The area covered by a large open series fan with a diameter of 7.3m is approximately equal to the coverage area of 50 0.75m small fans.

When come to HVLS fans,many people feel confused what is the difference between HVLS fans and high-speed fans.Here，with simple sentence,you may find the answer.

KUULFANS series are the large range HVLS fans with diameters from 3.7 m to 7.3m. Different from traditional gearbox, it is very quiet at 39dbA and suitable for many places that require such quiet large fans. Featuring the world’s strongest PMSM, this quiet HVLS fan has a high electrical efficiency of 84%.

Now,a more cost-saving solution are large industrial ceiling fans – also known as HVLS fans (High Volume, Low Speed).

OPT HVLS fans used for large open space cooling and ventilation with large diameter from 3.7m to 7.3m,air volume can be 13200CMM,coverage areas is 1800CBM.

"KQ"series in the KUULFANS is the first self-design product with introducing western technology and 10 years upgrading.

High volume low speed (HVLS) fans generate a large volume of air that gently flows down to the ground. This air moves throughout the space, mixing and circulating air more efficiently. During the heating season, HVLS fan technology can destratify uneven temperatures that can be in excess of 5-10 degrees from ceiling to floor.

Exercising is the beat way to keep healthy and happy life.But it's hard to keep practising if you are in a bad situation,like hot air,bad smell or blocked environment.Now,with OPT HVLS,the energy cost of air conditioning and many sets small high-speed fans will not bother you any more.

How to overcome environment problems:too hot,too cold,too wet,only OPT HVLS fans.

Technically, an HVLS — high-volume, low-speed — fan is a ceiling fan greater than 8 ft in diameter. Unlike a small, high-speed fan that creates small, turbulent air streams that quickly disperse, an HVLS fan relies on size, not speed, to move a significant amount of air. Originally designed for large spaces such as warehouse and factories, HVLS fans have evolved as technology has rapidly improved. They now are found in a wide variety of industrial, commercial and residential spaces, often working in conjunction with HVAC systems for energy savings. In fact, energy-efficient HVLS fans have quickly assumed a leading role in the green building movement.

High-Volume, Low-Speed (HVLS) fans were installed in a typical dairy free-stall barn,which brings natural cooling and ventilation for cows and barn with no harm to cows.

HVLS fans distribute that incoming air, driving it quietly but forcefully to the floor where it jets to the walls before it rises to blend with the incoming air. HVLS fans not only move the air, but they also effectively de-stratify the air.

High-volume low-speed (HVLS) ceiling fans, like OPT's 6 blades "KQ series" Fan, are ideal for large open areas,such as factory,gym,restaurant,plant,and so on.
