Hessaire M250 5,300 CFM Portable Evaporative Cooler - he13157
Cut cooling costs with the Hessaire M250 5,300 Cubic Feet Per Minute (CFM) Evaporative Cooler. This mobile evaporative swamp cooler is great for use in hot, dry climates or for those who want to lower their reliance on air conditioners in industrial environments. Capable of cooling the air in spaces up to 1,600 square feet, it’s ideal for use in warehouses, garages, workshops, or outdoor decks and patios.
Three-sided cooling media allows it to disperse more air than other coolers without sacrificing performance by expanding the intake areas to the high density XeL50 rigid media panels.
Commercial + Industrial Applications
Weighing only 57-pounds, it’s easy to roll from area to area on its heavy-duty caster wheels, which is convenient for rolling across bare concrete flooring or rough, uneven floors. Standing just over 3 ¾ feet tall and 1.4 feet wide, it provides a powerful performance without taking up a lot of space in mechanic shops, warehouses, hangars, and more.
The Hessaire M250 model features high visibility yellow trim around the air louvers, the casters, the side & back vents, the control panel, and the power cord. This makes it easier to see for added safety in industrial areas.
Economical, Smart Cooling
Lower the temperature in medium-sized work environments without the need for costly air conditioners. The Hessaire M250 provides cooling to areas up to 1,600 square feet without putting a dent in your wallet.
Unlike other swamp coolers that only have cooling media on 1 side, this portable evaporative cooler features high-density rigid media on 3 sides. The cooling process happens when air is drawn into the unit and passes over the pads. The cooled air is then pushed out on 3 sides of the unit and into your space.
Powerful Airflow
You’ll enjoy powerful cooling relief with the mobile M250. Created with unique features from Hessaire, it’ll deliver up to 5,300 CFM of airflow to the areas you need it most. An innovative cupped axial fan design ensures plenty of cool, fresh air flows through. Additionally, the air swing delivery system propels air throughout the space, using left to right louvers.

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.
