Industrial fans are essential for providing movement of gas and air in factories and other industrial applications. They work by stirring the air in enclosed spaces enabling you to replace contaminated air with fresh air. Usually, industrial fans come in different types to meet your specific needs. One of the popular industrial fans used today is a duct fan and blower system. This type of industrial fan system has several technical aspects that require your attention to make the most of your installation. The following piece outlines some of the essential details you need to know about industrial duct fans and blowers:

The Practicality

Industrial duct fans and blowers are a go-to option for spot cooling in commercial and industrial settings where ordinary air conditioning systems won't suffice. The circulating fans added to industrial duct fans and blowers are efficient at dealing with heat stratification, air stagnation and dampness. The duct fans deliver good results for high-volume and high-static pressure applications. On the other hand, blowers are ideal for areas where you need to remove stale air and replace it with fresh air from outside.

The Types of Industrial Duct Fans and Blowers

You have several options when it comes to industrial fans and blowers. Some of these include:

  • Positive displacement (rotary lobe fans): Positive displacement fans and blowers come with multiple co-rotating and serpentine shafts meshing to move gases and air in a regulated manner. The shafts work in a way that prevents air backflow and keeps the conditions stable in the space. Usually, tri-lobal and bi-lobal fans circulate air in processing facilities and areas where you desire consistent operating conditions.
  • Axial Fans: Industrial duct fans and blowers can also come as heavy-duty propeller fans, tube axial fans and vane axial fans. In this set-up, the fan blades move parallel against the airflow, delivering a fresh wave of air amidst the turbulence.  
  • Centrifugal fans: Industrial centrifugal fans and blowers come with different blade designs. These include the forward curve airfoil, radial tip and backward incline. All of them rotate perpendicularly against the flow of air. When choosing, talk to your vendor to ensure you get a product that will meet all your performance requirements, considering the range of products available here.

The Standard Required

Industrial duct fans and blowers must meet specific standards considering the long operational hours and environmental parameters. The best way you can check is by looking at certification marks on the products you are buying, ensuring that they have passed all the required tests for installation in your facility.
