Description

Evaporative cooling fans are designed to pull hot, dry air through a water- soaked media filter using a water pump and fan. As the water evaporates into the air, the air's temperature will lower. They are optimal when used in hot, dry climates used to filter ambient air while increasing the condensation and delivering cool airflow. Evaporative cooling fans do not use refrigerants to remove heat like an air conditioner, so they are less effective in high humidity areas.Hessaire’s MC37M is the best and most effective cooling fan on the market for its size. It’s compact and yet packs a powerful blast of cooling with a patented winged prop design and three panels of high-density rigid media. Take it on the go easily with its four casters. It features oscillating louvers to cover a wide area quietly and efficiently. The manual controls make it easy for you to adjust between the four temperature settings to obtain optimal cooling anywhere you take the MC37M Evaporative Cooler.Cooling the air is only a part of the process; propelling the chilled air into your space is what brings you needed relief. Specially engineered features from Hessaire allows this mobile evaporative cooler to provide an airflow of 3,100 CFM to your area. Proprietary fan propeller design with winglets throws the blast of cool air further and yet is very quiet. Additionally, the air swing delivery system moves cool air left to right across the room to ensure that air is evenly distributed.

  • Powerful cooler
Size: 3,100 CFM
I waited until the end of summer to leave my review, so I could have an idea of how this evaporative cooler would hold up after months of use. I live in So Cal, and specifically bought this for work. I work in a large outdoor booth without any kind of cooling. After several summers of suffering from sweltering heat, I finally decided to take the plunge and buy a portable swamp cooler. Initially I was hesitant, as a few hundred dollars is a lot to spend on something I’d likely only use for 3 or 4 months. But I am sooo glad I did! This cooler really does blow out cool air! I was surprised and delighted! The wheels glide across the concrete floor with ease, and the drain is easy to plug and unplug. I don’t have access to a hose, so I can’t attest to how the hose connector works. But it’s very easy to add water manually. And no leaks! You can also add small chunks of ice, although I don’t think using ice made much of a difference. Also, the little window showing the amount of water left in the tank is very convenient. Be prepared for the air flow being strong, and a bit loud. Even on low, which is the only setting I used. Being outdoors a little noise is not a big deal. But I think it might be too loud to use indoors. If I have one thing that’s negative, it’s that the latch on the manual fill door, which is only a tiny piece of plastic, broke after a couple of days. All in all, this portable cooler works great and was worth every penny! ... show more

  • This baby is powerful and actually works.
Size: 1300 CFM
My AC for my home went out and needs to be replaced. Even when it worked it only worked on the main level and not in the basement. I started out looking for AC units that do not need to be vented for my basement and purchased some 2 in 1 breezewell units. The first one I got worked pretty well. When my main AC went out I thought well maybe as a temporary fix I oould buy a few more. I had bought a 2 in 1Breezewell and a 3N1 Breezewell. The 3N1 was smaller and I was a little disapointed but, I have had no problems with it. The 2n1 unit seemed to be working well and so I thought I would buy one more. The day after I bought the 3rd one the second 2n1 unit quit blowing air after 5 days. Nothing I could do would fix it. I did all the troubleshooting suggestions that came with it. I reached out to the seller with no success and then the third one arrived I thought ok the other one going out must be a fluke so I hooked up the third one relieved that it was working. Until the next day when the third one quit blowing air. Now I was furious. It was hot and I had spent too much money of these units. I contacted Amazon who by the way are the best cutomer service people I have ever worked with. They got me a refund and I was able to order something else. Not trusting the reviews on Amazon I went out to Google and searched for the best AC that did not need to be vented and this little baby popped up on a Bob Vila website on top evaporated coolers. It did not look that great. It did not have the bells and whistles that Breezwell had but, after reading reviews I was convinced enough to give it a try. I live in UT which is a dry climate and the reviews from California and Nevada who have similar hot dry climates were very convinving. When I got it there was nothing to really put together but to attach the wheels on the bottom of the unit and add water. When we turned it on we could tell how powerful it was. It takes 4 gallons of water. But, when you turn the fan on with the pump, the air coming out was very cold. Almost like a refrigerated unit. It cools the entire room down to the point I have to turn it down because it gets too cold. That is without adding ice or anything like what my breezewell was recommending. You can put ice in it but you do not need to. Maybe I will try that on the hotter months. This AC is strong and has strong fan that blows the air out. I do not mind the sounds. I am pretty sure it is a little quieter than the Breezewell that bills itself as a quiet unit. I compared the force of the fan with my working breezewell and this one is stronger, ,colder and I am happy with it. I finally found a unit that really works. So what are the negatives? You have to watch the water level and you will need to fill it up about every 4 hours if you run it all the time. You have to do this with all evaporated coolers from what I can see but, this one uses 4 gallons of water. I will sometimes turn off the pump and put it on fan only to conserve water. There is a way to hook it up to a hose to avoid to having fill it up with water as often. It is still pretty cool without the pump because it is a strong fan. On warmer days you will be glad for the water to cool down the air. Read the directions that come with it and you will be fine. I highly recommend this unit if you live in a dry climate. ... show more

  • An excellent cooling fan at a very reasonable price.
Size: 1300 CFM
This is a terrific cooling fan, far better and more effective than I had hoped. Very simple to set up, with excellent instructions. It seems like it will have excellent durability, as well. I only deduct one star because it's a little tedious to keep refilling the reservoir throughout the day. It goes through a tank in about 4 hours. Attaching a hose would be pretty questionable inside the house, though of course it would solve the problem outdoors. We are using it as an assist to our central a/c during a pretty serious heatwave. With outdoor temps of 112F to 117F, the a/c just can't keep up. But this cooler is taking the 86 degree air inside, and cooling it down to an almost comfortable 78 -80 in a large room. It is not the recommended set-up, but it is working for us in this heat emergency. ... show more
