Hessaire MC37M Portable Evaporative Cooler – 3100 CFM Swamp Cooler with 10.3-Gallon Tank for Garages & Patios

Why This Product Stands Out

When the summer heat makes your garage, workshop, or patio unbearable, the Hessaire MC37M delivers serious relief. Rated for a powerful 3,100 CFM of airflow and backed by a solid 4.3-star average from over 4,700 owners, it is one of the most trusted portable evaporative coolers on the market — a go-to pick for anyone who needs heavy-duty cooling without the installation cost of central air.

Key Features

• 3100 CFM airflow: Moves a massive volume of cooled air to cover garages, barns, and outdoor living spaces
• 10.3-gallon water tank: Runs 3–4 hours per fill, so you are not constantly refilling
• 3-panel intake design: Maximizes the evaporative surface for noticeably cooler output
• 80% larger evaporation surface: Cools more efficiently than typical portable coolers
• Quiet operation: Low-noise delivery system keeps vibrations and hum to a minimum
• Simple controls: Just fill, plug in, and switch on — no complicated setup

Design & Quality

Hessaire has been engineering air movement and cooling solutions since 1996, and the MC37M shows it. The housing is molded from lightweight polypropylene resin, making it durable enough for everyday use yet easy to move around. Its energy-efficient design delivers serious cooling power without the electricity bill of a traditional AC unit.

What’s Included

The MC37M ships complete with the cooler unit, water distribution system, and easy-fill tank components. It is ideal for homeowners, DIYers, and anyone cooling a space that standard AC cannot reach.
