- It reduces heat in the working room.
- It effectively keeps the temperature inside the working room lower than out in air conditioning(A/C).
- Feel cooling and more comfortable
- Turn down the temp. - 4℃ at 3m/sec air flow
For the same spaces, a small high-speed fan cannot produce the same effect as a large low-speed fan, even with a high rotation speed. The power needed to drive the fan is generally increased to the third power of the average airspeed passing through the fan. That is, a small commercial fan providing air at 20 miles per hour (mph) requires about 64 times more power than a similarly-sized fan delivering air at 5 mph. If the purpose of the fan is to cool down the heat for people or animals, the speed of air combined with the “efficiency” of the fan means that the large low-speed fans are more efficient and effective than the small high-speed fans.
8 hours per day operation with one HVLS fan with 3m diameter
2kWh power consumption (about KRW 240 won)
Keeps the floor space of 150~300sqm (50~100 pyeong) cool!

ASHRAE, the American Society of Heating, Refrigerating and Air-Conditioning Engineers, estimated and announced that the installation of HVLS fans can reduce costs by up to 49%. According to several independent studies, the HVLS fans are as effective as 12 high-speed fans and reduce electricity consumption by 86%. ASHRAE also announced that HVLS Fan has a great effect on the lowering the sensible temperature.
The current produced by the suggested “AIR 180®” which is lower than 3.0m/s has the effect of decreasing the wind chill temperature of a worker in the factory, but does not create a situation where noise, dust, or other factors disturb the actual work.
The air expands with increased vapor pressure via a continuous horizontal jet stream from the floor. Through this procedure, space for extra vapor is made and air humidity decreases while the wind is blowing. Vapor evaporation effect within the air removes indoor humidity, suppressing indoor mold, virus, and harmful bacteria growth, creating a healthy environment and extending the preservation period and freshness of all sorts of vegetables, grains, and products, and also has the effect of extending the life expectancy of equipment and facilities in the factory
