Products Description

Cooling principle

When the cooler is operating, water is pushed from the water tank to the water distributor, where it is equally distributed to the evaporative cooling pads before returning to the tank. Prior to being delivered to the user space, the outdoor hot air is drawn via the wet cooling pads, filtered, and has its temperature decreased.

How does evaporative air cooler work?

Fresh outdoor air is continuously brought into the indoor room through the air duct and air supply outlets after being filtered and cooled by an evaporative air cooler. The indoor environment will be in a positive pressure state due to the constant flow of fresh air, which will cause the initial hot air that included odor and dust to be expelled out of the space and leave behind a cool, ventilated, tidy, and comfortable environment. For any evaporative air conditioning system to operate satisfactorily, a suitable exhaust area and an efficient exhaust are necessary.

Supply Air Temperature

The "dryness" of the outside air determines the supply air temperature. The temperature of the web bulb decreases as the outside air becomes dryer. The ability to reduce temperature is increased.
When the outside air is hot and dry, evaporative cooling performs at its optimum. For information on temperature drop (supplied air temperature with air cooler) under various humidity and temperature circumstances, see the datasheet below.
The secondary cooling effect known as the "wind-chill effect" occurs when air moves over human skin, creating an effect like to that produced by a fan and making it feel cooler. The Supply Air Temperature and Air Velocity both affect the Wind-Chill Effect.


Why Evaporative Air cooler?

  1. 100% copper high-quality motor, With iron casting housing, more durable and steady;
  2. Upgraded high-efficiency cooling pad with fixing frame—Higher cooling efficiency and better protection for the core cooling media;
  3. Integrated one-piece fan blades with patent structure and design, Low noise, and high airflow;
  4. Strong PP engineering plastic structure with Anti-aging and Anti-UV material, long life span;
  5. Vertical water inlet valve to make sure, stable water inlet supply with minimum blockage;
  6. LCD and mechanical control board, optional for auto/mechanical control system;
  7. The open-type water distribution system can make water be distributed evenly onto a cooling pad;
  8. Specially designed air inlet shutter shape to ensure maximum air inlet while can keep rain and dust outside.



The cooling capacity of this air cooler is 20000 CMH, which means it can cool a large area up to 2000 square feet.

Yes, this air cooler is designed for indoor and outdoor use and can effectively cool large areas in both settings.

The air cooler uses evaporative cooling technology, where water is circulated over honeycomb cooling pads and then evaporates, resulting in cool air that is pushed out into the surrounding area.

No, this air cooler is portable and does not require any installation or setup. Simply plug it in, add water, and turn it on.

Yes, this air cooler is energy-efficient and uses only a fraction of the energy consumed by traditional air conditioning systems.

The frequency of refilling the water tank depends on the usage and humidity levels in the area. On average, the water tank needs to be refilled every 3 to 4 hours.

Yes, this air cooler is effective in all climates, including humid climates. However, it works best in dry climates with low humidity levels.

Yes, this air cooler comes with a one-year warranty, which covers any defects or malfunctions in the product.
