The Refurbished Hessaire MC37M Evaporative Cooler features easy-to-use controls, oscillation, and multiple fan speeds to cool indoor or outdoor areas up to 950 square feet. A high-velocity axial fan provides a strong, chilled airflow of 3,100 CFM into your space, delivering up to 30 degrees F of cooling. It only costs $0.03 per hour to operate this air cooler thanks to the incredible power efficiency. A set of caster wheels makes it easy to maneuver and position exactly where you want it, and a tray on the top keeps tools, water bottles, safety supplies, and more within easy reach.

• Cooling Media: Three hi-density XeL50 rigid media pads cool areas faster by allowing more air intake than the single panel in other swamp coolers.
• Water Tank: The water reservoir holds 10.3 gallons, providing up to three to four hours of continuous cooling airflow. A level indicator at the front shows how full the tank is at a quick glance.
• Oscillation: Turn on the air swing delivery system to evenly distribute the cool air in a wide, left-to-right coverage.
• Speed Controls: Choose from three speed options or turn the fan-only mode on to circulate air in a stuffy room.
• Casters: Four heavy-duty casters are included for installation and are stored inside the unit for easy transportation.

Note: Evaporative swamp coolers are most effective in dry climates with an average relative humidity of 40 percent or less.
