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

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.

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.

What our Experts Think

• 
  

  Industrial-grade cooling power — Delivers 11,000 CFM airflow, moving massive volumes of cool moisture across up to ~3,000 sq ft, perfect for large garages, warehouses, run-off events, barns, and commercial spaces.

  
  


• 
  

  Exceptional value with refurbishment — Factory-refurbished unit backed by a one-year limited warranty, offering like-new performance at a lower cost than a new MC92V model.

  
  


• 
  

  User-friendly & versatile — Dual water fill options (manual or continuous hose hookup), easy dials for fan speed/pump/oscillation, and adjustable louvers help tailor airflow and cooling where you need it.

  
  


• 
  

  Built-for rugged use — Large 32.8 gallon water reservoir, heavy-duty pads, oscillating design, and caster wheels support long runtime, broad coverage, and easy mobility.

  
  


• 
  

  Energy-efficient operation — Runs on modest power (≈460 W) with low operating costs (~$0.05/hour), balancing high flow with economical performance.

  
  


• 
  

  Best in dry climates — As with all evaporative coolers, peak performance occurs in low-humidity environments; in humid regions, cooling feels less effective and adds moisture to the air.

  
  


• 
  

  Ideal for demanding spaces — Experts highlight its strength for industrial, commercial, and large open spaces where standard fans or small coolers can’t compete.
