MC61M 5,300 CFM 3-Speed Portable Evaporative Cooler

Awesome Evaporative Cooler. Im Glad I purchased this larger unit. Simple trick is. The cooler the water. The cooler the breeze. Its as simple as that. Great Fan. Easy to operate. Easy to clean. And YES! Only 3 simple controls. It's really that easy. People complain about build quality. Well. The unit is. General is surrounded by water. So minimal metal can be used. But its sturdy enough. As loud as your ordinary household fan. But it WORKS! NICE ball bearing casters that you install with provided screws. Love it.

Working in the heat? Is it dry? Because if so, this is the solution for you! This thing works great. I use it in an automotive shop where summer temperatures routinely break 110 this thing will cool the air 25 degrees no problem, given low humidity. On low it’s barely noticeable from a few feet away, on high it makes some noise but it MOVES SOME AIR! It’s the perfect size to roll around, the tank will last 4-5 hours. The oscillation feature is nice for covering a large area. 5/5 stars, can’t recommend enough

I bought this unit to deal with indoor high heat during heat waves in Northern California. Yesterday I unpacked it and set it up. No hardware was included with the castors - no problem, I have some screws and a tiny screwdriver. Filled up the tank - it is very large and a lot of waters goes in before there is any movement on the gauge. Once filled, I plugged it and turned it on. Pump worked, fan did not work. No problem, there is a small trouble shooting manual that comes with the unit. Unscrewed the back, removed the filters, found the obstruction that was blocking the fan, put unit back together. The working fan blows out a lot of lovely cool air. With a lot of noise. On the first try, the unit lowered the temp in the area I was cooling from 88 to 81 quite quickly. I'll continue to experiment with it in different areas to see what it can do. It is easy to see why it is called a swamp cooler - there is a definite swampy feel to the air in enclosed space (other than the open window behind the unit). The space I am cooling is quite large and has high ceilings, so the drop in temperature was pretty good, and it was fast. I have yet to figure out if its worth the price tag.

Great design overall! This is one of my favorite new purchases in years. I use a hand truck to wheel it over my lawn to my back workshop. Works great in Utah's dry air! I've also used it for patio parties and for keeping cool while changing my oil. I even loaded it into the back of my 4runner and took it to St. George for a family party. It was a hit! I did add some strain relief to the garden hose connection using a 1/2" F barbed funny pipe elbow, a length of funny pipe running vertically to the top of the unit, a couple of 8" zip ties to hold the funny pipe to the electrical cord winding post, and a 1/4" M barbed funny pipe elbow. Version 2.0 would be nice to have that built in. It would also be nice to have some handles on the sides for when you're wheeling+lifting a full unit over raised cracks in concrete - as it is now I have to grab the plastic grill on the side and I'm worried I'll break it. Neither is a deal killer. This thing has made it possible for me to work in my shop all summer, not just spring and fall, and for that I cannot be more grateful!!

Colorado. 100 degree 18% humidity, insulated garage (approximately 900 sq ft) push cooler up to sliding window screen door. Window opened enough to allow air to flow in thru screen. Vented to attic . ( hot enough and well ventilated to dry out any humid air from cooler through daylight ) Started at 84 degrees in garage after 3 hours down to 79 . Have started early in morning on 95 outside high and been able to cool it down to 73 . About 65% humidity. I can work about 10 feet away from cooler and it feels comfortable to work . Also can supplement with another fan it the air path to push the air farther, air measured at outlet at 71 degrees on 100 degree 18 % humidity day. Great cooler makes garage work bearable in dry climates. Have used with up to 50% humidity low 90’s and if in air path still fairly comfortable. Recommend.

The package arrived in a timely manner and there was no sign of damage. But the bottom storage space that was supposed to contain the hardware and wheels was open and the hardware bag was missing. Be careful as using the wrong size screws to hold the casters on will result in a the tank leaking. The Internal cooling honeycombs were not installed correctly and were floating around in the water compartment and had come in contact with the fan when it was tested during assembly. There were bits and pieces of honeycomb all over the place. I was able to correct the assembly issues. Having no way to install wheels, I placed the unit on a furniture dolly and made it mobile. I found the brass fitting needed to connect a water hose to it at the local hardware store for about $5. It took some doing to get it going, but the fan and pump work good so the unit is cooling. I tried contacting the seller and got no response. Contacting the manufacturer and requesting replacement parts via the website is impossible.

We were moving from one Warehouse to another in the middle of June summer heat in Utah and our new location did not have AC. I ordered one and was very skeptical about the quality, but I was very pleasantly surprised. It arrived completely assembled (the optional wheels are included, and I chose to put them on which took all of 2 minutes). It was instant relief from the heat, and has worked perfectly all day everyday for several weeks now. It is not supposed to cool off a warehouse as large as ours. We are in about 8,000 square feet, but it makes a HUGE difference. I actually ordered a second one so I could put one on each side of the warehouse. Highly recommended. They both work perfectly. Because I didn't want to keep the hose attached at all times, I rigged up big water tanks on top of my units that hold 20 plus gallons of water so that they can go for the entire day without needing to be refilled.

I probably wouldn’t purchase this again as we have to keep adding water and the spot is so small it takes too long and have to fill it too often. It interrupts production. We ended up getting a small hose so we could just turn on the tap to fill it but it wasn’t a great solution. Someone forgot they were filling it and left the trap running which flooded the area. We had high hopes but it didn’t work very well for us. 🙁
