Hey all, our new shop is pretty damn hot, 95° plus, so we're checking out the assorted offerings of roof ventilators, powered and non-powered. Anyone have any opinions to share? About the ventilators I mean, lol...

ventilation direct seems to be a good source. We bought a large fan and had them build another housing.

We just installed two 20” wall exhaust fans. It makes a noticeable difference.
Northern Tool.

It's 95 outside here. Biggest AC you can buy. Pipe it down directly on top of operators. Really makes them hustle to do setups so they can get back under it.
-
We have 3 large fans maybe 30-36 inch fans I think installed high on our side wall pushing air out. Dropped temps around 5-10 degrees.

We have a louvered exhaust fan on the side of the building, this is a great option if you don't want to punch a hole in the ceiling, it's much harder to get leaks around these.
We also recently installed a big 1200cfm exhaust fan to pull the spillout heat from the oven. We figured capture it at the source. That has helped more than anything else in the shop.
We also run a portacool 48" fan. That helps a lot too, but the name of the game with that is air exchange. You need to be pulling air out faster than the portacool is bringing it in. Otherwise it gets very humid and that doesn't help at all.

Got a image of that on how you did it?

Here you go! The ends are metal boxes, 12h, 18d x 54" wide. I wrapped them in 1.5" ductboard because they were pretty hot. We are going to insulate the rest of the ducts when we have some downtime.
We paid an HVAC guy to do it. It was easier to let him order the roof curb and have everything fabricated.

Do they make a lot of noise? I`m looking as well at options for a wall exhaust fans. Where did you buy those?

Our new rig is almost silent FYI, the fan is mounted outside on a custom roof curb. I am thinking of installing an indicator light on the circuit to notify us that it's on.

I would love a BAF but they are really pricey. They do work great though. There a few places near by that have them. They give a gentle breeze that makes it so much more comfortable!

We picked up 6 used warehouse fans for around $100 each. Very clean nice working fans with wall mounts. https://www.americansurplus.com/used-equipment/ (https://www.americansurplus.com/used-equipment /)Pushes air out of the building through the bay door. An improvement but not a total solution. Still very hot on the 100F day that we experienced yesterday. We wrapped our precision dryer with insulation and that helped as well. Still seeing a mirage from one side of the dryer to the other and tempers are getting hot with the weather. May have to run production 6am -2p as a stopgap. Probably wont be in this bldg too much longer so I don't really want to punch a big hole on the wall. Following this thread...

We have a couple portacool swamp cooler fans that seem to help out.

We've bought a bunch of spot coolers and fans from global industrial.

Now that's downright pretty...

You have no idea how much I want to give it a bronze patina and go steam punk with it...

great idea, if we only could afford to do that...

Um, since heat rises, and it's hotter at the ceiling, why would I want to push that air downward? Am I missing something? How does that remove heat?

I imagine it’s like most fans where in the summer you have it pulling air up and in the winter pushing the hot air down.

Not as much as we expected. You can have a normal conversation beside it. I think they’re rated at 77db.

I looked at one of those cooler fans but am nervious that the excessive moisture will effect the electronic boards of our carousel, etc.
They blow a lot of water into the air, we have one behind the oven.
At the moment we have regular fans aimed at the printers.
I read sometimes that people put Plasitsol in the screen drying room to warm it up, here the screen room is air conditioned and much cooler than the rest of the factory.
They must be in really cold places.

... tempers are getting hot with the weather...
Maybe you should try the approach my old shop used - a case of these in the breakroom freezer! ;D

We supply gatorades for the crew...

These seem to be better suited to more modern, or at least updated facilities. If we pull the heat up, it still has nowhere to go. It's looking like the through the roof option, though we do have one outside wall. Thanks for the input everybody.
