How it Works

In hot summer, evaporative air cooler cools the air by evaporation. In each air cooler, there is a water reservoir (tank), motorized pump, water distribution system, cooling pads and fan/blower. With the help of pump, water is pumped up from the water reservoir (tank) and through the water distribution system the water is dropped on cooling media (i.e. Cellulose Paper Pads or Aspen Pads). The blower/fan sucks the outside hot air and this hot air passes through wetted cooling media. The water evaporation takes place and air temperature drops. This cool air is then thrown inside the cooling area which in turn offers cool and fresh air.
Evaporative coolers are rated by the cubic feet per minute (cfm) of air that they deliver to the house. Most models range from 3,000 to 25,000 cfm. Manufacturers recommend providing enough air-moving capacity for 20–40 air changes per hour, depending on climate.

Product Usage

Evaporative air cooling is most effective, where the air is hot and humidity is low, such as in the south western part of the United States. However, in high humidity areas like coastal belts, there are many cost effective uses of evaporative cooling that make it the right choice. For example, industrial plants, commercial kitchens, laundries, dry cleaners, tanning parlours, and any other situation where the air tends to be dry as a result of the business type.


Expert Review

An evaporative cooler should have at least two speeds and a vent-only option. During vent-only operation, the water pump does not operate and the outdoor air is not humidified. This lets you use the evaporative cooler as a whole-house fan during mild weather.
Control the cooler's air movement through the house by adjusting window openings. Open the windows or vents on the leeward side of the house to provide 1–2 square feet of opening for each 1,000 cfm of cooling capacity. Experiment to find the right windows to open and the correct amount to open them. If the windows are open too far, hot air will enter. If the windows are not open far enough, humidity will build up in the home.
You can regulate both temperature and humidity by opening windows in the areas you want to cool, and closing windows in unoccupied areas. Where open windows create a security issue, install up-ducts in the ceiling. Up-ducts open to exhaust warm air into the attic as cooler air comes in from the evaporative cooler. Evaporative coolers installed with up-ducts will need additional attic ventilation.
Optional filters remove most of the dust from incoming air—an attractive option for homeowners concerned about allergies. Filters can also reduce the tendency of some coolers to pull water droplets from the pads into the blades of the fan. Most evaporative coolers do not have air filters as original equipment, but they can be fitted to the cooler during or after installation.


A portable evaporative air cooler provides substantial energy saving over refrigerated air units/air conditioners. The simplicity of design ensures negligible maintenance cost. Evaporative cooler provides you fresh filtered air. Thus a portable evaporative air cooler gives you cool and filtered fresh air, which is free from C.F.C and has low acquiring, maintenance and running (electricity) costs.


Warranty: 90 days labor, 1 year parts
