Centrifugal Fans & Blowers

Centrifugal Fans for Industrial Process Applications

AirPro designs, produces, delivers, and services heavy-duty industrial process centrifugal fans and blowers. They’re the only kind we make. We do not produce any commercial or residential fans or blowers, nor do we design or manufacture axial fans. This focus on centrifugal industrial process fans means we can run fast and lean with consistently high quality and reliability.

Manufacturing systems use centrifugal fans to move air, gas, and raw materials through processes across the operation, resulting in an end product. Process fans drive process air to act as a change agent across various types of transformations within the industrial system, whether in materials, the assembly, or the environment.

Types of Centrifugal Fans & Blowers

Centrifugal fans come in a variety of designs. Our application engineers design all of the centrifugal fan and blower components to accommodate an application. Some common design criteria are the size of the motor, the shape of the fan blade, the direction of rotation, and the materials of construction. AirPro offers a comprehensive selection of centrifugal fan designs including:

Each of these centrifugal fan and blower types has its own unique performance characteristics. Which industrial fan type you need in your process to achieve efficiency and reliability depends on airflow volume, static pressure, and what the fan is processing (clean air, mild particulate, or highly abrasive materials). Once you know those variables, you can work with us to specify the right fan for your application.

Product & Service Reliability

We can’t talk about our products without talking about reliability. The quality we put into our fans and blowers is the reliability you put into your essential operating processes. That’s why we guarantee all of our products with an industry-leading Gold Standard 3-Year Warranty. It’s the drive behind our determination to deliver on time, whether the order is expedited or not, custom or standard. And it also applies to expedited service – repair or retrofit on our own or another manufacturer’s fan or blower. We insist on reliability in our products, processes, and people, and you can count on it.

Centrifugal Fan & Blower Safety & Maintenance

AirPro inspects, tests, and engineers industrial centrifugal fans and blowers to meet the highest levels of quality and safety. AWS standard certification and Quality Control documentation accompany every shipment. Our products are also CE Certified and ATEX rated.

Proper maintenance is critical to the successful operation and long fan life. In every possible case, our centrifugal fans and blowers contain features that make routine maintenance easy. To accommodate gases or materials in the airstream, add protection, and increase the life of the product, we add special finishes including industrial enamel, specialty paints, powder coating, and custom linings.

How a Centrifugal Fan Works

Fan Assembly Broken Down
The rotating fan blade creates a low-pressure area at the center of the blade and a high-pressure area at the edges of the blade. It also adds kinetic energy to the air. The low-pressure area at the center of the fan creates a vacuum that draws air into the fan. The air flows from the center of the fan to the outside edges of the fan. Ultimately, it flows out of the enclosure around the impeller in the desired direction. The design of the overall system accounts for the 90-degree turn in the flow path.

Industrial Applications

Industrial centrifugal fans and blowers accommodate a variety of applications. For example, chemical processing, corrosive gas handling, dust collection, dryers, fume control, process cooling, and process heating. Below are some of the most common, with links to more information and related fan designs.

5 Common Centrifugal Fan Applications:

Clean Air Handling

In industrial operations and facilities, air movement is always part of the process. Air handling fans support your operations and the ambient air in the vicinity. Processes span from industrial system components to makeup air units and removing to refreshing. We design and build centrifugal fans specifically for your industrial clean air handling application.

Light Dust Loading

Industrial processes use light dust loading and fume extraction fans as part of the overall dust collection system for air quality improvement and safety. They move the air and materials through the system to capture, collect, and convey the particles through various parts of the system. These can include hoods, air filtration, a collector such as a baghouse, traps, and of course ductwork.  Learn More

Material Handling

Centrifugal force material handling fans can process particles such as sand, plastic pellets, sawdust, wood chips, grain, paper trim, pet food, and countless others. They range from small and light to larger, heavier, and more abrasive. AirPro has been innovating based on customer input and building industrial material handling fans for years with increasing efficiency and durability. Learn More

Saturated Air Fans

Centrifugal exhaust fans frequently process saturated air, meaning there is moisture from humidity or various gasses in the air. These applications often require heavier duty materials like stainless steel and moisture-resistant coatings like epoxy. When we engineer custom fans, we start with an appropriate fan type and tweak the materials, finishes, and other specifications. Learn More

High Temperature

Many industrial processes rely on high-temperature process heat. Operations like heat treating, stress relieving, industrial furnaces, and ovens use convection to circulate heated air within the chamber. These process airstreams require specially designed centrifugal fans. Fans not properly designed for this purpose will catastrophically fail when used at temperatures above their design. Learn More

Customized Centrifugal Fans

Industrial fans need to meet a specific set of design criteria. We recommend working with an AirPro fan selection expert to design the best fan for your application. You will be working with industry-leading fan engineers to create customizable solutions to match your project requirements and budgets.
