Info & Guides

Description

The Hessaire MC37V Evaporative Coolers offer a powerful and easily portable cooling solution for large areas up to 950 square feet. This recently upgraded evaporative cooler can be used in various places, including outdoors, indoors, and covered porches.

 

Direct cool, moist airflow for fast relief outdoors or use the oscillating louvers to spread this airflow around hot, dry work areas like garages, repair shops, barns, stables, and other commercial spaces.

Note: Evaporative Swamp Coolers are most effective in dry climates with an average Relative Humidity of 40 percent or less.

Simple High Performance Design 

Featuring a simple-to-use design, the Hessaire MC37V 3,100 Cubic Feet Per Minute (CFM) Evaporative Cooler includes features: 

  • Three-sided high-grade Xel50 cooling media cools areas faster
  • Simple manual rotary controls
  • Adjustable louvers and automatic oscillation enable you to cover wide spaces
  • Multiple cooling and fan speeds for customization

Manual + Continuous Fill Options

Flexible water fill options are available to you when you have the swamp cooler indoors or outside near a garden hose. 

  • Manual Fill: Push on the spring-loaded front fill door for manual fill into the 10.3-gallon tank. Monitor water volume through the water level indicator. When the water limit hits “FULL,” start the internal water pump.
  • Continuous Fill: Assemble the continuous fill garden hose float adapter to the swamp cooler during assembly. The continuous fill method allows for a simple garden or coil hose connection that eliminates the need to manually watch and fill the water tank.

Powerful Airflow

Cooling the air is only a part of the process; propelling the chilled air into your space is what brings you the needed relief. Specially engineered features from Hessaire allow this mobile evaporative cooler to provide an airflow of 3,100 CFM to your area:

  • The cupped axial fan design allows it to not only provide a strong airflow to thrust chilled air into your space.
  • The air swing delivery system moves cool air left to right across the room to ensure that air is evenly distributed.
  • Axial fan can be adjusted between three fan speeds – Low, Medium, & High. 

Control Panel

Simple upkeep and easy-to-operate rotary controls make controlling this air cooler a snap.

  • Motor Speed Dial: Turn on the cooler and select your fan speed between Low, Medium, and High with the fan switch.
  • Pump: Switch the pump on to saturate the internal Xel50 Cooling Media.
  • Air Swing Delivery System: Turn the swing switch on or off for automatic oscillation.

Additional Features

  • Fan-Only: Use the swamp cooler on one of the three fan speeds without water just to propel air throughout a stuffy room.
  • Cup Holder: The Top cup holder is a great resting place for drinks.
  • Palm Design: Unique palm grill design provides an organic design.

Sylvane's Expert Take

Whether you need to cool down indoor or outdoor spaces, the Hessaire MC37M Evaporative Coolers are affordable and versatile cooling solutions. 

What Customers Love

  • Use Anywhere: Sylvane customers use this evaporative cooler in a variety of places: garages, patios, sunrooms, workshops, outdoor kitchens, and even greenhouses. 
  • Long Run Time: With the 10.3-gallon water tank, you’ll have three to four hours of continuous cooling. Hook it up to a water hose to constantly run without needing to refill.

Things to Consider

  • Caster Unpacking: The durable caster wheels are stored inside the unit for transportation and will need to be installed before the cooler's first use.

Reviews Summary
Customers say this evaporative cooler effectively cools outdoor spaces like patios and garages in hot climates. Many reviews mention its strong airflow and cooling performance, particularly in dry environments. The unit performs well in temperatures over 100 degrees, though effectiveness varies with humidity levels. Common feedback includes praise for the three-speed fan and easy water filling system. While most find it powerful and effective, some note it can be loud at high speeds and the plastic components feel lightweight. Frequent comments address its suitability for covered patios, garages, and workspaces. Reviews indicate regular water refills are needed during extended use.

    I would buy this product again.

    This unit is a great buy for the price. I was using a commercial floor fan before and it was very noisy even on low speed. This new cooler gets the job done, much quieter and the oscillating vane is great. Can't beat this machine. I recommend it!

    Very quiet.

    I bought this for my back porch and it works great. What I like about it compared to another cooler I have is how quiet it is.
