HVLS is the English abbreviation of "high volume, low speed", HVLS fan is a major invention in the field of industrial ventilation in the new era. HVLS fan of Vanse is created from excellence and meticulous design, combined with exquisite manufacturing technology, strict detection and meticulous quality control means, characterized by cost-effective.

Traditional industrial fans often produce cooling effect by high-speed rotation of fan blades, which blow high-speed airflow across the human body surface, resulting in rapid evaporation of body surface liquid. However, after a long time of blowing, we usually feel dry and hot. As its coverage is very small, when there is personnel flow,  limitations of small fans will be reflected. On the contrary, HVLS fan drives vast amounts of air in a large area through the slow rotation of super large blades, generates a super large and soft low-speed natural breeze in an all-round way, continuously blows the wet air layer on the body surface, effectively promotes the evaporation on the body surface, so as to bring people the best cooling effect. Through the evaporation effect produced by the super large fan, people can feel the temperature drop by 37.-41°F in the large covered space, which effectively solves the ventilation problem of large space.
