What is a Balanced Fan? Think “Finishing the Job.”
A balanced fan must stay below specific vibration limits for safe operation while running at full speed. Excessive vibration will decrease the life of your fan and can lead to catastrophic failure.
Welcome to the AirPro Blog
With a focus on robust construction, we built a process fan on a combustion blower for an industrial heater application. This installation called for a backward curved blower with a direct-drive motor and an outlet damper with an electric actuator and positioner. We designed it with fewer parts to reduce maintenance in the industrial environment.
Fan Selection Considerations
We all know fans move air, but in industrial applications, they also move particles, parts, and even products. Both Mass Flow Rate (movement of materials) and Volumetric Flow Rate (movement of air) are important to know when calculating fan specifications and performance.
Why and How to Vary Speed in an Industrial Centrifugal Fan
A variable-speed fan is just what it sounds like. In this case, we’re talking about an industrial centrifugal fan that is capable of operating at more than one speed. That means it can run above or below the constant motor speed specified. There are several reasons why you would need a variable-speed fan, several ways to do it, and a few things to be careful to avoid when operating at varied speeds.
Radial Tipped Return Air Fan for Dust Collection
We built this radial-tipped dust fan for an air return application in a dust collection system. The fan has a 125 HP motor with roller bearings and a V-belt drive with the fan and motor mounted on a unitary base. We included a custom color coating to match the rest of our customer’s system.
Keith White Jr. Steps into President Role as Keith White Sr. Shifts to Board Oversight
We’re thrilled to congratulate AirPro Fan & Blower Company founder Keith White Sr. as he moves closer to retirement in the role of Chief Executive Officer focused on Board oversight, with Keith White Jr. stepping into the role of President as of July 1, 2023. The transition is the culmination of our years-long succession plan, with co-founder Marty Mathews retaining oversight of engineering and technology development.
Use a Damper to Add Resistance and Reduce Airflow
If you want to reduce a fan’s air volume and horsepower without adjusting speed, then you can use a damper to add system resistance. The damper can be installed on either the inlet or outlet side of the fan, and you can determine the best location based on your specific application and your fan performance curve. More often than not, we’ll recommend placing the damper at the outlet as the most cost-effective way to simply add resistance.
In this air pollution control installation example, we designed and delivered a heavy-duty fan for an OEM who designs and manufactures thermal oxidizers. This backward-curved induced draft fan is an arrangement 8 direct-coupled drive with a flexible coupling.
In this asphalt plant installation example, we designed and delivered the industrial fan for an asphalt plant equipment OEM. The induced draft backward-curved arrangement 9 fan included a dual drive with two 150 horsepower motors, delivering 300 horsepower combined.
We designed these custom replacement swing-out fans for paint booth systems in an automotive plant. The swing-out fans provide easy access to clean and replace fan parts. Our design helped the plant overcome supply chain problems in sourcing fans and fan parts. The fans have backward inclined blades and include an outlet damper.
This direct-fired burner fan was designed to move over 150,000 cfm of clean air for a biomass energy application. Featuring our backward-inclined design, the fan wheel is 89 inches in diameter and operates with nearly 80% static efficiency.
This biomass pyrolysis installation required a fan that can handle abrasive material, gasses, and high-temperatures. We designed a custom radial fan, also known as a paddlewheel fan with an open radial blade design. It featured double-walled housing with thermal insulation and alloy airstream materials to handle high temperatures up to 1500°F. We also built it with a continuously-welded housing interior and a bubble (air-leak) pressure test.
We replaced an industrial exhaust fan originally built by another manufacturer in this brine vapor retrofit installation. The fan is an open radial blade paddlewheel design with a backplate to protect the motor from the material in the air stream. We used AL-6XN® construction material for corrosion resistance and a stuffing box shaft seal to prevent vapor leakage.
We designed this calciner supply fan for a high-temp rotary kiln application. Featuring a radial tipped fan with a v-belt drive and a unitary base, it withstands temperatures up to 475°F. This heavy-duty, radial tip fan moves high volumes of air at low static pressures with high efficiencies.
