The Maxx Air 36 In. Evaporative Cooler is designed for indoor industrial and commercial applications where AC cooling isn't feasible, including shops, factories and warehouses, barns, outdoor entertainment venues and sporting events. Constructed using a durable polyethyle housing with heavy-duty aluminum fan blades, this fan 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. model arrives fully assembled and can be moved to your desired location with ease using the built-in casters. 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.
