Thunder Bay, Ontario, Great White North | We have 3 24' fans in the center line of my 86' x 180' freestall barn. They work really well, quiet and move a lot of air at full speed.
The manufacturer of my fans mounted the vfd beside the motor on the fan itself, this is supposed to eliminate any problems with interference.
Nice that they push the air down into the cows as opposed to just moving air across their backs as in a tunnel ventilated barn. |
Big ceiling fans ? [freestall barn]
