Siboly evaporative air cooler is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems which use vapor-compression or absorption refrigeration cycles. Evaporative cooling works by employing water's large enthalpy of vaporization. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation), which can cool air using much less energy than refrigeration. In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for the comfort of building occupants.

1. New type blade,subjected to the tests of dynamic balance,ensures generation of a lot air volume at the reasonable blade angle and a good noise control

2. National patent aluminum alloy shutters with particular pneumatic opening and shutting mechanism,adopting the inclined belt to drive, ensure the shutters can open and shut fully to protect against wind or rain and dust.

3. Fan is subject to eight strict quality testing procedures—noise, vibration, dynamic balance,static balance, rotary concentric performance, blade rotating speed, overall effiniency test prior to shipment.

4.Can be conbined with cooling pads to form vertical ventilating and cooling system, which is the most inexpensive and effective cooling measure in summer

5. The cooling fans we produce are widely used in industrial workshop,civil field or aricultural fields…Our products enjoy high reputation at home and abroad and sell well in China, Southeastern Asia, Africa,Mid East,USA,Europe,etc.
