The Maxx Air 36 In. Evaporative Cooler is designed for cooling indoor industrial and commercial applications where an AC unit isn't feasible, including a shop, factory or warehouse, barn, auto garage, outdoor entertainment venue, sporting events, or a restaurant patio. Constructed using a durable polyethylene housing with large heavy-duty aluminum fan blades, this portable swamp cooler is built to resist wear and tear and is built using an energy-efficient motor and pump to remain wallet-friendly throughout it's operational life. Our 36 in. air cooler arrives fully assembled and can be moved to your desired location with ease using the built-in caster wheels. Experience a lowered ambient temperature in spaces up to 2,600 sq. ft. by as much as 26°F without air conditioning. Connect to a direct water line or use the available 10 gallon reservoir for independent usage.
