fan for your factory as 
they can exactly cater to the desired specifications and air-blowing requirements.
Standard fans are also available in the market. But, remember that they may not 
always be suitable for your factory process requirements. In such situations, custom-
built fans are ideal for any size process – all that is required is an industrial fan 
manufacturer who can build a fan to your factory process specification.
Industrial process fans can be custom built and a quality industrial fan manufacturer 
with extensive engineering expertise in customizing variations is to make a smart 
decision.
Introduction to industrial process fans
Industrial process fans are highly efficient fans or blowers that are generally available 
in various sizes, configurations, and customized with various materials. There is a 
wide range of process fans available with various designs and sizes for various 
industrial purposes. If needed, for a particular manufacturing process, these are 
built with exceptionally durable material to withstand harsh factory conditions like 
extreme temperatures. The working conditions of industrial processes can be very 
harsh and the blowers must work for long hours or continuously based on the type 
of process.
To ensure such quality, even the smallest components like bearings need to be of 
high quality and built with quality materials and processes. Based on the fan 
specification, the fan components are built with special quality materials with pre-
defined metal purity or thickness. Attention is also paid to things like the quality of 
welding in the fan construction and several protocols, methodologies, and quality 
control practices are followed for ensuring a high-quality process fan.
Types of industrial fans
For a person who is not aware of the intricacies of industrial process fans, wrongly 
assume all fans are the same. In reality, there are so many technologies and 
specifications with which a variety of fans are built including airfoil fans, backward 
curve fans, backward inclined fans, radial blade fans, radial tipped fans, paddlewheel 
fans, forward curved fans, inline duct fans, tube axial fans, vane axial fans, and 
variable pitch fans to name a few.
The key thing to remember is that industrial process fans help automate and process 
various industrial activities and based on the specific process either a standard fan 
or a customized industrial process fan is used to facilitate efficient manufacturing.
Utilities of custom-built industrial process fans
The utility of industrial fans ranges across a variety of factory applications – there are 
a large number of factory processes in which the process fans are used.
• Material conveying: Custom fans are very popular in conveying air and small 
particles into furnaces in large volumes. In this process, the industrial process fans 
do the work smoothly.
• Combustion air: In a variety of factories especially those involving a combustion 
process – the industrial process fans are used for providing furnace air to facilitate 
the combustion process.
• Airing and drying: Some process manufacturing requires cooling and drying of food 
products. The huge blowers help in the reduction of water content in food items. 
Fruits and vegetables rot in damp conditions and therefore these fans help in the 
prevention of mold and bacterial growth.
• Exhausting waste gases: A layman or non-factory person can easily relate to the 
prevention of concentration of any toxic gases or intense smells by using fans for the 
exhaust process. Warehouse and packing areas also require air purification and 
removal of humidity. These fans make it comfortable for the staff to work in the 
factory.
• Cooking fume extraction: One of the prime use of custom-made industrial process 
fans are in the cooking, sector. To remove the fumes and smell, massive extractor 
fans become mandatory. These are basic health and safety products.
• Packaging: Many manufacturing units have a pneumatic conveyor that uses a 
stream of clean air to transport small items. Here high pressure custom industrial 
fans help in holding the receptacles firmly to the belt during the packing process. 
Fans help in inflating the packaging process.
• Coolant fans: Custom-built industrial process fans are ideal for cooling materials 
before the next process can commence in the factory. Cement clinkers are first 
cooled before being sent to the next process in cement manufacturing.
• Pre-heating: Pre-heating of fresh air ensures the efficiency of combustion in 
industrial furnaces. The atmospheric air drawn to support combustion is heated 
using the exhaust air or flue gases and heated air is supplied to the furnace for 
efficient combustion.
The above is not a full list of applications of industrial process fans but only provides 
an overview of possible applications. You can decide to install either a standardized 
fan for your manufacturing process or order a custom-built process fan for your 
manufacturing requirements based on the manufacturing requirements.
