For 11 years,OPT focused on the upgrade of HVLS fans,to provide more safe and energy-saving fans.

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.

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.

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.

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.

HVLS fans KQ series 24ft fans can move large volumes of air. In fact, a single fan can cover an area up to 22,000 square feet and can replace as many as 50 small high speed fans.

OPT explore how HVLS fans can contribute to temperature balance in low energy costs, increase thermal comfort, and provide a silent and elegant design strategy. We discuss how to save energy and improve indoor air quality for building occupants.

In large spaces, heating by using air conditioning becomes very difficult: the heated air will move upward, forming a great stratification of heat and cold, and the heat will be all concentrated at the top of the building. (The space above the heat source, every rise of 1m, the temperature rises 1-2 ℃.) It not only means serious energy consumption, waste of cost expense, but also means that the ground will never reach the temperature you want!

Our fans are big with 2.6m height.If your places are not large enough,please find others.We only manufacturing big mobile fans for industrial,commercial usages.

The bigger they are, the harder they are to maintain.Large industrial facilities such as warehouses and manufacturing plants present a huge operational challenge because of their size. With extremely tall roof and a lot of square footage to cover, cooling or heating of factories—as well as keeping its workers comfortable—is difficult. The solution: OPT HVLS big ceiling fans provide a comfortable climate and reduce costs for large industrial facilities.

1. Application Industry Machinery processing, logistics warehousing, automotive/motorcycle, energy and electricity, white home appliances, elevator packaging and other industries

1. The formation of a large area and gentle breeze blowing. 2. To enhance the air circulation in all-round and multi-angle.

Three-dimensional natural breeze Large industrial fan comfort is not comparable to other fans, under the large energy-saving fan,

The wind speed generated by "industrial big fan" is about 2-3 m/s. Is entirely based on the airflow across the human skin to produce the best cool feeling of the air flow calculated,

Industrial large ceiling fan generated by the fresh air and indoor stay can be continuously fully mixed,
