"If your fan produces a squeaking noise, it could be due to the belt slipping. This typically happens when the belt has been in use for a long time and has become worn.
Replacing and properly tightening the belt should alleviate this issue. Consider direct magnet drive fans that eliminate belts and gear issues."
If you notice a high-pitched squeal that changes with the motor's RPM, it might be due to the carrier frequency parameter of the Variable Frequency Drive (VFD). This parameter typically ranges from 4,000 to 32,000. Increasing it can help reduce the motor noise. However, a higher carrier frequency might cause the VFD to heat up more quickly, so monitor the temperature closely."
Sometimes, a fan will produce a loud, roaring noise when running at maximum speed. This is often due to the particular fan's design. In this case, the best solution is usually to run the fan at a slower speed. If the noise persists, consider switching to a backward-inclined fan, which is designed to handle high pressure better with less noise.
The easiest method to size a big HVLS ceiling fan is based on the number of people working in a 100ft area. If it's only 1 person,, a fan will cover 8x its diameter. If many people are physically working and edges are important, a fan will cover 4x its diameter.
We decided to install Ameriwind fans rather than circulating fans because there was not a big difference in the initial cost of the fans. Plus, the cost of running the Ameriwind fans is considerably less because they require less voltage. And, the Ameriwind fans push air down and creates air movement between the cows and throughout the barn.
I manage the shop and do the really technical repairs after hours for better concentration. If I leave the doors open, people keep coming. If I close the doors it gets so hot. With the big 18” AmeriWind ceiling fan, I can leave the front doors shut, and it's still comfortable. I really appreciate how well the fan works.
We first had another brand of large ceiling fan in our shop, then we also installed several AmeriWind fans. The AmeriWind fans move the same amount of air, but they don't make near as much noise. We like the fact that AmeriWind is a direct drive so it doesn't have a noisy gearbox like the other brand.
We eliminated the mold on our pallets by installing 6 AmeriWind fans above our pallet storage area. The fans have worked very well
