Ceiling Fans in Garage

[macs shop]

I have 3 Menards 56" industrial ceiling fans all wired to a single speed control. They are hung down the center of the shop. Actually just got them running last week and at their lowest setting they have the faintest hum to them. I'd say they're right at 60 rpm or so and help keep the air stratification to a minimum. I'm not fond of higher velocity air. It's annoying to me, so I favor the lower speeds.

Zombie thread, I just ordered 2 of the 56" from menards, they had them onsale for $39 each. How did you wire multiple to the same speed controller?

I just bought the same Menards fans because of the sale. Going to put 2 on the covered/screened deck. Most "included" fan controllers are for a single fan and rated at 1.5amps or less. So putting 2 fans will overload the controller, and cause humming. All of these fan controllers adjust capacitance to make the motor run at different speeds, same with the pull chain switch on the fan itself.

I bought this 5 amp multi fan controller for about $20. Shows out of stock though?

Lowes has the 72" nine blade Fanimations on sale for 269 this weekend. Going to get at least one, lol

I had an OLD faux White 42" in the old shop to move air. The new Shop needed one. Pretty soon after the house down the road sold, two 42" brushed bronze fans were out in their Trash!

Be careful when using an iron to solder, cold solder joints can happen when the solder joint cools too quickly.

Of course! 10 foot ceiling me, and seems on all the time out there....

In summer heat - The answer is to with some method vent out hot high air... then use horizontal blowing fans blowing where you are working.

Update on my "free" fans!
Since I put it up I noticed less air flow. Studying it I realized the old fan has a 16 inch tube suspending it which makes it closer to me. The new one only has a 6 inch tube which makes it farther from me.
Is there a "Design" sweet spot that a fan should hang from the ceiling to get maximum flow with minimum turbulence or restriction from the ceiling?

I'm no engineer but it seems to me 16" would allow better movement than 6"

Further, I think safe assumption that at 16" you pretty much allow max flow.
