What is the standard drop length requirement for MacroAir fans?

View Details

• Standard 3 ft. drop requirement for most fans, requiring a ceiling height of at least 13 ft.; Many models can be shortened to a 2 ft. drop standard. An AVD370 model can be as short as a 1 ft. drop standard.

What is the minimum height requirement for a MacroAir fan?

• A fan must have a minimum 10 ft. height requirement above the floor, plus a drop length requirement of 3 ft. (the total required height from the ceiling to the floor is 13 ft.) Blade tips should be at least 3 ft. away from any area where a person may be able to reach them.

What is the required distance from the wall to the fan?

• MacroAir agricultural ceiling fans must be 1.5 times the diameter of the fan from the wall. For example, if the fan is 6 ft. in diameter, multiply  6 x 1.5 = 9. This means the ceiling fan must be 9 ft. from the wall.

What is the required distance between fans?

• Depending on the diameter of the MacroAir fan, take the diameter measurement (in feet) and multiply it by 3 to find the distance between fans. For example, if the fan's diameter is 6 ft, multiply 6 x 3 = 18. That means there must be 18 ft. between fans.

Do I need to keep MacroAir fans close to the ground for better air movement?

• No, fans do not need to be close to the ground. Keeping fans at a higher elevation allows for more air circulation.

People I have talked to about them say they are wonderful to keep air moving and so temperature more even.
Especially in the summers they help keep the barn from getting quite so stuffy and hot.

The down side, well, they keep the air moving.
In a barn, that means so much more dust/dirt up in the air than when they are not running.
That is not helping air quality in there much.

A trade-off every barn owner will have to make, what is more important to them there.

What some then went back to in their next barn, or say they would, is small individual fans for a spot in each stall, not the ceiling ones.
They seemed to think they could be hung where stirring up dust would be minimal.

I am not aware of any studies on what is best or why.

Will be interesting to hear what others say.
I too am wondering if we even need some and if we do, which kind would be best.
