With 10 years' experience in industrial fan manufacturing and applications, we know air movement. From high velocity to high volume low speed fans, our industrial fans are YOUR OPTIMAL SOLUTION.

Permanent Magnet Synchronous Motor fan ( PMSM ) with less maintenance .It has huge diameters with a low rotational speed that can push a massive amount of air and decrease temperature up to 8 C.

Permanent Magnet Synchronous Motor (PMSM) is an AC synchronous motor whose field excitation is provided by permanent magnets.

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.

Keeping a comfortable air environment for commercial places like restaurant，malls, shopping outlets, convention centers, places of worship,more energy-saving,more quiet,free-maintenance.

HVLS fans are used widely inindustrial,commercial and agricultural areas.For barn cooling and ventilation,High volume low speed fans bring no harm to human body

high-volume low-speed (HVLS) fans that keep large open space air comfortable. High roof, heat generating motors and furnaces, and poor ventilation often work together to keep industrial spaces hot. The idea behind the HVLS fan originated 20 years ago from a research on agriculture industry. HVLS fans rotate slowly, at 20 to 65 rpm, powered by a motor of less than one horsepower. The concept behind the HVLS fan is to move large amounts of air slowly. The fan produces a soft, cooling breeze that is effective in mixing the air in the plant.

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

In summer,garage is large open space gathered many cars. For its cooling and ventilation,HVLS big size fan can cover 1800M2 with 13200CMM air volume

Personnel Cooling Natural Ventilation Dehumidification Energy-saving

HVLS (High Volume–Low Speed) industrial energy-saving fan, a huge ceiling fan with a diameter of 7.3 meters.It can promote a large amount of air movement more efficiently, producing a large air volume. The speed needs only 50RPM, which makes the space form a moving and circulating airflow field, which is unmatched by other equipment.

HVLS fans are different from traditional fans not only from the size but also the technology it used. To keep temperature balance and saving energy costs,HVLS fans will be your optimal choice.

In Shenzhen,China,the marketing Dep. manager Jacky was wondering how to improve the air quality in their show room." In Summer,the air in this room with transparent window design make the inside expose to the sunlight,the air in here is very hot and the costs of air conditioning increased heavily."

HVLS fans move slowly and distribute large amounts of air at low rotational speed warehouses, barns, hangars and distribution centers,shopping malls, churches, office buildings,restaurant, airport terminal buildings, fitness centers and schools.

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.
