All the ones I have seen in factories and warehouses were reversible where I noticed one way or the other. I guess I always assumed that was the common thing.The key to productivity is to keep people happy, and comfortable. Not make them miserable. But this isn't an HR forum. It's an electrical forum.
I simply asked about a reversible fan.
I find they often don't really know what they actually need.Could be that is what the customer asked for.
Haven’t done one lately, but seems like their controller does have a reverse button on it, but that being said, I would not think the air foils on the ends would work well backwards.Funny thing is, Grainger sells BA fans, & the specs say they are reversible.. BA fans are for decorative spaces, where people admire a fancy piece of equipment. We never installed one. My gym has one... nice to look at, but $6,000.....
