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

    • Great Evaporative Cooler if You Live in Low Humidity Place
Size: 3,100 CFM
I live in Tucson, Arizona where many houses used to only have these units on the roof for cooling. We call them Swamp Coolers. They will only work in a low humidity environment or you might as well just buy a big fan. Water runs over the filters, the big fan sucks in warm air and evaporates the water, the temp is lowered up to 25 degrees, and you have nature’s air conditioning, just like you on a hot, sweaty, breezy, desert afternoon! I bought this in July. We were replacing a 16 yo Mobile Mastercool that was made of metal and the doors were rusted out at the bottom. I saw they had these at the local Big Box Hardware Store and I was skeptical because none were on display. I was able to get a better deal here so I gave it a shot. We use the cooler on our patio under our awning. As long as it isn’t monsoon season, it drops the temp a good 25 degrees. The 3-Fan speeds are great and the oscillating feature works great. I’ve told my wife several times to turn it down because I was freezing out on a 90 degree night. The fan is very powerful which helps with the evaporation off the side and back pads. My only complaints are the plastic back panel is a little flimsy and kind of a pain to seat. If you can get the float right, hopefully you are replacing the cardboard panels only once every couple years. Replace the cardboard panels you say. Depending on how hard the water is in your area the panels over time will build up scale on them and will no longer have a good flow for the water and will need to be replaced. I’ll admit I have gone five or more years at a time but it really does work best for airflow if you replace them every couple years. A lot of this does depend on the hardness of the water in your area. My second dislike about this unit is the float. It is a plastic apparatus set up that is positioned in the corner by the side panel. First of all make sure you cut away a little extra of the cardboard so the float can move freely. I have had a very hard time getting the float to stop where I want it to be so I can just leave the hose on. When it is really hot and evaporated quickly if I have the hose bib on a very low flow it often times just fills enough and doesn’t overflow. But once you turn the fan off when you come out in the next morning there will be all kinds of water on the ground around the unit. I’m sure I can fix this I just haven’t wanted to waste an hour and a half trying to get the level perfect. If it starts to overflow I just turn it off for a while. You can tell when it is running low by looking at the float on the front of the unit. I’m sure the manufacture will reply that you should never leave the hose bib on it unattended anyways. Overall I am extremely happy with this unit. I did buy an extended warranty to make sure that the unit would be covered at least for three years. I will give an updated review next year since now it is our fall/winter and we aren’t using the unit again until most likely April. ... 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
