Why is my fan making squeaking noises?

"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."

Why does my HVLS  fan have a high-pitched squeal?

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."

Why does my fan have a  loud, roaring noise at full speed?

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.

How do you size a ceiling fan for a warehouse?

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.

What is the price of HVLS Ceiling fans?

We used to sell imported 8ft  fans for $600 . However, they only blew 2lb of air and the electronics often failed. We got tired of it and now only sell our own fans. They blow between 20lb and 150lb of air and the price is between $2500 to $6000.
