Evaporative coolers cool the air using a simple natural process: the evaporating water decreases the temperature of the air. A pump takes the water from a tank and dampens a large pad made of natural cellulose. A powerful ventilator aspires air through the filter. The water evaporates from the filter and decreases the temperature of the air by several degrees. The fresh and clean air flows into the room and cools it down.

This Elite evaporative cooler range has a 70L capacity and with air displacement of 4700m3 per hour.

An air cooler with an airflow of 4,700 m³/hour is ideal for a large room or commercial space up to 60 m² (approximately 650 sq. ft or 150 m³ in volume). 

Because of its high output, this size is specifically designed for environments that require high air circulation, such as:

This evaporative cooler in optimal conditions will reduce the temperature by up to 12 degrees!

REQUIRES NO EXTERNAL DUCTING.
Evaporative coolers work most effectively when the space you are cooling has sufficient ventilation. So unlike Air conditioning units you would open doors and windows.
The water tank on an evaporative cooler should be filled with clean tap water and emptied if the machine is not used for more than 24 hours.
