I tried swamp coolers when it was still in the low 100s here in Phoenix, AZ. They did not work or keep my shop cool enough for the GF. Evap coolers just don’t work well enough for the heat, I’m afraid. The good news is I now have a portable air conditioner unit that blows directly under the GF, and they both vent out the windows. That works much better.
